And at least one crosslink selected from the group consisting of a metal chelate compound, a metal oxide, and a metal hydroxide, which contains the component (B) comprising the copolymer, and the copolymer which is the component (A) is a metal chelate compound, a metal oxide, and a metal hydroxide Adhesives crosslinked by reaction with agents are disclosed. However, in both documents, the solubility of the drug is taken into consideration as well as the adhesiveness, and the moisture permeability in the case of using a waterproof film as a support is not considered.
- Patent Document 3 (A) adhesive polymer A containing a copolymer comprising methacrylic acid 2-acetoacetoxyethyl ester and other vinyl monomers as components and (B) an alkyl group having 4 carbon atoms Using a mixture of two kinds of pressure-sensitive adhesive of adhesive polymer B which comprises, as constituent components, ⁇ 10 (meth) acrylic acid alkyl esters and other vinyl monomers and which comprises a copolymer different from the above-mentioned adhesive polymer A Is disclosed.
- Patent Document 4 discloses a non-crosslinked medical adhesive comprising a pressure-sensitive adhesive polymer A having a weight-average molecular weight of 500,000 to 1,000,000, a pressure-sensitive adhesive polymer B having a weight-average molecular weight of 1,000,000 to 1.5 million, and a liquid plasticizer.
- Adhesive polymer A is a polymer obtained by copolymerizing N-vinyl-2-pyrrolidone with (meth) acrylic acid alkyl ester, and adhesive polymer B contains (meth) acrylic acid alkyl ester alone.
- a polymer obtained by polymerization or a polymer obtained by copolymerizing a (meth) acrylic acid alkyl ester with a comonomer other than N-vinyl-2-pyrrolidone as a medical non-crosslinked pressure-sensitive adhesive ing.
- a liquid plasticizer is used to improve the compatibility in the mixing of the pressure-sensitive adhesives, and further waterproofness, moisture permeability and adhesion are obtained. It does not consider sex.
- the subject of the present invention is that by using a mixed pressure-sensitive adhesive that mixes two types of acrylic pressure-sensitive adhesives, the skin becomes irritated or rashed even when a film material is used as a support for waterproofing. It is an object of the present invention to provide a patch which has both waterproofness, moisture permeability and adhesiveness.
- the present inventors have formulated, as an adhesive layer, specific two kinds of acrylic adhesives having good compatibility in a specific ratio and further crosslinking. Therefore, even when a film material was used as a support, it was thought that a patch having all of waterproofness, flexibility, and adhesiveness could be possible.
- Acrylic pressure-sensitive adhesives generally have (meth) acrylic acid alkyl ester as a main component as a monomer unit.
- the present inventors easily absorb sebum components secreted from the skin when the content of the (meth) acrylic acid alkyl ester having an alkyl group having 8 to 12 carbon atoms is a certain amount or more, and the patch Based on the finding that it is difficult to peel off, it was conceived to use (meth) acrylic acid alkyl ester having an alkyl group having 8 to 12 carbon atoms as the main component.
- acrylic pressure-sensitive adhesives in which the main component is a (meth) acrylic acid alkyl ester having an alkyl group having 8 to 12 carbon atoms are used as a mixed pressure-sensitive adhesive and are further crosslinked to obtain waterproofness and permeability required. It was conceived that it would be possible for a pressure-sensitive adhesive that is both wet and sticky.
- an acrylic pressure-sensitive adhesive which is a (meth) acrylic acid alkyl ester having an alkyl group having a carbon number of 8 to 12 as a main component is said to be hydrophilic because it is said to have hydrophobic properties.
- the present inventors are required to crosslink a vinyl monomer having a functional group, which is copolymerizable to (meth) acrylic acid alkyl ester to (meth) acrylic acid alkyl ester for crosslinking.
- a third component was sought which gives rise to the hydrophilic character.
- the compatibility between the two acrylic pressure-sensitive adhesives is appropriate in mixing.
- the use of a plasticizer is not preferable in order to reduce the properties of the adhesive.
