 近年、嗜好の多様化の一例として、においに関する製品が多く販売されている。例えば、香水、パルファム、オーデパルファム等の人体に用いられるフレグランスや、ルームフレグランス等の様々な形態で、芳香を放つ製品が提供されている。芳香を放つ製品には、天然香料や合成香料が含有されている。また、体臭や生活臭のような不快な臭いを除去する目的の製品も提供されている。臭いを除去するための製品では、例えば、特定の臭い成分を化学的に分解する化学的消臭法や、特定の臭い成分を包摂あるいは吸着することで臭い成分が拡散することを防ぐ物理的消臭法が用いられている。また、臭いを除去するための製品では、特定の臭いを放つ細菌の繁殖を抑制する生物的消臭法や、マスキングやペアリングのように他の香りを利用して臭いを感じなくさせる感覚的消臭法も用いられている。
An embodiment of a thin film, a transfer sheet, and a transfer sheet container will be described with reference to the drawings.
In recent years, as an example of diversification of tastes, many products related to odors have been sold. For example, fragrances used for the human body such as perfumes, parfums, and eau de parfums, and various forms such as room fragrances are provided to give off fragrance. Fragrant products contain natural and synthetic fragrances. In addition, products for the purpose of removing unpleasant odors such as body odor and daily life odor are also provided. Products for removing odors include, for example, a chemical deodorizing method that chemically decomposes a specific odorous component, or a physical deodorizing method that prevents the odorous component from diffusing by including or adsorbing a specific odorous component. The odor method is used. In addition, in products for removing odors, biological deodorant methods that suppress the growth of bacteria that emit a specific odor, and sensory methods that use other scents such as masking and pairing to eliminate the odor. A deodorant method is also used.
 しかしながら、こうしたにおいに関する製品の多くは液状であるため、芳香や消臭のための成分が揮発しやすい。また、スプレーによって液状の製品を皮膚に吹きかけて用いる場合には、汗等によって上記成分が流れてしまうことや、衣服と皮膚とが擦れたときに上記成分が衣服に転移してしまうことが起こる。そのため、においを扱う新たな製品が求められている。本実施形態では、薄型フィルムに、においに関する機能を付与することで、嗜好の多様化に対応した、においを扱う新たな製品を提供する。 However, since many of these odor-related products are liquid, the components for fragrance and deodorization tend to volatilize. In addition, when a liquid product is sprayed onto the skin by spraying, the above-mentioned components may flow due to sweat or the like, or the above-mentioned components may be transferred to the clothes when the clothes and the skin rub against each other. .. Therefore, there is a demand for new products that handle odors. In the present embodiment, by imparting a function related to odor to a thin film, a new product for handling odor is provided, which corresponds to diversification of tastes.
 [薄型フィルムの構成]
 薄型フィルムの形態として、第1形態~第7形態の7つの形態を説明する。まず、これらの形態に共通する本実施形態の薄型フィルムの特徴について説明する。
[Composition of thin film]
As the form of the thin film, seven forms of the first form to the seventh form will be described. First, the features of the thin film of the present embodiment common to these embodiments will be described.
 図1が示すように、薄型フィルム10は、被着体に貼り付けられる第1面11Fと、第1面11Fと反対側の面である第2面11Rとを備えている。第2面11Rは、薄型フィルム10が被着体に貼り付けられたときに、被着体とは反対側に位置する最外面となる。薄型フィルム10は、香料成分や抗菌成分である機能成分を保持する保持層を含む1以上の層から構成される。 As shown in FIG. 1, the thin film 10 includes a first surface 11F to be attached to an adherend and a second surface 11R which is a surface opposite to the first surface 11F. The second surface 11R is the outermost surface located on the opposite side of the adherend when the thin film 10 is attached to the adherend. The thin film 10 is composed of one or more layers including a holding layer that retains a functional component that is a fragrance component or an antibacterial component.
 薄型フィルム10は、当該フィルム単独で被着体に対する接着性を発現する程度に薄く、言い換えれば、上記接着性を発現する程度に、単位面積当たりの質量が小さい。具体的には、薄型フィルム10の単位面積当たりの質量は、5.0g/m以下である。単位面積当たりの質量が5.0g/m以下であれば、被着体の表面形状に対する薄型フィルム10の追従性が良好に得られるため、薄型フィルム10と被着体との密着性が高められる。また、被着体が皮膚である場合、薄型フィルム10の単位面積当たりの質量が5.0g/m以下であれば、薄型フィルム10の貼付部分にて皮膚が引っ張られるような感覚を使用者が覚えにくい。 The thin film 10 is thin enough to exhibit adhesiveness to the adherend by itself, in other words, the mass per unit area is small enough to exhibit the adhesiveness. Specifically, the mass per unit area of the thin film 10 is 5.0 g / m 2 or less. When the mass per unit area is 5.0 g / m 2 or less, the thin film 10 can follow the surface shape of the adherend well, so that the adhesion between the thin film 10 and the adherend is improved. Be done. Further, when the adherend is skin, if the mass per unit area of the thin film 10 is 5.0 g / m 2 or less, the user feels that the skin is pulled by the portion where the thin film 10 is attached. Is hard to remember.
 また、薄型フィルム10の単位面積当たりの質量は、0.01g/m以上である。単位面積当たりの質量が0.01g/m以上であれば、薄型フィルム10の強度が良好に得られるため、薄型フィルム10に破れ等の欠陥が発生しにくくなる。また、単位面積当たりの質量が0.01g/m以上であれば、連続した膜状に薄型フィルム10を形成することが容易である。 The mass of the thin film 10 per unit area is 0.01 g / m 2 or more. When the mass per unit area is 0.01 g / m 2 or more, the strength of the thin film 10 can be obtained satisfactorily, so that defects such as tearing are less likely to occur in the thin film 10. Further, when the mass per unit area is 0.01 g / m 2 or more, it is easy to form the thin film 10 in the form of a continuous film.
 なお、上記単位面積当たりの質量は、平面視にて1mの面積を有する部分あたりに換算した薄型フィルム10の質量である。単位面積当たりの質量は、例えば、複数の測定領域で測定された質量の平均値から換算すること、あるいは、薄型フィルム10の膜厚の平均値に薄型フィルム10の密度を掛けることによって求められる。薄型フィルム10の密度は、例えば、1g/cm以上3g/cm以下である。 The mass per unit area is the mass of the thin film 10 converted per portion having an area of 1 m 2 in a plan view. The mass per unit area can be obtained, for example, by converting from the average value of the mass measured in a plurality of measurement regions, or by multiplying the average value of the film thickness of the thin film 10 by the density of the thin film 10. The density of the thin film 10 is, for example, 1 g / cm 3 or more and 3 g / cm 3 or less.
 薄型フィルム10において、気体の透過性の低さを示すパラメータである閉塞率は、5%以上60%以下であることが好ましい。閉塞率は、薄型フィルム10が配置された箇所での、ヒトの体温と等しい温度を有する水の蒸散量を、薄型フィルム10が配置されない場合の蒸散量に対して抑える割合である。閉塞率が高いことは、薄型フィルム10内に気体分子の透過可能な経路が少ないことを意味し、すなわち、薄型フィルム10の内部に含まれる機能成分が揮発して薄型フィルム10外へ出ていきにくいことを意味する。 In the thin film 10, the blockage rate, which is a parameter indicating low gas permeability, is preferably 5% or more and 60% or less. The occlusion rate is a ratio of suppressing the amount of transpiration of water having a temperature equal to the human body temperature at the place where the thin film 10 is placed to the amount of transpiration when the thin film 10 is not placed. A high occlusion rate means that there are few paths through which gas molecules can permeate in the thin film 10, that is, the functional components contained in the thin film 10 volatilize and go out of the thin film 10. It means that it is difficult.
 閉塞率が5%以上であれば、薄型フィルム10の外部への機能成分の拡散が短時間に起こることが抑えられ、機能成分の徐放性が良好に得られる。閉塞率が60%以下であれば、機能成分による芳香や抗菌の機能が十分発揮される程度に、機能成分の拡散性が得られる。特に、機能成分が揮発しやすい香料成分を含む場合に、閉塞率が5%以上60%以下であることによる上記効果が高く得られる。 When the blockage rate is 5% or more, diffusion of the functional component to the outside of the thin film 10 is suppressed in a short time, and the sustained release property of the functional component can be obtained well. When the obstruction rate is 60% or less, the diffusibility of the functional component can be obtained to the extent that the aroma and antibacterial functions of the functional component are sufficiently exhibited. In particular, when the functional component contains a fragrance component that easily volatilizes, the above-mentioned effect is highly obtained when the blockage rate is 5% or more and 60% or less.
