Description
本発明は、可視光透過率が高く、且つホログラムパターンの発現が要求されない印刷デザインに対して、その色調を変化させることなくホログラムパターンを確実に隠蔽し、しかも、ホログラムパターン層の形成前の印刷層及びホログラム隠蔽層が形成された基材フィルムを、ロールに巻き取る際の皺を防止することが可能なホログラムパターン付きフィルム及びそのフィルムを用いたホログラム容器に関する。 The present invention reliably conceals a hologram pattern without changing the color tone of a print design that has a high visible light transmittance and does not require the expression of a hologram pattern, and is also capable of printing before forming a hologram pattern layer. The present invention relates to a film with a hologram pattern capable of preventing wrinkles when a substrate film on which a layer and a hologram concealing layer are formed is wound on a roll, and a hologram container using the film.
近年、意匠性の向上を目的として、容器、包装物その他の対象物の外面にホログラムパターンを有するものが提案されている。このホログラムパターンは平面内に記録されたエンボス状又はレリーフ状をなす微細な凹凸形状とした溝であり、このホログラムパターンを備えたフィルムを別途作成し対象物の外面に貼着している。このホログラムパターンを備えたフィルムは基材層、印刷層、ホログラムパターン層、蒸着層、接着層が順次形成されている（例えば特許文献１）。印刷層は所定の印刷デザインに合わせて一部若しくは全面に形成されており、印刷が施されていない部分或いは、透明性のある印刷が施されている領域ではホログラムパターンが発現し、不透明な印刷を施した領域ではホログラムパターン層が隠蔽されホログラムパターンは消失する。 In recent years, for the purpose of improving the designability, those having a hologram pattern on the outer surface of a container, package or other object have been proposed. This hologram pattern is an embossed or relief-shaped groove recorded in a plane, and a film provided with this hologram pattern is separately prepared and attached to the outer surface of the object. A film provided with this hologram pattern has a base material layer, a printing layer, a hologram pattern layer, a vapor deposition layer, and an adhesive layer formed in order (for example, Patent Document 1). The print layer is partially or entirely formed according to a predetermined print design, and a hologram pattern appears in an unprinted part or an area where transparent printing is applied, and an opaque print The hologram pattern layer is concealed and the hologram pattern disappears in the region subjected to.
しかしながら、この構成では濃色系等の可視光透過率が低い印刷デザイン上では意匠性に何ら問題は発生しないが、白色や淡色系等の可視光透過率が高い印刷デザイン上においては、入射した光が印刷層を透過し蒸着層へ到達し反射することで、本来ホログラムパターンが要求されない領域にホログラムパターンが裏写り３２となって発現され意匠性が低下してしまう（図２ａ）。そこで、一般的には印刷層とホログラムパターン層の間に、遮光を目的に銀色等の可視光透過率が低いインキ層から成るホログラム隠蔽層を形成することが考えられるが、この場合、可視光透過率が低いインキの色調が印刷デザインの色調に影響を与え、印刷デザインの色調が暗くなってしまう。又、特に遮光を目的に一般的に用いられる銀色のインキでは含有されるアルミニウム粉末の影響で表面の摩擦抵抗が基材フィルムや他の領域の印刷層に比較し著しく大きくなり、このようなホログラムパターン層形成前の印刷層及びホログラム隠蔽層が形成されたフィルムは、ロールに巻き取る際にフィルムの幅方向のテンションが不均一となり、フィルムに皺が発生してしまう。 However, in this configuration, there is no problem in design on a print design with a low visible light transmittance such as a dark color system, but incident on a print design with a high visible light transmittance such as a white or light color system. When the light passes through the printing layer, reaches the vapor deposition layer, and is reflected, the hologram pattern appears as a show-through 32 in an area where the hologram pattern is not originally required, and the design is deteriorated (FIG. 2a). Therefore, in general, it is conceivable to form a hologram concealing layer composed of an ink layer having a low visible light transmittance such as silver for the purpose of light shielding, between the printed layer and the hologram pattern layer. The color tone of ink with low transmittance affects the color tone of the print design, and the color tone of the print design becomes dark. In addition, in the silver ink generally used for the purpose of light shielding, the surface frictional resistance is remarkably increased as compared with the base film and the printed layer in other areas due to the influence of the aluminum powder contained therein. When the film on which the printed layer and the hologram concealing layer are formed before the pattern layer is formed is wound on a roll, the tension in the width direction of the film becomes nonuniform, and the film is wrinkled.