- the inventors of the present invention may use a vinyl monomer having a hydrophilic property as a third component in earnestly seeking. I found it to be appropriate. That is, the present inventors have found a mixed pressure-sensitive adhesive of an acrylic pressure-sensitive adhesive having different characteristics of pressure-sensitive adhesive A (without third component) and pressure-sensitive adhesive B (with third component) depending on the presence or absence of the third component. It has been found that by crosslinking this mixed adhesive, an adhesive having both waterproofness and moisture permeability as well as adhesiveness is obtained.

1.支持体層
本発明の貼付材の支持体層は、フィルムや、織物、編物、不織布などの布帛等が挙げられるが、とりわけ、防水性を有するとともに、皮膚に密着することができ、かつ、皮膚の動きに追随することができる程度の柔軟な材質であって、そして長時間貼付後において皮膚のかぶれ等の発生を抑制できるフィルムを含むことが好ましい。
本発明の貼付材が備える支持体層は、厚みは、フィルムのみの場合は10~50μmの範囲であるが、フィルムと布帛からなる積層体の場合は20~250μmであってよく、好ましくは70~200μmである。フィルムと布帛からなる積層体の場合は、フィルムの厚さは、2~20μm、好ましくは3~10μmである。支持体層の厚みは、支持体層の厚みが薄すぎる場合には、支持体層の強度が不充分となり、貼付材を皮膚に貼り付けたり、貼付材を皮膚から剥がしたりする際に、支持体層が切れてしまうことがある。また、支持体層の厚みが大きすぎると、貼付材の厚みが大きくなる結果、貼付材が皮溝などの微細な凹凸のある皮膚表面に沿って密着しにくく、貼付状態が目立ちやすくなり、違和感も大きくなりやすい。
支持体層を形成するフィルムは、貼付中に、貼付材が目立たないようにする、すなわち、貼付下の皮膚の色調を透けて出しやすいという点では、透明性に優れたプラスチックフィルムが、好ましく採用されることが多いが、支持体層を形成するフィルムには、所望により、顔料や染料などの着色剤、安定剤、紫外線吸収剤、滑剤などの各種添加剤を含有させることができる。これら添加剤の含有量は、添加剤の種類によって最適な範囲を選定すればよいが、フィルムを構成する樹脂材料100質量部に対して、通常0.001~30質量部、好ましくは0.01~25質量部、より好ましくは0.1~20質量部の範囲とすることが多い。
貼付材をヒトの皮膚表面に貼り付けたとき、貼付材の手触り、滑り性、外観などを改善するために、貼付材を構成する支持体層の背面(支持体層の、粘着剤層側とは反対側に位置する面を意味する。)に、微小な凹凸を形成することが好ましい場合がある。すなわち、支持体層の粘着剤層側と反対側の面がエンボス加工されている貼付材とすることができる。エンボス加工により、支持体層表面の動摩擦係数を1.0未満に低減できる。なお、キャリア層の表面にエンボス加工によって微小な凹凸を形成しておき、該微小な凹凸面上に支持体層を形成すれば、エラストマーフィルムから形成される支持体層の表面(背面)に該微小な凹凸を転写することができる。