 また、閉塞率が高いほど、被着体表面からの水の蒸散が抑えられる。例えば、美容用途に薄型フィルム10が用いられ、薄型フィルム10が皮膚に貼り付けられる場合、閉塞率が5%以上であれば、薄型フィルム10の貼り付けによって、皮膚の保湿効果が良好に得られる。また、医療用途において、湿潤によって創傷治癒環境を改善する湿潤療法や、皮膚への薬剤浸透を高める閉鎖密封法に薄型フィルム10が用いられる場合、閉塞率が30%以上であれば、薄型フィルム10を生体組織表面に貼り付けることによって、生体組織表面に水分過多の状態を好適に形成できる。そのため、湿潤環境での治癒促進効果や薬剤の浸透促進効果が良好に得られる。 Also, the higher the blockage rate, the more the evaporation of water from the surface of the adherend is suppressed. For example, when the thin film 10 is used for beauty purposes and the thin film 10 is attached to the skin, if the obstruction rate is 5% or more, the thin film 10 can be attached to obtain a good moisturizing effect on the skin. .. Further, in medical applications, when the thin film 10 is used for a moisturizing therapy that improves the wound healing environment by moistening or a closed sealing method that enhances drug penetration into the skin, if the occlusion rate is 30% or more, the thin film 10 Can be suitably formed on the surface of the living tissue in a state of excess water by attaching the above to the surface of the living tissue. Therefore, the healing promoting effect in a moist environment and the penetration promoting effect of the drug can be satisfactorily obtained.
 閉塞率は、薄型フィルム10が配置されない場合の蒸散量に相当する基準水分蒸散量と、薄型フィルム10が配置されている場合の蒸散量に相当する対象水分蒸散量とを用いて、下記式(A)によって算出される。 The blockage rate is determined by using the reference water transpiration amount corresponding to the transpiration amount when the thin film 10 is not arranged and the target water transpiration amount corresponding to the transpiration amount when the thin film 10 is arranged. Calculated by A).
 閉塞率(%)=(基準水分蒸散量-対象水分蒸散量)/基準水分蒸散量×100 ・・・式(A)
 各水分蒸散量は、以下の方法によって測定される。
Blockage rate (%) = (reference amount of water evaporation-target amount of water evaporation) / reference amount of water evaporation x 100 ... formula (A)
Each water evaporation amount is measured by the following method.
 (1)37℃に保たれたウォーターバスの温水を任意の容積を有する容器内に循環させる。該容器にガラス瓶を入れ、ガラス瓶内に、ガラス瓶の開口から垂直方向に4cm離れる位置まで、37℃の温水を入れる。 (1) Circulate hot water in a water bath kept at 37 ° C in a container having an arbitrary volume.

Cover and leave for 5 minutes.
 (3)経皮水分蒸散量測定器(ASCH JAPAN社製:VAPO SCAN AS-VT100RS)を用い、プローブを直径10mmに合わせて、上記(2)の操作後のプラスチック板の穴の位置での水分蒸散量を、メンブレンフィルター上で測定し、測定した値を基準水分蒸散量とする。 (3) Using a percutaneous moisture evapotranspiration measuring device (ASCH JAPAN: VAPO SCAN AS-VT100RS), adjust the probe to a diameter of 10 mm, and adjust the probe to the diameter of 10 mm, and the moisture at the position of the hole in the plastic plate after the operation of (2) above. The amount of evapotranspiration is measured on a membrane filter, and the measured value is used as the reference amount of water evapotranspiration.

 (5)上記経皮水分蒸散量計測器を用い、上記(3)と同様に、上記(4)の操作後のプラスチック板の穴の位置での水分蒸散量を、薄型フィルム10上で測定し、測定した値を対象水分蒸散量とする。 (5) Using the percutaneous moisture evapotranspiration amount measuring instrument, the moisture evapotranspiration amount at the position of the hole of the plastic plate after the operation of the above (4) is measured on the thin film 10 in the same manner as the above (3). , Let the measured value be the target water evapotranspiration amount.
 以下、第1形態~第7形態の薄型フィルム10を順に説明する。
 図2は、第1形態の薄型フィルム10である薄型フィルム10Aの構造を示す。薄型フィルム10Aは、機能成分を保持する保持層20のみを備えている。第1形態においては、第1面11Fと第2面11Rとの双方が、保持層20の有する面である。
Hereinafter, the thin films 10 of the first to seventh forms will be described in order.
FIG. 2 shows the structure of the thin film 10A, which is the thin film 10 of the first form. The thin film 10A includes only a holding layer 20 that retains the functional components. In the first form, both the first surface 11F and the second surface 11R are surfaces of the holding layer 20.
 保持層20は、高分子材料に混合された状態で、機能成分を含有している。言い換えれば、保持層20においては、高分子材料のネットワーク中、すなわち、高分子鎖の隙間に、機能成分が入り込んでいる。 The holding layer 20 contains a functional component in a state of being mixed with a polymer material. In other words, in the holding layer 20, the functional component is contained in the network of polymer materials, that is, in the gaps between the polymer chains.
 保持層20を構成する高分子材料としては、公知の材料が用いられる。例えば、保持層20を構成する高分子材料は、ポリエステル、ポリオレフィン、ポリアミド、ポリイミド、ポリビニルアルコール、ポリウレタン、ポリ酢酸ビニル、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、アクリル樹脂、ポリシロキサン類、セルロースやキチンやキトサン等の多糖類、カゼイン等の各種のたんぱく質、ゴム、これらの高分子化合物の誘導体、変性体、共重合体、混合物である。保持層20を構成する高分子材料は、機能成分との親和性、機能成分の保持能力、閉塞率の向上機能等を考慮して選択されればよい。また、被着体が生体である場合には、保持層20を構成する高分子材料は生体適合性を有することが好ましい。 A known material is used as the polymer material constituting the holding layer 20. For example, the polymer materials constituting the holding layer 20 include polyester, polyolefin, polyamide, polyimide, polyvinyl alcohol, polyurethane, polyvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polycarbonate, acrylic resin, polysiloxanes, cellulose and chitin. Polysaccharides such as and chitosan, various proteins such as casein, rubber, derivatives of these polymer compounds, modified products, copolymers, and mixtures. The polymer material constituting the holding layer 20 may be selected in consideration of the affinity with the functional component, the holding ability of the functional component, the function of improving the blockage rate, and the like. When the adherend is a living body, it is preferable that the polymer material constituting the holding layer 20 has biocompatibility.
 機能成分は、香料成分および抗菌成分の少なくとも一方である。保持層20が香料成分を含むことにより、薄型フィルム10から芳香が放たれる。また、保持層20が抗菌成分を含むことにより、薄型フィルム10が貼り付けられた被着体において細菌の繁殖が抑えられ、その結果、細菌に起因した臭いの発生が抑えられる。 The functional ingredient is at least one of a fragrance ingredient and an antibacterial ingredient. When the holding layer 20 contains a fragrance component, the fragrance is released from the thin film 10. Further, since the holding layer 20 contains an antibacterial component, the growth of bacteria is suppressed in the adherend to which the thin film 10 is attached, and as a result, the generation of odor caused by the bacteria is suppressed.
 薄型フィルム10Aの全体の質量に対する、薄型フィルム10Aに含まれる機能成分の総質量の割合は、50ppm以上30%以下であることが好ましい。機能成分の質量の割合が50ppm以上であれば、機能成分による効果、すなわち、香料成分による芳香効果や抗菌成分による抗菌効果が良好に得られ、また、機能成分による効果の持続性も良好に得られる。機能成分の質量の割合が30%以下であれば、機能成分による効果が過剰になること、例えば、芳香が強くなりすぎることが抑えられ、また、被着体が生体である場合には、機能成分が生体に与える刺激を抑えられる。 The ratio of the total mass of the functional components contained in the thin film 10A to the total mass of the thin film 10A is preferably 50 ppm or more and 30% or less. When the mass ratio of the functional component is 50 ppm or more, the effect of the functional component, that is, the fragrance effect of the fragrance component and the antibacterial effect of the antibacterial component can be obtained well, and the sustainability of the effect of the functional component can be obtained well. Be done. When the mass ratio of the functional component is 30% or less, the effect of the functional component becomes excessive, for example, the aroma becomes too strong, and when the adherend is a living body, the function is suppressed. The irritation given to the living body by the ingredients can be suppressed.

 保持層20は、機能成分として複数の種類の物質を含んでいてもよい。また、保持層20は、機能成分として、香料成分と抗菌成分との双方を含んでいてもよいし、香料成分および抗菌成分の両方として機能する物質を含んでいてもよい。 The holding layer 20 may contain a plurality of types of substances as functional components. Further, the holding layer 20 may contain both a fragrance component and an antibacterial component as a functional component, or may contain a substance that functions as both a fragrance component and an antibacterial component.
 なお、第1形態において、薄型フィルム10Aは、複数の保持層20を備えていてもよい。複数の保持層20が機能成分として互いに異なる物質を含む構成であれば、1つの層に含有させにくい複数の物質であっても、これらの物質を1つの薄型フィルム10Aに含有させることが可能である。 In the first form, the thin film 10A may include a plurality of holding layers 20. If the plurality of holding layers 20 are configured to contain substances different from each other as functional components, even if a plurality of substances are difficult to be contained in one layer, these substances can be contained in one thin film 10A. is there.
 また、複数の保持層20のうち、第2面11Rに近い層ほど、機能成分の外部への拡散が早くに生じる。したがって、例えば、複数の保持層20が互いに異なる香料成分を含む構成であれば、時間の経過とともに発する芳香が変わる薄型フィルム10Aが実現できる。また、複数の保持層20が互いに異なる濃度の香料成分を含む構成であれば、各保持層20が含有する香料成分の濃度の調整によって、時間の経過に沿った芳香の強さの調整が可能である。 Further, among the plurality of holding layers 20, the layer closer to the second surface 11R causes the functional component to diffuse to the outside earlier. Therefore, for example, if the plurality of holding layers 20 are configured to contain different fragrance components, it is possible to realize a thin film 10A in which the fragrance emitted changes with the passage of time. Further, if the plurality of holding layers 20 are configured to contain fragrance components having different concentrations, the intensity of fragrance can be adjusted over time by adjusting the concentration of the fragrance components contained in each holding layer 20. Is.