これに対して、本願の発明者は、鋭意研究を行った結果、可視光透過率が高く、且つホログラムパターンの発現が要求されない印刷デザインに対して、印刷層とホログラム層との間に、下地インキ層、遮光インキ層、保護インキ層から成るホログラム隠蔽層を形成することにより、印刷デザインの色調を変化させることなくホログラムパターンを確実に隠蔽し、しかも、ホログラムパターン層の形成前の印刷層及びホログラム隠蔽層が形成されたフィルムを、ロールに巻き取る際の皺を防止することが可能であることを見出した。 On the other hand, the inventors of the present application have conducted intensive research, and as a result, for a print design that has high visible light transmittance and does not require the expression of a hologram pattern, By forming a hologram concealing layer composed of an ink layer, a light-shielding ink layer, and a protective ink layer, the hologram pattern is reliably concealed without changing the color tone of the print design, and the printed layer before the hologram pattern layer is formed and It has been found that wrinkles when a film on which a hologram concealing layer is formed are wound on a roll can be prevented.
そこで本発明は、印刷デザインの色調を変化させることなくホログラムパターンを確実に隠蔽して意匠性を高め、さらに、ホログラムパターン層の形成前の印刷層及びホログラム隠蔽層が形成されたフィルムを、ロールに巻き取る際の皺を防止することが可能なホログラムパターン付きフィルム及びそのフィルムを用いたホログラム容器を提供することを目的とする。 Therefore, the present invention improves the design by reliably concealing the hologram pattern without changing the color tone of the print design, and further, rolls a film on which the printed layer and the hologram concealing layer are formed before the hologram pattern layer is formed. An object of the present invention is to provide a film with a hologram pattern that can prevent wrinkles when wound on a film, and a hologram container using the film.
前記課題を解決するために、本発明のホログラムパターン付きフィルム及びホログラム容器は、基材フィルムに印刷層、ホログラムパターン層、蒸着層を順次形成したホログラムパターン付きフィルムにおいて、前記印刷層のうち、可視光透過率が高く、且つホログラムパターンの発現が要求されない印刷層の領域のみの上に、下地インキ層、遮光インキ層、保護インキ層から成るホログラム隠蔽層を形成し、保護インキ層の表面の摩擦抵抗が、ホログラム隠蔽層以外の領域における、基材フィルム及び印刷層の表面の摩擦抵抗と同じであることを特徴とする。 In order to solve the above-mentioned problems, a film with a hologram pattern and a hologram container according to the present invention are a film with a hologram pattern in which a printing layer, a hologram pattern layer, and a vapor deposition layer are sequentially formed on a substrate film. A hologram concealing layer consisting of a base ink layer, a light-shielding ink layer, and a protective ink layer is formed only on the printed layer area where the light transmittance is high and the hologram pattern is not required to be expressed, and the surface of the protective ink layer is rubbed. resistance, characterized in that in the region other than the hologram hidden蔽層is the same as the frictional resistance of the surface of the base film and a print layer.
本発明のホログラムパターン付きフィルムは、１，前記基材フィルムはポリエステルフィルムであること、２，前記下地インキ層のインキが白色インキであること、３，前記遮光インキ層のインキが銀色インキであること、４，前記保護インキ層のインキが白色インキであること、が好ましい。 The film with hologram pattern of the present invention is as follows: 1, the substrate film is a polyester film, 2, the ink of the base ink layer is a white ink, 3, the ink of the light shielding ink layer is a silver ink 4, the ink of the protective ink layer is preferably a white ink.