本発明の貼付材は、粘着剤層を形成する粘着剤が、以下の二つのアクリル系粘着剤を混合してなる混合粘着剤である。
必須成分として、炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステル65~99.5質量%、該(メタ)アクリル酸アルキルエステルと共重合可能な官能基を有するビニル単量体を0.5~8質量%、残りの成分として、さらに単量体合計100質量%となる範囲で、該(メタ)アクリル酸アルキルエステルや該ビニル単量体とは異なるビニル単量体であって、該(メタ)アクリル酸アルキルエステルと共重合可能な、親水性を有しないビニル単量体0~34.5質量%とからなる共重合体を含有するアクリル系粘着剤。
単量体合計100質量%となる範囲で、必須成分として、炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステル50~90質量%、該(メタ)アクリル酸アルキルエステルと共重合可能な官能基を有するビニル単量体を0.5~8質量%、該(メタ)アクリル酸アルキルエステルや該ビニル単量体とは異なるビニル単量体であって、該(メタ)アクリル酸アルキルエステルと共重合可能な、親水性を有するビニル単量体を9.5~49.5質量%とからなる共重合体を含有するアクリル系粘着剤。
粘着剤Aは、疎水性である。
本発明の貼付材で使用されるアクリル系粘着剤Aは、必須成分として、炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステルを65~99.5質量%、好ましくは75~99.3質量%、より好ましくは80~98質量%であり、該(メタ)アクリル酸アルキルエステルと共重合可能な官能基を有するビニル単量体を0.5~8質量%、好ましくは0.7~6質量%、より好ましくは、0.9~5質量%、残りの成分として、さらに単量体合計100質量%となる範囲で、該(メタ)アクリル酸アルキルエステルや該ビニル単量体とは異なるビニル単量体であって、該(メタ)アクリル酸アルキルエステルと共重合可能な、親水性を有しないビニル単量体0~34.5質量%、好ましくは0~24.3質量%、より好ましくは0~19.1質量%である。
粘着剤Aにおける必須成分である炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステルとしては、(メタ)アクリル酸n-オクチル、(メタ)アクリル酸2-エチルヘキシル、(メタ)アクリル酸イソオクチル、(メタ)アクリル酸イソノニル、(メタ)アクリル酸n-デシル、(メタ)アクリル酸イソデシル、(メタ)アクリル酸ラウリル等が挙げられる。これらの(メタ)アクリル酸アルキルエステルの中でも、アクリル酸2-エチルヘキシル、アクリル酸イソノニル等の炭素数8~9のアルキル基を有するアクリル酸アルキルエステルが、特に好ましい。これらの(メタ)アクリル酸アルキルエステルは、それぞれ単独で、または2種以上を組み合わせて用いることができる。
官能基は、粘着剤Aと粘着剤Bとを架橋するための官能基として働き、官能基としては、カルボキシ基、ヒドロキシ基、アミノ基、アミド基及びエポキシ基があり、中でもカルボキシ基及びヒドロキシ基が好ましい。カルボキシ基含有単量体としては、(メタ)アクリル酸、イタコン酸、マレイン酸が挙げられ、ヒドロキシ基含有単量体としては、(メタ)アクリル酸ヒドロキシルメチル、(メタ)アクリル酸ヒドロキシエチル、(メタ)アクリル酸ヒドロキシプロピルが挙げられ、また(メタ)アクリル酸ジエチレングリコールモノエステル等のポリアルキレングリコールの(メタ)アクリル酸モノエステルが挙げられる。アミノ基を有する単量体としては、(メタ)アクリル酸アミノエチル、アミド基含有単量体としては(メタ)アクリルアミドが挙げられ、エポキシ基含有単量体としては、グリシジルアクリレートが挙げられる。これらは2種類以上組み合わせて用いることもできる。好ましくは、アクリル酸、ポリエチレングリコールモノメタクリレートである。