 また、第1面11Fを有する保持層20が抗菌成分を含有し、第2面11Rを有する保持層20が芳香成分を含有する構成であれば、被着体表面における細菌の増殖が抑えられるとともに、芳香が発生しやすくなる。すなわち、各成分がその機能に応じた位置の保持層20に含有されるため、各成分の効果が好適に発揮される。 Further, if the holding layer 20 having the first surface 11F contains an antibacterial component and the holding layer 20 having the second surface 11R contains an aromatic component, the growth of bacteria on the surface of the adherend can be suppressed. , Fragrance is likely to occur. That is, since each component is contained in the holding layer 20 at a position corresponding to its function, the effect of each component is preferably exhibited.
 図3は、第2形態の薄型フィルム10である薄型フィルム10Bの構造を示す。薄型フィルム10Bは、保持層20に加えて、拡散抑制層30を備えている。第2形態において、第1面11Fは保持層20の有する面であり、第2面11Rは拡散抑制層30の有する面である。すなわち、薄型フィルム10Bを被着体に貼り付けたとき、保持層20が被着体に接し、拡散抑制層30は、保持層20に対して被着体と反対側に位置する。 FIG. 3 shows the structure of the thin film 10B, which is the thin film 10 of the second form. The thin film 10B includes a diffusion suppressing layer 30 in addition to the holding layer 20. In the second form, the first surface 11F is the surface of the holding layer 20, and the second surface 11R is the surface of the diffusion suppressing layer 30. That is, when the thin film 10B is attached to the adherend, the holding layer 20 is in contact with the adherend, and the diffusion suppressing layer 30 is located on the side opposite to the adherend with respect to the holding layer 20.
 拡散抑制層30は、高分子材料を含み、機能成分を含まない。拡散抑制層30を構成する高分子材料としては、公知の材料が用いられる。例えば、拡散抑制層30を構成する高分子材料は、ポリエステル、ポリオレフィン、ポリアミド、ポリイミド、ポリビニルアルコール、ポリウレタン、ポリ酢酸ビニル、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、アクリル樹脂、ポリシロキサン類、セルロースやキチンやキトサン等の多糖類、カゼイン等の各種のたんぱく質、ゴム、これらの高分子化合物の誘導体、変性体、共重合体、混合物である。 The diffusion suppression layer 30 contains a polymer material and does not contain any functional component. A known material is used as the polymer material constituting the diffusion suppression layer 30. For example, the polymer materials constituting the diffusion suppression layer 30 include polyester, polyolefin, polyamide, polyimide, polyvinyl alcohol, polyurethane, polyvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polycarbonate, acrylic resin, polysiloxanes, cellulose and the like. Polysaccharides such as chitin and chitosan, various proteins such as casein, rubber, derivatives of these high molecular compounds, modified products, copolymers, and mixtures.
 拡散抑制層30は、保持層20が備える機能成分の外部への拡散を抑える機能、特に、薄型フィルム10Bに対して被着体と反対側への香料成分の拡散を抑える機能を有する。拡散抑制層30が設けられていることにより、被着体と反対側への機能成分の徐放性が高まる。すなわち、機能成分が香料成分である場合には、芳香の持続時間が長くなる。 The diffusion suppression layer 30 has a function of suppressing the diffusion of the functional component contained in the holding layer 20 to the outside, particularly a function of suppressing the diffusion of the fragrance component to the side opposite to the adherend with respect to the thin film 10B. By providing the diffusion suppression layer 30, the sustained release property of the functional component to the side opposite to the adherend is enhanced. That is, when the functional component is a fragrance component, the duration of the fragrance becomes long.
 拡散抑制層30の材料や厚さや密度によって、機能成分の徐放性の調整が可能である。例えば、拡散抑制層30の材料として、機能成分と親和性の低い材料を用いることで、機能成分の拡散がより抑えられ、機能成分の徐放性が高められる。例えば、機能成分が親水性である場合には、拡散抑制層30の材料として、疎水性の材料を用いればよい。また、拡散抑制層30の厚さや密度を大きくすることによっても、機能成分の徐放性を高めることができる。 The sustained release property of the functional component can be adjusted depending on the material, thickness and density of the diffusion suppression layer 30. For example, by using a material having a low affinity for the functional component as the material of the diffusion suppressing layer 30, the diffusion of the functional component is further suppressed and the sustained release property of the functional component is enhanced. For example, when the functional component is hydrophilic, a hydrophobic material may be used as the material for the diffusion suppression layer 30. Further, by increasing the thickness and density of the diffusion suppression layer 30, the sustained release property of the functional component can be enhanced.
 図4は、第3形態の薄型フィルム10である薄型フィルム10Cの構造を示す。薄型フィルム10Cは、保持層20に加えて、第2形態の拡散抑制層30である第1拡散抑制層30と、第2拡散抑制層31とを備えている。保持層20は、第1拡散抑制層30と第2拡散抑制層31とに挟まれている。第3形態において、第1面11Fは第2拡散抑制層31の有する面であり、第2面11Rは第1拡散抑制層30の有する面である。すなわち、薄型フィルム10Cを被着体に貼り付けたとき、第2拡散抑制層31が被着体に接し、第1拡散抑制層30は、保持層20に対して被着体と反対側に位置する。 FIG. 4 shows the structure of the thin film 10C, which is the thin film 10 of the third form. In addition to the holding layer 20, the thin film 10C includes a first diffusion suppressing layer 30 which is a diffusion suppressing layer 30 of the second form, and a second diffusion suppressing layer 31. The holding layer 20 is sandwiched between the first diffusion suppressing layer 30 and the second diffusion suppressing layer 31. In the third form, the first surface 11F is the surface of the second diffusion suppression layer 31, and the second surface 11R is the surface of the first diffusion suppression layer 30. That is, when the thin film 10C is attached to the adherend, the second diffusion suppressing layer 31 is in contact with the adherend, and the first diffusion suppressing layer 30 is located on the opposite side of the holding layer 20 from the adherend. To do.
 第2拡散抑制層31は、高分子材料を含み、機能成分を含まない。第2拡散抑制層31を構成する高分子材料としては、公知の材料が用いられる。例えば、第2拡散抑制層31を構成する高分子材料は、ポリエステル、ポリオレフィン、ポリアミド、ポリイミド、ポリビニルアルコール、ポリウレタン、ポリ酢酸ビニル、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、アクリル樹脂、ポリシロキサン類、セルロースやキチンやキトサン等の多糖類、カゼイン等の各種のたんぱく質、ゴム、これらの高分子化合物の誘導体、変性体、共重合体、混合物である。被着体が生体である場合には、第2拡散抑制層31を構成する高分子材料は生体適合性を有することが好ましい。 The second diffusion suppression layer 31 contains a polymer material and does not contain any functional component. A known material is used as the polymer material constituting the second diffusion suppression layer 31. For example, the polymer materials constituting the second diffusion suppression layer 31 include polyester, polyolefin, polyamide, polyimide, polyvinyl alcohol, polyurethane, polyvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polycarbonate, acrylic resin, and polysiloxanes. Polysaccharides such as cellulose, chitin and chitosan, various proteins such as casein, rubber, derivatives of these high molecular compounds, modified products, copolymers and mixtures. When the adherend is a living body, it is preferable that the polymer material constituting the second diffusion suppression layer 31 has biocompatibility.
 第2拡散抑制層31は、保持層20が備える機能成分が被着体に向けて拡散することを抑える機能を有する。また、第2拡散抑制層31が設けられていることにより、被着体が生体である場合には、被着体が機能成分から受ける刺激を低減できる。 The second diffusion suppressing layer 31 has a function of suppressing the functional components included in the holding layer 20 from diffusing toward the adherend. Further, by providing the second diffusion suppressing layer 31, when the adherend is a living body, the stimulation received by the adherend from the functional component can be reduced.
 被着体が生体、特に生体の皮膚である場合、第2拡散抑制層31は、体臭の原因成分を吸着する材料である体臭吸着剤を含有していてもよい。体臭吸着剤としては、例えば、メソポーラスシリカやナノポーラスシリカ等の多孔質シリカ、活性炭、ゼオライト等を用いることができる。これにより、薄型フィルム10Cが貼り付けられている部分の付近で、体臭の発生が抑えられる。 When the adherend is a living body, particularly the skin of a living body, the second diffusion suppressing layer 31 may contain a body odor adsorbent which is a material for adsorbing a component causing body odor. As the body odor adsorbent, for example, porous silica such as mesoporous silica or nanoporous silica, activated carbon, zeolite and the like can be used. As a result, the generation of body odor is suppressed in the vicinity of the portion where the thin film 10C is attached.