また、本発明のホログラム容器は、前記ホログラムパターン付きフィルムを用い、接着層を介して容器に接着することを特徴とし、前記容器が金属缶であることが好ましい。 Moreover, the hologram container of the present invention is characterized in that the film with a hologram pattern is adhered to the container through an adhesive layer, and the container is preferably a metal can.
本発明のホログラムパターン付きフィルムによれば、可視光透過率が高く、且つホログラムパターンの発現が要求されない印刷デザインに対して、その色調を変化させることなくホログラムパターンを確実に隠蔽し、さらに、ホログラムパターン層形成前の印刷層及びホログラム隠蔽層が形成されたフィルムを、ロールに巻き取る際の皺を防止することができる。 また、本発明のホログラム容器によれば、ホログラムパターンの発現が要求されない印刷デザインに対して、その色調を変化させることなくホログラムパターンが確実に隠蔽され、ホログラムパターンを有する意匠性が向上した印刷デザインに優れたホログラム容器とすることができる。 According to the film with a hologram pattern of the present invention, the hologram pattern is reliably concealed without changing its color tone with respect to a print design that has a high visible light transmittance and does not require the expression of the hologram pattern. It is possible to prevent wrinkles when the film on which the printed layer and the hologram concealing layer before forming the pattern layer are formed is wound around a roll. In addition, according to the hologram container of the present invention, the print design in which the hologram pattern is surely concealed without changing the color tone and the design property having the hologram pattern is improved with respect to the print design in which the expression of the hologram pattern is not required. It can be set as the hologram container excellent in.
以下、本発明の実施形態に係るホログラムパターン付きフィルム及びその製造方法について図面を参照しつつ説明する。図１に示すように、本発明のホログラムパターン付きフィルム１０は、基材フィルム１１、印刷層１２Ａ、１２Ｂ、ホログラムパターン層１６、蒸着層１８、接着層１９の順で形成されており、所定の印刷デザインにおいて可視光透過率が高く、且つホログラムパターンの発現が要求されない印刷デザイン（印刷層１２Ｂ）上に、下地インキ層１３、遮光インキ層１４、保護インキ層１５の順でインキを配置する構成を備える。 Hereinafter, a film with a hologram pattern and a manufacturing method thereof according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the hologram pattern-equipped film 10 of the present invention is formed in the order of a base film 11, printing layers 12A and 12B, a hologram pattern layer 16, a vapor deposition layer 18 and an adhesive layer 19, A configuration in which the ink is arranged in the order of the base ink layer 13, the light-shielding ink layer 14, and the protective ink layer 15 on the printing design (printing layer 12B) that has a high visible light transmittance and does not require the expression of the hologram pattern in the printing design. Is provided.
基材フィルム１１は透明性を有した材料で構成することが好ましく、例えばポリエチレンテレフタレートフィルム等のポリエステルフィルム、ナイロン（商標）製のフィルム、ＯＰＰ（延伸ポリプロピレン）フィルムその他の樹脂製フィルムを用いることができ、特にポリエステルフィルムが機械特性やハンドリングの点で好ましい。 The base film 11 is preferably composed of a material having transparency. For example, a polyester film such as a polyethylene terephthalate film, a nylon (trademark) film, an OPP (stretched polypropylene) film, or other resin film is used. In particular, a polyester film is preferable in terms of mechanical properties and handling.
この基材フィルム１１上に、所望の印刷デザインとなるように印刷層１２Ａ、１２Ｂを形成する。この印刷層１２Ａ、１２Ｂは、例えば、基材フィルム１１が巻き取られた原反を繰り出しながらグラビア印刷により印刷を施す。 Print layers 12A and 12B are formed on the base film 11 so as to have a desired print design. The print layers 12A and 12B are printed by gravure printing, for example, while feeding the original film on which the base film 11 is wound.