このビニル単量体は、前記(1-1)、(1-2)のビニル単量体と異なる単量体であって、親水性を有しない。
粘着剤Bは、親水性である。
本発明の貼付材で使用されるアクリル系粘着剤Bは、単量体合計100質量%となる範囲で、必須成分として、炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステル50~90質量%、好ましくは51~88質量%、より好ましく52~86質量%、該(メタ)アクリル酸アルキルエステルと共重合可能な官能基を有するビニル単量体を、0.5~8質量%、好ましくは0.7~6質量%、より好ましくは、0.9~5質量%、該(メタ)アクリル酸アルキルエステルや該ビニル単量体とは異なるビニル単量体であって、該(メタ)アクリル酸アルキルエステルと共重合可能な、親水性を有する親水性を有するビニル単量体を9.5~49.5質量%、好ましくは11.3~48.3質量%、より好ましくは13.1~47.1質量%とからなる共重合体を含有する親水性を有するアクリル系粘着剤である。
親水性の特性を生じさせるために、第3成分として、親水性を有するビニル単量体を用いる。
本発明の貼付材の粘着剤層を形成する粘着剤A及び粘着剤Bを構成するアクリル共重合体は、ラジカル重合によって製造することができる。アクリル共重合体の重合法としては、溶液重合法、乳化重合法、塊状重合法などが知られているが、本発明の貼付材が備える粘着剤層が、良好な粘着特性を得やすい点で、溶液重合法が好ましい。アクリル共重合体を得るための重合開始剤としては、ベンゾイルパーオキサイド、ラウロイルパーオキサイド等の有機過酸化物;アゾビスイソブチロニトリル等のアゾ系開始剤;などが挙げられる。具体的には、アクリル共重合体を形成する前記のb-1)、b-2)及びb-3)からなる全単量体100質量部に対して、0.1~3質量部のラジカル重合開始剤を加え、窒素気流下、40~90℃程度の温度で、30分間~30時間撹拌して共重合させる。溶液重合法では、溶媒として、酢酸エチル、アセトン、トルエン、またはこれらの混合物などが汎用される。
本発明の粘着剤層は、粘着剤Aと粘着剤Bが、粘着剤Aと粘着剤Bとの合計質量を100質量部としたとき、15/85~85/15(質量比)の割合で混合され、さらに架橋した構造を有している。粘着剤Aは疎水性を有し、また粘着剤Bは親水性を有するものであるが、混合粘着剤が粘着剤層として一体化したものとするため、お互いに相溶性を有することが大切であり、本発明においては、両者の主要構成成分である炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステルが同一のものであるか、同一でない場合であっても、溶解度パラメータのSP値の差が0.50以内のものが好ましく使用される。粘着剤Aと粘着剤Bの好ましい混合比は25/75~75/25%(質量比)であり、35/65~65/35(質量比)がさらに好ましい。
本発明において、粘着剤Aと粘着剤Bが混合処理によって、架橋剤なしで架橋するものでもよいが、架橋剤によって架橋されることも好ましく、架橋剤としては、多官能イソシアネート化合物〔トリレンジイソシアネート(TDI)、4,4´-ジフェニルメタンジイソシアネート(MDI)、ヘキサメチレンジイソシアネート、キシリレンジイソシアネート、メタキシリレンジイソシアネート、1,5-ナフタレンジイソシアネート、水素化ジフェニルメタンジイソシアネート、水素化トリレンジイソシアネート、水素化キシリレンジイソシアネート、イソホロンジイソシアネート等〕や多官能エポキシ化合物、アセチルアセトン金属塩などが挙げられ、市販品として、例えば、日本ポリウレタン工業株式会社製のコロネート(登録商標)HL、コロネートL、コロネートEH、三菱ガス化学株式会社製のTETRAD-X、(登録商標)、TETRAD-C(登録商標)、ナーセム(登録商標)アルミニウムなどとして入手することができる。架橋剤の含有量は、粘着剤Aと粘着剤Bにおけるアクリル共重合体の合計量100質量部に対して、好ましくは0.01~1質量部、より好ましくは0.03~0.5質量部、特に好ましくは0.04~0.1質量部である。架橋剤は、単独で、または2種類以上を用いてもよく、同時に2種類以上の添加を行わなくてもよく、粘着剤層を形成するための粘着剤の塗工前または塗工中に添加する方法などが挙げられる。