 第2形態および第3形態において、拡散抑制層30,31は、複数の層から構成されていてもよい。また、被着体に向けた機能成分の拡散を抑えたい場合には、薄型フィルム10は、第1面11Fを有する拡散抑制層31と、第2面11Rを有する保持層20とを備えていてもよい。また、第2面11Rを有する拡散抑制層30は、金属膜であってもよい。 In the second form and the third form, the diffusion suppression layers 30 and 31 may be composed of a plurality of layers. Further, when it is desired to suppress the diffusion of the functional component toward the adherend, the thin film 10 includes a diffusion suppressing layer 31 having a first surface 11F and a holding layer 20 having a second surface 11R. May be good. Further, the diffusion suppression layer 30 having the second surface 11R may be a metal film.
 薄型フィルム10が保持層20と拡散抑制層とを備える場合、拡散抑制層も含めた薄型フィルム10の全体の質量に対する機能成分の総質量の割合が、50ppm以上30%以下であればよい。 When the thin film 10 includes the holding layer 20 and the diffusion suppressing layer, the ratio of the total mass of the functional components to the total mass of the thin film 10 including the diffusion suppressing layer may be 50 ppm or more and 30% or less.
 図5は、第4形態の薄型フィルム10である薄型フィルム10Dの構造を示す。薄型フィルム10Dは、第2面11Rに凹凸構造40を有する。図5は、第1形態の薄型フィルム10Aに対応する層構成、すなわち、保持層のみを備える構成が適用された場合の薄型フィルム10Dの構造を示す。この場合、薄型フィルム10Dは、第2面11Rである表面に凹凸構造40を有する保持層21を備えている。保持層21の材料は第1形態の保持層20の材料と同様である。 FIG. 5 shows the structure of the thin film 10D, which is the thin film 10 of the fourth form. The thin film 10D has an uneven structure 40 on the second surface 11R. FIG. 5 shows the structure of the thin film 10D when the layer structure corresponding to the thin film 10A of the first form, that is, the structure including only the holding layer is applied. In this case, the thin film 10D includes a holding layer 21 having an uneven structure 40 on the surface of the second surface 11R. The material of the holding layer 21 is the same as the material of the holding layer 20 of the first form.

 第2面11Rに凹凸構造40が設けられていることにより、第2面11Rの表面積が大きくなる結果、第2面11Rからの機能成分の拡散が促進される。したがって、機能成分の徐放性の程度、特に香料成分の徐放性の程度を、より細かに調整することができる。例えば、凹凸構造を設けない第1形態では香料成分の徐放性が所望の程度よりも小さく、凹凸構造を設けない第2形態では香料成分の徐放性が所望の程度よりも大きい場合、第2形態の層構成を適用した第4形態、すなわち、凹凸構造が設けられた拡散抑制層を有する薄型フィルム10Dであれば、所望の程度により近い香料成分の徐放性が得られる。 Since the uneven structure 40 is provided on the second surface 11R, the surface area of the second surface 11R is increased, and as a result, the diffusion of the functional component from the second surface 11R is promoted. Therefore, the degree of sustained release of the functional ingredient, particularly the degree of sustained release of the fragrance component can be adjusted more finely. For example, in the first form without the uneven structure, the sustained release property of the fragrance component is smaller than the desired degree, and in the second form without the uneven structure, the sustained release property of the fragrance component is larger than the desired degree. In the fourth form to which the two forms of layer structure are applied, that is, the thin film 10D having a diffusion suppressing layer provided with an uneven structure, sustained release of the fragrance component closer to a desired degree can be obtained.
 なお、凹凸構造40は、第2面11Rの全面に設けられていなくてもよい。凹凸構造40を設ける領域の大きさの調整によって、機能成分の徐放性をより細かく調整することも可能である。 The uneven structure 40 does not have to be provided on the entire surface of the second surface 11R. By adjusting the size of the region where the concave-convex structure 40 is provided, it is also possible to finely adjust the sustained release property of the functional component.
 図6は、第5形態の薄型フィルム10である薄型フィルム10Eの構造を示す。薄型フィルム10Eは、1以上の層を貫通する複数の貫通孔41を有する。図6は、第1形態の薄型フィルム10Aに対応する層構成、すなわち、保持層のみを備える構成が適用された場合の薄型フィルム10Eの構造を示す。この場合、薄型フィルム10Eは、第1面11Fから第2面11Rまで貫通する貫通孔41を有する保持層22を備えている。保持層22の材料は第1形態の保持層20の材料と同様である。 FIG. 6 shows the structure of the thin film 10E, which is the thin film 10 of the fifth form. The thin film 10E has a plurality of through holes 41 penetrating one or more layers. FIG. 6 shows the structure of the thin film 10E when the layer structure corresponding to the thin film 10A of the first form, that is, the structure including only the holding layer is applied. In this case, the thin film 10E includes a holding layer 22 having a through hole 41 penetrating from the first surface 11F to the second surface 11R. The material of the holding layer 22 is the same as the material of the holding layer 20 of the first form.
 貫通孔41が設けられていることにより、保持層22から機能成分が揮発して薄型フィルム10Eの外部に出やすくなる。これによっても、機能成分の拡散、特に香料成分の拡散が促進されるため、香料成分の徐放性の程度を、より細かに調整することができる。貫通孔41の数や分布の調整によって、香料成分の徐放性をより細かく調整することも可能である。 Since the through hole 41 is provided, the functional component volatilizes from the holding layer 22 and easily goes out of the thin film 10E. This also promotes the diffusion of the functional component, particularly the diffusion of the fragrance component, so that the degree of sustained release of the fragrance component can be finely adjusted. By adjusting the number and distribution of the through holes 41, it is possible to finely adjust the sustained release property of the fragrance component.
 第5形態には、第2形態の薄型フィルム10Bの層構成や第3形態の薄型フィルム10Cの層構成が適用されてもよい。これらの場合、貫通孔41は第1面11Fから第2面11Rまでを貫通していてもよいし、一部の層を貫通していてもよい。例えば、貫通孔41は、第2面11Rを有する拡散抑制層のみを貫通していてもよい。香料成分の拡散の促進のためには、第2面11Rを有する層に貫通孔41が設けられていることが好ましい。 The layer structure of the thin film 10B of the second form and the layer structure of the thin film 10C of the third form may be applied to the fifth form. In these cases, the through hole 41 may penetrate from the first surface 11F to the second surface 11R, or may penetrate a part of the layers. For example, the through hole 41 may penetrate only the diffusion suppression layer having the second surface 11R. In order to promote the diffusion of the fragrance component, it is preferable that the layer having the second surface 11R is provided with the through hole 41.
 図7は、第6形態の薄型フィルム10である薄型フィルム10Fの構造を示す。薄型フィルム10Fは、カプセル42を含有する保持層23を備えており、カプセル42の内部に機能成分が保持されている。カプセル42はマイクロカプセルもしくはナノカプセルである。 FIG. 7 shows the structure of the thin film 10F, which is the thin film 10 of the sixth form. The thin film 10F includes a holding layer 23 containing the capsule 42, and the functional component is held inside the capsule 42. Capsules 42 are microcapsules or nanocapsules.
 保持層23において、複数のカプセル42は、高分子材料中に分散している。保持層23を構成する高分子材料としては、第1形態の保持層20の材料として例示した高分子材料が用いられる。機能成分としては、第1形態にて例示した物質のうち、カプセル42への包摂が可能な物質が用いられる。カプセル42は、公知のマイクロカプセルやナノカプセルの材料から形成されればよい。 In the holding layer 23, the plurality of capsules 42 are dispersed in the polymer material. As the polymer material constituting the holding layer 23, the polymer material exemplified as the material of the holding layer 20 of the first form is used. As the functional component, among the substances exemplified in the first form, a substance that can be included in the capsule 42 is used. The capsule 42 may be formed from a known microcapsule or nanocapsule material.
 保持層23が、カプセル42に包摂された状態で機能成分を保持することにより、機能成分の徐放性が高められる。なお、カプセル42への包摂に代えて、機能成分は担体に担持されていてもよい。 By retaining the functional component in a state where the holding layer 23 is encapsulated in the capsule 42, the sustained release property of the functional component is enhanced. Instead of inclusion in the capsule 42, the functional component may be supported on a carrier.
 第6形態は、第2~第5形態と組み合わされてもよい。すなわち、第2~第5形態における保持層が、機能成分が包摂されたカプセル42を含有する保持層とされてもよい。
 図8は、第7形態の薄型フィルム10である薄型フィルム10Gの構造を示す。薄型フィルム10Gは、高分子材料に混合された機能成分と共に拡散阻害物質43,44を含有する保持層24を備えている。
The sixth form may be combined with the second to fifth forms. That is, the holding layer in the second to fifth forms may be a holding layer containing the capsule 42 in which the functional component is included.
FIG. 8 shows the structure of the thin film 10G, which is the thin film 10 of the seventh form. The thin film 10G includes a holding layer 24 containing diffusion inhibitors 43 and 44 together with functional components mixed with the polymer material.