本発明の粘着剤層には、前記の粘着剤A及び粘着剤Bと架橋剤のほかに、必要に応じて、各種添加剤を含有することができる。添加剤としては、薬物、充填剤、酸化防止剤(抗酸化剤、防腐剤)、着色剤、香料、粘着付与剤、可塑剤など、貼付材が備える粘着剤層を形成する粘着剤において慣用されている添加剤を含有することができる。例えば、粘着剤の粘着特性を調整するために、粘着付与剤を配合することができる。粘着付与剤としては、例えば、テルペン系、テルペンフェノール系、クマロンインデン系、スチレン系、ロジン系、キシレン系、フェノール系、石油系などの粘着付与樹脂を挙げることができる。
本発明における粘着剤層を形成する粘着剤A及び粘着剤Bは、相溶性を有するものを使用し、さらに架橋処理が行われるため、通常、貼付材における粘着剤に含有されている可塑剤を含有する必要がない。かかる可塑剤としては、例えば、多価アルコール類(グリセリン、ソルビトール、プロピレングリコール、1,3-ブチレングリコール、1,3-テトラメチレングリコール、ポリエチレングリコール等);フェノール類(チモール、サフロール、イソサフロール、オイゲノール、イソオイゲノール等);高級アルコール類(ベンジルアルコール、オレイルアルコール、セチルアルコール、ステアリルアルコール、セトステアリルアルコール、オクチルドデカノール等);エステル系界面活性剤(セスキオレイン酸ソルビタン、ポリオキシエチレン硬化ヒマシ油、ステアリン酸ポリオキシル等);脂肪酸エステル類(ミリスチン酸イソプロピル、ミリスチン酸オクチルドデシル、オレイン酸オレイル、フタル酸ジエチル、フタル酸ジブチル等);有機酸類(乳酸、クエン酸、酒石酸、マレイン酸、リンゴ酸等);など室温で液体状である可塑剤が知られている。
本発明における粘着剤層には、通常貼付材における粘着剤に含有される各種の薬物を含有することができる。かかる薬物としては、ジカプリル酸ピリドキシン、グリチルリチン酸ジカリウム、ジパルミチン酸ピリドキシン、グリチルリチン酸、塩酸ジフェンヒドラミン、オウバクエキス、ステアリン酸グリチルレチニル、塩化リゾチーム、アミノカプロン酸、レイシエキス、ヨクイニン、メリロートエキス、ボタンエキス、トウキエキス、トウキ根エキス、センキュウエキス、ゲンノショコエキス、アラントイン、及びアルニカエキス等の抗炎症剤;シコニン、ヒノキチオール、セドロール、塩化ベンザルコニウム、塩化ベンゼトニウム、感光素201号、及びアジピン酸等の抗菌剤;エストラジオール、ビタミンB2、ビタミンB6、ローヤルゼリーエキス、リボフラビン等の皮脂分泌抑制剤;多孔質ナイロンパウダー及び多孔質セルロースパウダー等の吸油性多孔質粉体;カオリン、タルク、粘土、酸化亜鉛等の皮脂吸収剤;サリチル酸、イオウ、ベントナイト、シクロデキストリン等の角質剥離剤;ジブチルヒドロキシトルエン、酢酸トコフェロール、アスコルビン酸、安息香酸類、パラベン類、塩化ベンザルコニウム、及び塩化ベンゼトニウム等の抗酸化剤(防腐剤);アルニカモンタナエキス、甘草エキス、レチノール、グリチルリチン酸ジカリウム、シャクヤクエキス、セージ葉エキス、ビワ葉エキス、ローズマリーエキス等の肌荒れ改善剤;ビタミン及びブチルヒドロキシトルエン等の酸化防止剤;さらに、各種の鎮痛消炎剤;抗ヒスタミン剤;コルチコステロイド剤;保湿剤;ビタミン類;香料;美容成分;などが挙げられる。
本発明の貼付材における粘着剤層の厚みは、10~200μmの範囲であり、好ましくは15~150μm、より好ましくは20~100μmの範囲である。