 拡散阻害物質は、機能成分が薄型フィルム10Gの外部へ出ることを阻害する物質である。例えば、拡散阻害物質は、薄型フィルム10Gの外部へ向けた機能成分の経路を塞ぐことにより、機能成分の拡散、特に香料成分の拡散を抑える。拡散阻害物質は、例えば、層状の無機化合物、無機化合物粒子、有機化合物粒子、有機無機ハイブリッド材料等である。図8では、保持層24が、層状の拡散阻害物質43と、粒子状の拡散阻害物質44とを含有する構成を例示しているが、拡散阻害物質は層状や粒子状とは異なる形状を有していてもよい。また、保持層24が含む拡散阻害物質は1種類であってもよいし、2種類以上であってもよい。 The diffusion inhibitor is a substance that inhibits the functional component from leaving the thin film 10G. For example, the diffusion inhibitor suppresses the diffusion of the functional component, particularly the diffusion of the fragrance component, by blocking the path of the functional component toward the outside of the thin film 10G. The diffusion inhibitor is, for example, a layered inorganic compound, inorganic compound particles, organic compound particles, an organic-inorganic hybrid material, or the like. FIG. 8 illustrates a configuration in which the holding layer 24 contains a layered diffusion inhibitor 43 and a particulate diffusion inhibitor 44, but the diffusion inhibitor has a shape different from that of the layered or particulate. You may be doing it. Further, the diffusion inhibitor contained in the holding layer 24 may be one kind or two or more kinds.
 層状の無機化合物としては、マイカ、モンモリロナイト、サポナイト、ヘクトライト、フルオロヘクトライト等のスメクタイト族、カオリナイト等のカオリン族、マカディアイト、ケニヤアイト、カネマイト等の粘土鉱物の細片を用いることができる。こうした粘土鉱物は、層状ケイ酸塩鉱物を主成分とする。層状の無機化合物は、層間の有機修飾を行うことにより、有機無機ハイブリッド材料として使用することも可能である。その他、有機無機ハイブリッド材料としては、各種のシリコーンや各種のシランカップリング剤を用いることができる。 As the layered inorganic compound, fine pieces of clay minerals such as mica, montmorillonite, saponite, hectorite, fluorohectorite and other smectites, kaolinite and other kaolins, micadiaite, kenyaite and kanemite can be used. These clay minerals are mainly composed of layered silicate minerals. The layered inorganic compound can also be used as an organic-inorganic hybrid material by performing organic modification between layers. In addition, as the organic-inorganic hybrid material, various silicones and various silane coupling agents can be used.
 無機化合物粒子を構成する無機材料としては、Si、Al、Cu、Ag等の金属やそれらの酸化物を用いることができる。有機化合物粒子を構成する有機材料としては、ポリエステル、ポリプロピレン、ポリエチレン、ポリスチレン、ポリウレタン、アクリル樹脂やそれらの共重合体やブレンド樹脂等を用いることができる。なお、粒子の形状は特に限定されない。 As the inorganic material constituting the inorganic compound particles, metals such as Si, Al, Cu, and Ag and oxides thereof can be used. As the organic material constituting the organic compound particles, polyester, polypropylene, polyethylene, polystyrene, polyurethane, acrylic resin, copolymers thereof, blended resin and the like can be used. The shape of the particles is not particularly limited.
 保持層23を構成する高分子材料および機能成分としては、第1形態の保持層20の材料として例示した高分子材料および機能成分が用いられる。
 保持層23が拡散阻害物質を含有していることによって、機能成分の徐放性を高めることができる。含有させる拡散阻害物質の種類や含有量の調整によって、機能成分の徐放性の程度を調整することができる。
As the polymer material and the functional component constituting the holding layer 23, the polymer material and the functional component exemplified as the material of the holding layer 20 of the first form are used.
Since the retention layer 23 contains a diffusion inhibitor, the sustained release property of the functional component can be enhanced. The degree of sustained release of the functional component can be adjusted by adjusting the type and content of the diffusion inhibitor to be contained.
 また、保持層23が拡散阻害物質を含有していることによって、薄型フィルム10Gの閉塞率を高めることもできる。含有させる拡散阻害物質の種類や含有量の調整によって、閉塞率の大きさを調整することができる。 Further, since the holding layer 23 contains a diffusion inhibitor, the blockage rate of the thin film 10G can be increased. The magnitude of the occlusion rate can be adjusted by adjusting the type and content of the diffusion inhibitor to be contained.
 第7形態は、第2~第6形態と組み合わされてもよい。すなわち、第2~第6形態における保持層が、拡散阻害物質を含有する保持層とされてもよい。また、薄型フィルム10が拡散抑制層を備える場合、保持層に代えて、あるいは、保持層に加えて、拡散抑制層が拡散阻害物質を含有していてもよい。こうした構成によっても、機能成分の徐放性を高めること、および、薄型フィルム10の閉塞率を高めることが可能である。 The seventh form may be combined with the second to sixth forms. That is, the retention layer in the second to sixth forms may be a retention layer containing a diffusion inhibitor. When the thin film 10 includes a diffusion inhibitory layer, the diffusion inhibitory layer may contain a diffusion inhibitor instead of the retention layer or in addition to the retention layer. With such a configuration, it is possible to increase the sustained release property of the functional component and increase the blockage rate of the thin film 10.
 第1~第7形態のいずれにおいても、保持層あるいは拡散抑制層は、添加剤を含んでいてもよい。添加剤は、例えば、薄型フィルム10の光学特性を調整するための高屈折率材料、低屈折率材料、光吸収剤、色素や、薄型フィルム10の濡れ性を調整するための改質剤、導電性材料、化粧料成分、薬効成分等である。薄型フィルム10に含有させる添加剤は、薄型フィルム10において発現させたい機能に応じて選択されればよい。 In any of the first to seventh forms, the holding layer or the diffusion suppressing layer may contain an additive. The additives include, for example, a high refractive index material, a low refractive index material, a light absorber, a dye for adjusting the optical characteristics of the thin film 10, a modifier for adjusting the wettability of the thin film 10, and conductivity. Sexual materials, cosmetic ingredients, medicinal ingredients, etc. The additive contained in the thin film 10 may be selected according to the function to be expressed in the thin film 10.
 第1~第7形態において、薄型フィルム10が備える各層は、公知の薄膜形成方法によって形成される。例えば、溶融した材料を押し出して薄膜状に成形する溶融押出法や、材料の溶液を薄膜状に基材に塗布した後に溶媒を蒸発させる溶液キャスト法を用いることができる。各層の形成方法は、各層の材料に応じて選択されればよい。 In the first to seventh forms, each layer included in the thin film 10 is formed by a known thin film forming method. For example, a melt extrusion method in which a molten material is extruded to form a thin film, or a solution casting method in which a solution of the material is applied to a base material in a thin film and then the solvent is evaporated can be used. The method for forming each layer may be selected according to the material of each layer.
 例えば、溶液キャスト法を用いる場合、保持層の材料を適宜の溶媒に溶解もしくは分散させることにより塗液を生成し、塗液を樹脂等からなる基材に塗布して塗膜を形成する。塗膜が乾燥により固化されることによって、保持層が形成される。塗布方法としては、例えば、ダイレクトグラビア、リバースグラビア、小径リバースグラビア、マイヤーコート、ダイ、カーテン、スプレー、スピンコート、スクリーン印刷、コンマ、ナイフ、グラビアオフセット、ロールコート等の各種のコーティング方法が使用可能である。 For example, when the solution casting method is used, a coating liquid is generated by dissolving or dispersing the material of the holding layer in an appropriate solvent, and the coating liquid is applied to a base material made of a resin or the like to form a coating film. A retaining layer is formed by solidifying the coating film by drying. As the coating method, for example, various coating methods such as direct gravure, reverse gravure, small diameter reverse gravure, Meyer coat, die, curtain, spray, spin coat, screen printing, comma, knife, gravure offset, roll coat can be used. Is.
 拡散抑制層も同様の方法によって形成される。薄型フィルム10が複数の層を有する場合、塗液の塗布と塗膜の乾燥とが、層ごとに繰り返されて、積層体が形成される。
 第4形態の凹凸構造40は、凹凸の形成された基材上に塗膜を形成することや、塗膜の乾燥前もしくは後に凹凸の形成された版を膜の表面に押し付けることや、塗膜の乾燥後に膜表面に傷をつける等の表面加工を行うことによって形成できる。
The diffusion suppression layer is also formed by the same method. When the thin film 10 has a plurality of layers, the application of the coating liquid and the drying of the coating film are repeated for each layer to form a laminated body.
The concavo-convex structure 40 of the fourth form forms a coating film on a substrate on which the concavo-convex shape is formed, presses a plate on which the concavo-convex shape is formed before or after drying the coating film against the surface of the film, or coats the coating film. It can be formed by performing surface treatment such as scratching the film surface after drying.
 第5形態の貫通孔41は、塗膜の乾燥後に穴あけ加工を行うことによって形成できる。薄型フィルム10が複数の層を有する場合、各層の積層後に薄型フィルム10の全体に対して穴あけ加工が行われてフィルム全体を貫通する貫通孔41が形成されてもよいし、各層の積層前に一部の層に対して穴あけ加工が行われて、一部の層を貫通する貫通孔41が形成されてもよい。 The through hole 41 of the fifth form can be formed by performing a hole drilling process after the coating film is dried. When the thin film 10 has a plurality of layers, a hole may be formed in the entire thin film 10 after laminating each layer to form a through hole 41 penetrating the entire film, or before laminating each layer. A hole may be drilled in a part of the layers to form a through hole 41 penetrating the part of the layers.

The transfer sheet is used when the thin film 10 is attached to an adherend.