本発明の貼付材は、支持体層、粘着剤層の他に、通常、救急絆創膏と使用する場合には、粘着剤層を皮膚に貼り付けるときまで、粘着剤層を保護するために、粘着剤層に隣接してセパレーター層が備えられる。
通常、支持体層が薄い場合、貼付材は、キャリア層、支持体層、粘着剤層及びセパレーター層を、この順に積層して備える貼付材とすることが好ましい。貼付材は、支持体層に麟接してキャリア層を備えることにより、貼付材の取扱い性、皮膚への貼付性を向上させることができ、また、貼付材の製造方法において、支持体層の形成を容易にすることができる。すなわち、貼付材を皮膚に貼り付ける際、支持体層にシワが入ったり、貼付材が折れ曲がって粘着剤層同士が接着してしまったりすることがあるが、貼付材が支持体層に隣接してキャリア層を備えることにより、貼付材の形状保持性が向上するので、こうした問題を防止することができる。キャリア層の厚みは、適宜設定することができ、特に限定されないが、通常20μm以上、好ましくは40μmであり、その上限値は500μm程度である。
本発明の貼付材は、防水性を付与するための支持体と粘着剤層を備えるものであり、貼付材としての高い透湿性と高い粘着力を有するものである。透湿度としては300g/m2・24h以上を有することが好ましく、また、プローブタックが1.0~4.0N/5mmφであることが好ましい。
本発明の貼付材は、支持体層、粘着剤層を備える貼付材であって、更に、前記した諸特性を備えるものである限り、特に形状が限定されず、救急絆創膏や粘着テープあるいは経皮吸収製剤としての特性にあわせた形状とすることができ、例えば粘着テープとする場合は、ロール状とすることができ、救急絆創膏や経皮吸収製剤であれば、円形、長円形や使用目的に応じた形とすることが可能である。
本発明の貼付材は、透湿度として300g/m2・24h以上、好ましくは600g/m2・24h以上、より好ましくは650g/m2・24h以上、さらに好ましくは700g/m2・24h以上、特に好ましくは750g/m2・24h以上である。上限は、1500g/m2・24h、好ましくは1,070g/m2・24hである。透湿度が大きいことによって、貼付材を皮膚に貼り付ける際に、蒸れたり、汗が溜まったりするのを防ぐことができる。透湿度は、JIS Z0208に規定されるB条件(温度40℃、相対湿度90%)で測定する。
本発明の貼付材は、プローブタックが1.0~4.0N/5mmφであることが、好ましく、1.95~3.70N/5mmφであることがより好ましく、1.96~3.60N/5mmφであることが更に好ましく、1.97~3.57N/5mφであることが特に好ましい。プローブタックが小さすぎると、貼付中に貼付材が脱落してしまう場合もある。また、プローブタックが大きすぎると、貼付材を貼付後に皮膚表面から剥離するときに抵抗感や痛みを感じる場合がある。
本発明の貼付材は、支持体層及び粘着剤層を備える貼付材であって、該粘着剤層が、
(a)粘着剤A:必須成分として、炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステル65~99.5質量%であり、該(メタ)アクリル酸アルキルエステルと共重合可能な官能基を有する単量体が0.5~8質量%で、残りの成分として、さらに単量体合計100質量%となる範囲で、該(メタ)アクリル酸アルキルエステルや該ビニル単量体とは異なるビニル単量体であって、該(メタ)アクリル酸アルキルエステルと共重合可能な、アルコキシ基を有しないビニル単量体0~34.5質量%とからなる共重合体を含有するアクリル系粘着剤、及び
(b)粘着剤B:単量体合計100質量%となる範囲で、必須成分として、炭素数8~12のアルキル基を有する(メタ)アクリル酸アルキルエステルが50~90質量%で、該(メタ)アクリル酸アルキルエステルと共重合可能な官能基を有する単量体が0.5~8質量、該(メタ)アクリル酸アルキルエステルや該ビニル単量体とは異なるビニル単量体であって、該(メタ)アクリル酸アルキルエステルと共重合可能な、アルコキシ基を有するビニル単量体9.5~49.5質量%からなる共重合体を含有するアクリル系粘着剤