As shown in FIG. 9, the transfer sheet 50 includes a thin film 10 and a supporting base material 51 that supports the thin film 10. The second surface 11R of the thin film 10 is in contact with the support base material 51.
 支持基材51は、薄型フィルム10の保管時や、薄型フィルム10の使用に際して被着体上まで薄型フィルム10を移動させるときに、薄型フィルム10の変形を抑える機能を有する。支持基材51に支持されていることにより、薄型フィルム10が取り扱いやすくなる。 The support base material 51 has a function of suppressing deformation of the thin film 10 when the thin film 10 is stored or when the thin film 10 is moved onto the adherend when the thin film 10 is used. By being supported by the supporting base material 51, the thin film 10 becomes easy to handle.
 支持基材51の材料は特に限定されない。支持基材51は、例えば、高分子フィルム、織物、編物、不織布、および、紙のいずれかであることが好ましい。
 高分子フィルムの材料としては、ポリエステル、ポリオレフィン、ポリアミド、ポリイミド、ポリビニルアルコール、ポリウレタン、ポリ酢酸ビニル、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、アクリル樹脂、ポリシロキサン類、セルロース、カゼイン等の各種のたんぱく質、ゴム、これらの高分子化合物の誘導体、変性体、共重合体、混合物が挙げられる。支持基材51として用いられる高分子フィルムは、エンボス加工、穴あけ加工、発泡等による多孔質化等の加工が施されたフィルムであってもよい。
The material of the support base material 51 is not particularly limited. The supporting base material 51 is preferably, for example, a polymer film, a woven fabric, a knitted fabric, a non-woven fabric, or paper.
Materials for polymer films include various proteins such as polyester, polyolefin, polyamide, polyimide, polyvinyl alcohol, polyurethane, polyvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polycarbonate, acrylic resin, polysiloxanes, cellulose, and casein. , Rubber, derivatives of these polymer compounds, modified products, copolymers, mixtures and the like. The polymer film used as the supporting base material 51 may be a film that has been subjected to processing such as embossing, drilling, and porosity by foaming.
 織物、編物、および、不織布は、天然繊維もしくは化学繊維から構成される。天然繊維としては、綿、麻、パルプ、毛、絹等を用いることができる。化学繊維としては、ポリエステル、ポリオレフィン、キュプラ、レーヨン、リヨセル、アセテート、ジアセテート、ナイロン、アラミド、アクリル等からなる繊維を用いることができる。また、支持基材51は、天然繊維と化学繊維とが混合された繊維材料から構成されていてもよい。こうした繊維材料からなる支持基材51においては、エンボス加工、穴あけ加工、発泡等による繊維の多孔質化等の加工が施されていてもよい。 Woven fabrics, knitted fabrics, and non-woven fabrics are composed of natural fibers or chemical fibers. As the natural fiber, cotton, linen, pulp, hair, silk and the like can be used. As the chemical fiber, a fiber made of polyester, polyolefin, cupra, rayon, lyocell, acetate, diacetate, nylon, aramid, acrylic or the like can be used. Further, the support base material 51 may be composed of a fiber material in which natural fibers and chemical fibers are mixed. The supporting base material 51 made of such a fiber material may be subjected to processing such as embossing, drilling, foaming, or the like to make the fiber porous.
 支持基材51が繊維材料からなる場合、支持基材51の目付けは、3g/m以上200g/m以下であることが好ましく、10g/m以上100g/m以下であることがより好ましい。支持基材51の目付けが上記下限値以上であれば、静電気や気流に起因して縒れ等の変形が生じ難くなる程度の剛性を支持基材51が有するため、薄型フィルム10が取り扱いやすくなる。また、支持基材51の目付けが上記上限値以下であれば、支持基材51において繊維が詰まりすぎないため、転写シート50の使用に際して支持基材51を湿潤させて薄型フィルム10から剥離する転写方法を用いる場合に、支持基材51の吸液が円滑に進み、転写を好適に行うことができる。 When the support base material 51 is made of a fiber material, the basis weight of the support base material 51 is preferably 3 g / m 2 or more and 200 g / m 2 or less, and more preferably 10 g / m 2 or more and 100 g / m 2 or less. preferable. When the basis weight of the support base material 51 is equal to or higher than the above lower limit value, the support base material 51 has a rigidity sufficient to prevent deformation such as twisting due to static electricity or air flow, so that the thin film 10 can be easily handled. .. Further, if the basis weight of the support base material 51 is not more than the above upper limit value, the fibers are not excessively clogged in the support base material 51. When the method is used, the liquid absorption of the support base material 51 proceeds smoothly, and the transfer can be preferably performed.
 また、転写シート50は、薄型フィルム10の第1面11Fを覆う保護層を備えていてもよい。保護層を備えることにより、薄型フィルム10の保管時において、薄型フィルム10が保護される。保護層としては、支持基材51として例示した上述の各種の基材を用いることができる。なお、保護層と支持基材51との材料は一致していてもよいし、異なっていてもよい。 Further, the transfer sheet 50 may be provided with a protective layer that covers the first surface 11F of the thin film 10. By providing the protective layer, the thin film 10 is protected during storage of the thin film 10. As the protective layer, the above-mentioned various base materials exemplified as the support base material 51 can be used. The materials of the protective layer and the supporting base material 51 may be the same or different.
 なお、平面視における薄型フィルム10および転写シート50の外形形状は、特に限定されない。薄型フィルム10および転写シート50の外形形状は、例えば、矩形等の多角形形状、円形状、楕円形状、これら以外の直線や曲線で囲まれた形状等である。平面視にて、薄型フィルム10と支持基材51の形状は一致していてもよいし、支持基材51は薄型フィルム10よりも大きくてもよい。 The outer shapes of the thin film 10 and the transfer sheet 50 in a plan view are not particularly limited. The outer shape of the thin film 10 and the transfer sheet 50 is, for example, a polygonal shape such as a rectangle, a circular shape, an elliptical shape, or a shape surrounded by straight lines or curves other than these. In a plan view, the shapes of the thin film 10 and the support base material 51 may be the same, and the support base material 51 may be larger than the thin film 10.
 転写シート50は、成膜用の基材上に形成された薄型フィルム10が支持基材51上に転写されることによって形成されてもよいし、支持基材51上に薄型フィルム10が成膜されることによって形成されてもよい。成膜用の基材から支持基材51への薄型フィルム10の転写方法としては、吸引による剥離を利用する方法や犠牲膜を利用する方法等、公知の転写方法が用いられればよい。 The transfer sheet 50 may be formed by transferring the thin film 10 formed on the base material for film formation onto the support base material 51, or the thin film 10 may be formed on the support base material 51. It may be formed by being done. As a method for transferring the thin film 10 from the base material for film formation to the supporting base material 51, a known transfer method such as a method using peeling by suction or a method using a sacrificial film may be used.
 転写シート50の使用に際しては、まず、被着体と薄型フィルム10の第1面11Fとが接するように、被着体上に転写シート50が配置される。そして、薄型フィルム10から支持基材51が剥離される。これにより、薄型フィルム10が被着体に転写される。 When using the transfer sheet 50, first, the transfer sheet 50 is arranged on the adherend so that the adherend and the first surface 11F of the thin film 10 are in contact with each other. Then, the supporting base material 51 is peeled off from the thin film 10. As a result, the thin film 10 is transferred to the adherend.
 転写シート50を貼り付ける前の被着体の表面や、転写シート50を貼り付けた後の支持基材51上に、水やローション等の液状体が供給され、転写シート50に液状体を浸透させることで、支持基材51と薄型フィルム10との剥離が促進されてもよい。 A liquid material such as water or lotion is supplied onto the surface of the adherend before the transfer sheet 50 is attached and the support base material 51 after the transfer sheet 50 is attached, and the liquid material permeates the transfer sheet 50. By doing so, the peeling of the support base material 51 and the thin film 10 may be promoted.
 本実施形態の薄型フィルム10は、香料成分および抗菌成分の少なくとも一方を含んでいるため、薄型フィルム10を被着体に貼り付けて用いることによって、香料成分に起因した芳香が得られる効果や、抗菌成分によって被着体からの臭いの発生が抑えられる効果が得られる。そして、香料成分や抗菌成分が薄型フィルム10に保持されているため、芳香や消臭のための従来の液状の製品と比較して、香料成分や抗菌成分による効果の持続時間が長く得られる。 Since the thin film 10 of the present embodiment contains at least one of a fragrance component and an antibacterial component, the effect of obtaining the fragrance caused by the fragrance component and the effect of using the thin film 10 by attaching it to the adherend can be obtained. The antibacterial component has the effect of suppressing the generation of odor from the adherend. Since the fragrance component and the antibacterial component are retained in the thin film 10, the duration of the effect of the fragrance component and the antibacterial component can be obtained longer than that of the conventional liquid product for fragrance and deodorization.
 なお、被着体および薄型フィルム10の用途は特に限定されない。従来の液状の製品では、上述のように汗の発生や衣服との擦れ等によって、成分を皮膚上に長時間保持させることが困難であったことに対し、薄型フィルム10は、機能成分を保持した状態で皮膚に長時間貼り付けておくことが可能である。したがって、被着体が皮膚であると、従来の液状の製品と比較して、効果の持続時間を延ばす効果が特に高く得られる。 The use of the adherend and the thin film 10 is not particularly limited. In the conventional liquid product, it was difficult to keep the component on the skin for a long time due to the generation of sweat, rubbing against clothes, etc. as described above, whereas the thin film 10 retains the functional component. It is possible to stick it on the skin for a long time in this state. Therefore, when the adherend is skin, the effect of prolonging the duration of the effect is particularly high as compared with the conventional liquid product.