とを混合してなる混合粘着剤であり、かつ、(i)該粘着剤Aと該粘着剤Bの混合比が、粘着剤Aと粘着剤Bとの合計質量を100質量部としたとき、15/85~85/15(質量比)であり、かつ、(ii)該混合粘着剤が架橋されていることを特徴とする貼付材を得ることができる限り、その製造方法は限定されない。本発明の貼付材は、シート状の積層体として製造することができるし、ロール状の積層体として製造することもできる。通常の貼付剤の製造方法を採用することができ、一般的な貼付剤の製造方法であるホットメルト法や、カレンダー法や溶展法などを採用することができ、中でも溶展法が好ましい。溶展法とは、必要な成分を溶剤に溶解して支持体に展開し、その後溶剤を蒸散して支持体と貼り合わせ、次いで適当な形状に裁断して貼付剤を得る方法である。
本発明の貼付材は、必要に応じて、キャリア層、セパレーター層をつけ、使用部位に応じた形状にして、一般的な救急絆創膏として使用できる。また、そのまま医療用粘着テープとして使用できるし、特定の薬剤を加えた経皮吸収製剤とすることも可能である。
支持体層、粘着剤層及び貼付材の厚みは、ダイヤルシックネスゲージを用いて測定した(単位:μm、n=3の平均値)。
貼付材の透湿度は、JIS Z0208に規定されるB条件(温度40℃、相対湿度90%)で測定した(単位:g/m2・24h、n=3の平均値)。
粘着剤層のプローブタックは、ニチバン株式会社製プローブタックテスターを使用して、JIS Z0237(1996年版)に参考として記載されているプローブタック試験法に従い、直径5mmの円柱プローブを粘着面から垂直方向に引きはがすのに要する力を測定して求めた(単位:N/5mmφ、n=3の平均値)。
貼付材の実用評価として、成人男女5名の被験者の入浴後の水分をふき取った後、指の第二関節に貼付剤を貼付し、12時間貼付した後、入浴し『入浴後の付着性』評価した。その後、貼付から24時間後に『24時間貼付後の付着性』を評価したのち、貼付材を剥離し、『皮膚のふやけ』を評価した。評価は、被験者5名それぞれ下記基準に沿って1~5で評価し、その平均値を四捨五入し、下記の基準により評価した。また、総合評価は、特性評価と実用評価の結果を踏まえて、本発明者らが評価した。

動的粘弾性測定のtanδ(損失正接)の温度依存から、そのピークによりガラス転移温度(Tg)が得られ、粘着剤A1のガラス転移温度は-33.2℃、粘着剤B1のガラス転移温度-19.4℃に対し、混合粘着剤C1のガラス転移温度は、-29.3~-27.6℃の範囲で1つのピークのみが確認された。したがって、混合粘着剤C1のガラス転移温度は、粘着剤A1と、粘着剤B1のそれぞれのガラス転移温度の中間点の-26.3℃に近い値となり、相溶性が認められた。
ポリウレタンフィルムにポリウレタン不織布を積層した支持体の上に、通常の製法により、混合粘着剤C1による粘着剤層を設けた貼付材(支持体層の厚さ170μm、粘着剤層の厚さ40μm)を得た。粘着剤A1及び粘着剤B1の混合比を変えて、同様の方法で貼付材として、粘着剤A1と粘着剤B1の混合比による影響を調べた。それぞれの貼付材の実用評価と特性評価を行った。結果を表1に示す。
ポリウレタンエラストマーフィルム(厚さ30μm)に混合粘着剤C1による粘着剤層(厚さ40μm)を設けた貼付材を得た。粘着剤A1を50質量部、粘着剤B1を50質量部の混合比で、実用評価と特性評価を行った。結果を表1に示す。
表1から、支持体がフィルム/不織布の実施例1~7の場合、粘着剤Aは単独では透湿度が594g/m2・24hと低いが、透湿性のよい粘着剤Bを混合粘着剤100質量部中で15質量部以上配合した場合に、透湿度650g/m2・24hを超えるものとなることが分かった。上記の粘着剤Aと粘着剤Bとの混合比が35/65~65/35(質量比)のときに最もよい実用評価が得られた。