 [転写シート収容体]

[Transfer sheet container]
FIG. 10 shows an container in which the transfer sheet 50 is housed. The transfer sheet accommodating body 60 includes a transfer sheet 50 having a protective layer and a packaging body 61 accommodating the transfer sheet 50.
 転写シート50の使用前に薄型フィルム10の機能成分が外部に拡散することを抑えるために、包装体61は、密封可能に構成されていることが好ましい。
 包装体61は、例えば、高分子フィルムから形成された袋状を有する。高分子フィルムとしては、例えば、ポリオレフィン、ポリエステル、ポリアクリロニトリル、ナイロン等からなる単層または複数の層からなるフィルムが用いられる。さらに、包装体61においては、高分子フィルムに有機物および無機物の少なくとも一方からなるガスバリア層が積層されていてもよい。ガスバリア層が設けられることによって、薄型フィルム10の機能成分が揮発することが抑えられる。また、包装体61の材料には、機能成分を吸着しにくい材料が用いられることが好ましい。
In order to prevent the functional components of the thin film 10 from diffusing to the outside before the transfer sheet 50 is used, the package 61 is preferably configured so as to be hermetically sealed.
The package 61 has, for example, a bag shape formed of a polymer film. As the polymer film, for example, a film composed of a single layer or a plurality of layers made of polyolefin, polyester, polyacrylonitrile, nylon or the like is used. Further, in the package 61, a gas barrier layer made of at least one of an organic substance and an inorganic substance may be laminated on the polymer film. By providing the gas barrier layer, it is possible to prevent the functional components of the thin film 10 from volatilizing. Further, as the material of the package 61, it is preferable to use a material that does not easily adsorb functional components.

A retaining layer was formed by heating the coating film in an oven to dry and solidify it. The heating temperature at the time of drying the coating film was 100 ° C., and the heating time was 2 minutes.
 次いで、酢酸エチルに、ポリ-DL-乳酸(武蔵野化学研究所社製)を、溶液中の固形分が10%となるように溶解することにより、拡散抑制層の形成のための塗液を生成した。使用したポリ-DL-乳酸の重量平均分子量は10万である。 Next, poly-DL-lactic acid (manufactured by Musashino Chemical Laboratory Co., Ltd.) was dissolved in ethyl acetate so that the solid content in the solution was 10%, thereby forming a coating liquid for forming a diffusion inhibitory layer. did. The weight average molecular weight of the poly-DL-lactic acid used is 100,000.
 上記拡散抑制層の形成のための塗液を、成膜用基材上の保持層の上に、ワイヤーバーを用いて塗布し、塗膜を形成した。塗膜をオーブンで加熱して乾燥・固化させることにより、拡散抑制層を形成した。塗膜の乾燥時の加熱温度は90℃、加熱時間は2分とした。 The coating liquid for forming the diffusion suppression layer was applied onto the holding layer on the film-forming substrate using a wire bar to form a coating film. A diffusion inhibitory layer was formed by heating the coating film in an oven to dry and solidify it. The heating temperature at the time of drying the coating film was 90 ° C., and the heating time was 2 minutes.
 以上により、成膜用基材上に、保持層と拡散抑制層とを備える薄型フィルムを形成した。当該薄型フィルムは、第2形態の薄型フィルムに対応する。
 次いで、成膜用基材上の薄型フィルムに支持基材を重ね合わせ、成膜用基材と薄型フィルムと支持基材との積層体を成膜用基材の位置する側からゴムローラーで押圧しつつ、成膜用基材を剥離した。支持基材としては、パルプ系の繊維から構成された不織布を用いた。支持基材の目付けは、35g/mである。以上により、転写シートを形成した。
As described above, a thin film having a holding layer and a diffusion suppressing layer was formed on the film-forming substrate. The thin film corresponds to the thin film of the second form.
Next, the supporting base material is superposed on the thin film on the film forming base material, and the laminate of the film forming base material, the thin film, and the supporting base material is pressed by a rubber roller from the side where the film forming base material is located. While doing so, the film-forming substrate was peeled off. As the supporting base material, a non-woven fabric composed of pulp-based fibers was used. The basis weight of the supporting base material is 35 g / m 2 . From the above, a transfer sheet was formed.

 実施例1~4および比較例1~3の各々について、5つずつサンプルを用意した。被着体としてのヒトの皮膚に、500μlの水を供給し、供給した水を指で軽く引き伸ばした。その後、サンプルの転写シートを、薄型フィルムが皮膚に接するように、皮膚上に配置した。次いで、支持基材の上から、3秒間、指でサンプルを押圧した。そして、サンプルの端部から、支持基材を指で剥離した。これにより、皮膚に薄型フィルムが貼り付けられた。
<Evaluation method>
(Aroma evaluation)
Five samples were prepared for each of Examples 1 to 4 and Comparative Examples 1 to 3. 500 μl of water was supplied to human skin as an adherend, and the supplied water was lightly stretched with a finger. The sample transfer sheet was then placed on the skin so that the thin film was in contact with the skin. Then, the sample was pressed with a finger from above the supporting base material for 3 seconds. Then, the supporting base material was peeled off from the end of the sample with a finger. As a result, the thin film was attached to the skin.
 皮膚上の薄型フィルムの表面と直交する方向に薄型フィルムから10cm離れた位置から、香気を知覚できるかを判定した。判定は、薄型フィルムを貼り付けてから1時間経過後と6時間経過後との各々について判定した。1時間経過後と6時間経過後との各々について、5つのサンプルのすべてについて香気を知覚できた場合を「〇」、3つもしくは4つのサンプルについて香気を知覚できた場合を「△」、香気を知覚できたサンプルが2つ以下であった場合を「×」とした。 It was determined whether the aroma could be perceived from a position 10 cm away from the thin film in the direction orthogonal to the surface of the thin film on the skin. Judgment was made for each of 1 hour and 6 hours after the thin film was attached. For each of 1 hour and 6 hours, if the aroma can be perceived for all 5 samples, "○", and if the aroma can be perceived for 3 or 4 samples, "△", the aroma. The case where the number of samples that could perceive was 2 or less was defined as "x".
 (転写性)
 実施例1~4および比較例1~3の各々について、5つずつサンプルを用意し、香気評価と同様に、皮膚に薄型フィルムを貼り付けた。薄型フィルムを貼り付けてから1時間経過後に、皮膚上の薄型フィルムを目視によって観察し、薄型フィルムに欠け、破れ、皺、縒れのいずれかの変形が生じているかを判定した。5つのサンプルのすべてにおいて変形が生じていない場合を「〇」、3つもしくは4つのサンプルにおいて変形が生じていない場合を「△」、変形が生じていないサンプルが2つ以下であった場合を「×」とした。
(Transcribability)
Five samples were prepared for each of Examples 1 to 4 and Comparative Examples 1 to 3, and a thin film was attached to the skin in the same manner as in the aroma evaluation. One hour after the thin film was applied, the thin film on the skin was visually observed to determine whether the thin film was chipped, torn, wrinkled, or twisted. "○" when all five samples are not deformed, "△" when three or four samples are not deformed, and two or less samples without deformation. It was set as "x".
 (貼付感)
 実施例1~4および比較例1~3の各々について、5つずつサンプルを用意し、香気評価と同様に、皮膚に薄型フィルムを貼り付けた。薄型フィルムを貼り付けてから1時間経過後に、薄型フィルムの貼付箇所に蒸れや突っ張り感等の違和感が生じているかを判定した。5つのサンプルのすべてについて違和感が生じていない場合を「〇」、3つもしくは4つのサンプルについて違和感が生じていない場合を「△」、違和感が生じていないサンプルが2つ以下であった場合を「×」とした。
(A feeling of sticking)
Five samples were prepared for each of Examples 1 to 4 and Comparative Examples 1 to 3, and a thin film was attached to the skin in the same manner as in the aroma evaluation. One hour after the thin film was attached, it was determined whether or not the thin film had a feeling of strangeness such as stuffiness or tension at the place where the thin film was attached. If there is no discomfort in all five samples, "○", if there is no discomfort in three or four samples, "△", and if there are two or less samples without discomfort. It was set as "x".

 表1が示すように、香料成分を含んでいる実施例1~4、比較例1,2では、少なくとも薄型フィルムの貼付の1時間経過後には、香気が良好に知覚されている。したがって、薄型フィルムが香料成分を含むことによって、薄型フィルムに芳香を放つ機能が付与されることが示された。
Figure JPOXMLDOC01-appb-T000001
As shown in Table 1, in Examples 1 to 4 and Comparative Examples 1 and 2 containing the fragrance component, the fragrance was well perceived at least after 1 hour of application of the thin film. Therefore, it was shown that the thin film contains a fragrance component to impart a function of emitting a fragrance to the thin film.
 一方で、単位面積当たりの質量が5.0g/m超える比較例1では、その厚さに起因して閉塞率が80%を超えている。そのため、保持層のなかで被着体の付近に位置する香料成分が薄型フィルムの外部まで拡散されず、薄型フィルムの貼付の6時間経過後には香気が知覚され難くなっている。また、比較例1では、皮膚上の薄型フィルムに皺が多く確認され、転写性の評価が悪かった。このことは、薄型フィルムの厚さが大きいために薄型フィルムと皮膚との密着性が低くなることに因ると考えられる。また、比較例1では、閉塞率が高いことに起因して、薄型フィルムの貼付による蒸れ等の違和感が生じやすく、貼付感の評価も悪かった。 On the other hand, in Comparative Example 1 in which the mass per unit area exceeds 5.0 g / m 2 , the blockage rate exceeds 80% due to the thickness. Therefore, the fragrance component located in the vicinity of the adherend in the holding layer is not diffused to the outside of the thin film, and the fragrance is hardly perceived after 6 hours from the application of the thin film. Further, in Comparative Example 1, many wrinkles were confirmed on the thin film on the skin, and the evaluation of transferability was poor. It is considered that this is because the thickness of the thin film is large and the adhesion between the thin film and the skin is low. Further, in Comparative Example 1, due to the high blockage rate, a feeling of strangeness such as stuffiness due to the sticking of the thin film was likely to occur, and the evaluation of the sticking feeling was also poor.
 また、単位面積当たりの質量が0.01g/m未満である比較例2では、その薄さに起因して閉塞率が5%よりも小さいことに加え、薄型フィルムに保持されている香料成分の総量も少ないために、薄型フィルムの貼付の6時間経過後には香気が知覚され難くなっている。さらに、比較例2では、薄型フィルムの強度が低いために、破れ等が生じて薄型フィルムの転写性の評価も悪くなっている。 Further, in Comparative Example 2 in which the mass per unit area is less than 0.01 g / m 2 , the blockage rate is smaller than 5% due to its thinness, and the fragrance component held in the thin film. Since the total amount of the thin film is small, it is difficult to perceive the fragrance after 6 hours from the application of the thin film. Further, in Comparative Example 2, since the strength of the thin film is low, tearing or the like occurs and the evaluation of the transferability of the thin film is also deteriorated.
 これに対し、単位面積当たりの質量が0.01g/m以上5.0g/m以下であり、閉塞率が5%以上60%以下である実施例1~4では、薄型フィルムの貼付の6時間経過後にも香気の知覚がサンプルの半数以上で可能であり、転写性および貼付感の評価もサンプルの半数以上で良好であった。したがって、実施例の薄型フィルムは、香料成分による効果の持続性が良好であるとともに、被着体に貼り付ける薄型フィルムとしての実用性も良好であることが示された。 On the other hand, in Examples 1 to 4 in which the mass per unit area is 0.01 g / m 2 or more and 5.0 g / m 2 or less and the blockage rate is 5% or more and 60% or less, the thin film is attached. Perception of aroma was possible in more than half of the samples even after 6 hours, and the evaluation of transferability and sticking feeling was also good in more than half of the samples. Therefore, it was shown that the thin film of the example has good sustainability of the effect of the fragrance component and also has good practicality as a thin film to be attached to the adherend.
 以上、実施形態および実施例にて説明したように、上記薄型フィルム、転写シート、および、転写シート収容体によれば、以下に列挙する効果を得ることができる。
 (1)薄型フィルム10の備える保持層が、機能成分として香料成分および抗菌成分の少なくとも一方を保持する。こうした構成によれば、保持層が香料成分を保持する場合、薄型フィルム10が芳香を放つ。また、保持層が抗菌成分を保持する場合、薄型フィルム10が貼り付けられた被着体において、細菌の繁殖が抑えられるため、細菌に起因した臭いの発生が抑えられる。したがって、においに関する機能の付与された薄型フィルムが実現され、薄型フィルム10において嗜好の多様化に対応することが可能となる。
As described above, according to the thin film, the transfer sheet, and the transfer sheet container, the effects listed below can be obtained as described in the embodiments and examples.
(1) The holding layer provided in the thin film 10 holds at least one of a fragrance component and an antibacterial component as a functional component. According to such a configuration, when the holding layer holds the fragrance component, the thin film 10 emits a fragrance. Further, when the retaining layer retains the antibacterial component, the growth of bacteria is suppressed in the adherend to which the thin film 10 is attached, so that the generation of odor caused by the bacteria is suppressed. Therefore, a thin film having a function related to odor is realized, and the thin film 10 can cope with diversification of tastes.
 また、保持層が機能成分を保持するため、機能成分が液状の媒体に含まれる場合と比較して、揮発等による機能成分の拡散が抑えられる。したがって、従来の芳香や消臭のための液状の製品と比較して、機能成分によるにおいに関する効果の持続期間を延ばすことができる。 Further, since the holding layer retains the functional component, diffusion of the functional component due to volatilization or the like is suppressed as compared with the case where the functional component is contained in the liquid medium. Therefore, the duration of the odor-related effect of the functional ingredient can be extended as compared with the conventional liquid products for fragrance and deodorization.
 (2)薄型フィルム10全体の質量に対する、保持層が保持する機能成分の質量の割合が、50ppm以上30%以下である。そのため、機能成分による効果が弱すぎることや過剰になることが抑えられ、機能成分による効果が良好に得られる。また、機能成分による効果の持続性も良好に得られる。 (2) The ratio of the mass of the functional component held by the holding layer to the mass of the entire thin film 10 is 50 ppm or more and 30% or less. Therefore, it is possible to prevent the effect of the functional component from being too weak or excessive, and the effect of the functional component can be obtained satisfactorily. In addition, the sustainability of the effect of the functional component can be obtained well.
 (3)薄型フィルム10の閉塞率が5%以上60%以下であることにより、薄型フィルム10の外部への機能成分の拡散が短時間に起こることや、機能成分の拡散性が極端に低くなることが抑えられ、機能成分の外部への拡散が好適な速度で進む。また、被着体が生体である場合に薄型フィルム10の貼付箇所に蒸れ等の不快感が生じることが抑えられる。 (3) When the blockage rate of the thin film 10 is 5% or more and 60% or less, the diffusion of the functional component to the outside of the thin film 10 occurs in a short time, and the diffusibility of the functional component becomes extremely low. This is suppressed, and the diffusion of the functional component to the outside proceeds at a suitable speed. Further, when the adherend is a living body, it is possible to suppress the occurrence of discomfort such as stuffiness at the place where the thin film 10 is attached.
 (4)薄型フィルムが拡散抑制層を備える形態であれば、機能成分の徐放性が高められる。また、保持層が2つの拡散抑制層に挟まれる形態であれば、機能成分の徐放性が高められるとともに、被着体が生体である場合に、機能成分が生体に与える刺激を抑えることができる。 (4) If the thin film has a diffusion suppressing layer, the sustained release property of the functional component is enhanced. Further, if the holding layer is sandwiched between two diffusion suppressing layers, the sustained release property of the functional component is enhanced, and when the adherend is a living body, the irritation given by the functional component to the living body can be suppressed. it can.
 (5)薄型フィルム10が、薄型フィルム10の表面に凹凸構造40を有する形態や、薄型フィルム10に、薄型フィルム10が備える層の少なくとも1つを貫通する貫通孔41が形成されている形態であれば、機能成分の外部への拡散が促進されるため、機能成分の徐放性の調整が可能である。また、保持層が、機能成分の包摂されたカプセル42を含有している形態や、薄型フィルムが拡散阻害物質を含有している形態であれば、機能成分の外部への拡散が抑えられるため、機能成分の徐放性の調整が可能である。 (5) The thin film 10 has an uneven structure 40 on the surface of the thin film 10, or the thin film 10 is formed with through holes 41 penetrating at least one of the layers included in the thin film 10. If there is, the diffusion of the functional component to the outside is promoted, so that the sustained release property of the functional component can be adjusted. Further, if the holding layer contains the capsule 42 containing the functional component or the thin film contains the diffusion inhibitor, the diffusion of the functional component to the outside can be suppressed. The sustained release of functional ingredients can be adjusted.
 (6)薄型フィルム10が、保持層や拡散抑制層に生体適合性材料を含む構成であれば、薄型フィルムが、生体への貼り付けに適した構成となる。特に、生体に対する安全性を高めるためには、第1面11Fを含む層が、生体適合性材料を含むことが好ましい。 (6) If the thin film 10 has a structure in which the holding layer and the diffusion suppressing layer contain a biocompatible material, the thin film has a structure suitable for sticking to a living body. In particular, in order to enhance safety to the living body, it is preferable that the layer containing the first surface 11F contains a biocompatible material.
 (7)転写シート50では、薄型フィルム10が支持基材51に支持されているため、薄型フィルム10の変形が抑えられるとともに、薄型フィルム10が取り扱いやすくなる。 (7) In the transfer sheet 50, since the thin film 10 is supported by the supporting base material 51, deformation of the thin film 10 is suppressed and the thin film 10 is easy to handle.
 (8)転写シート収容体60では、転写シート50が包装体61に収容されているため、転写シート50の使用前における機能成分の拡散が抑えられる。 (8) In the transfer sheet container 60, since the transfer sheet 50 is housed in the package 61, diffusion of functional components before use of the transfer sheet 50 is suppressed.