ここで、印刷デザインによっては、白色や淡色等のインキを施した可視光透過率が高い領域（印刷層１２Ｂ）が存在すると、前述したホログラムパターンの裏写り３２（図２ａ）が発現してしまう。そこで、この裏写り３２の発現を隠蔽するため、その印刷層１２Ｂの領域上に、例えばグラビア印刷によりホログラム隠蔽層を構成する下地インキ層１３を形成する。この下地インキ層１３に用いる下地インキは、印刷デザインを所望の色調にするものであれば良く、例えばグラビア印刷で一般的に用いる白色インキが好ましい。 Here, depending on the printing design, if there is a region (printing layer 12B) with high visible light transmittance to which ink of white or light color is applied, the show-through 32 (FIG. 2a) of the hologram pattern described above appears. . Therefore, in order to conceal the expression of the show-through 32, the base ink layer 13 constituting the hologram concealing layer is formed on the region of the print layer 12B by, for example, gravure printing. The base ink used for the base ink layer 13 is not particularly limited as long as the print design has a desired color tone. For example, white ink generally used in gravure printing is preferable.
また、この下地インキ層１３を形成した領域上に、遮光を目的に例えばグラビア印刷により、前記下地インキ層１３と同様にホログラム隠蔽層を構成する遮光インキ層１４を形成する。この遮光インキ層１４に用いる遮光インキは、前述したホログラムパターンの裏写り３２を発現させない可視光透過率の低いインキであれば良く、例えば、グラビア印刷で一般的に用いる銀色インキが好ましい。 Further, on the region where the base ink layer 13 is formed, a light-shielding ink layer 14 constituting a hologram concealing layer is formed in the same manner as the base ink layer 13 by, for example, gravure printing for the purpose of light shielding. The light-shielding ink used for the light-shielding ink layer 14 may be an ink with low visible light transmittance that does not cause the above-described hologram pattern show-through 32, and for example, silver ink generally used in gravure printing is preferable.
更に、遮光インキ層１４を形成した領域上に、例えば、グラビア印刷により、前記下地インキ層１３及び遮光インキ層１４と同様にホログラム隠蔽層を構成する保護インキ層１５を形成する。この保護インキ層１５に用いる保護インキは、他の領域の基材フィルム１１や印刷層１２Ａの表面の摩擦抵抗と同程度であればよく、例えばグラビア印刷で一般的に用いる白色インキが好ましい。そして、前記印刷層１２Ａ、１２Ｂ及びホログラム隠蔽層を構成する下地インキ層１３、遮光インキ層１４、及び保護インキ層１５は、ホログラムパターン層１６の形成前に基材フィルム１１に形成され、ロールに巻き取られるが、前記保護インキ層１５によって銀色インキ等から成る遮光インキ層１４を被覆するため、前記ロールに巻き取る際に皺を防止することができる。 Further, on the region where the light shielding ink layer 14 is formed, the protective ink layer 15 constituting the hologram concealing layer is formed by gravure printing, for example, similarly to the base ink layer 13 and the light shielding ink layer 14. The protective ink used for this protective ink layer 15 should just be comparable with the frictional resistance of the surface of the base film 11 of other area | regions or the printing layer 12A, for example, the white ink generally used by gravure printing is preferable. The base ink layer 13, the light-shielding ink layer 14, and the protective ink layer 15 constituting the print layers 12A and 12B and the hologram concealing layer are formed on the base film 11 before the hologram pattern layer 16 is formed. Although it is wound, the protective ink layer 15 covers the light-shielding ink layer 14 made of silver ink or the like, so that wrinkles can be prevented when winding on the roll.
次いで、ホログラムパターン層１６を形成するが、ホログラムパターン層１６は少なくとも硬化後に透明性を有する材料であればよく、例えば、熱可塑性樹脂、紫外線硬化型樹脂、自己硬化型材料を用いることができる。ホログラムパターン層１６は、印刷層１２Ａ、１２Ｂ及びホログラム隠蔽層を構成する下地インキ層１３、遮光インキ層１４、保護インキ層１５）の形成後に、一旦巻き取ったロールを繰り出しながら、例えば、塗布ロールによる転写、スプレーによる噴霧、スピンコートすることによって形成する。 Next, the hologram pattern layer 16 is formed. The hologram pattern layer 16 may be any material that is transparent at least after being cured. For example, a thermoplastic resin, an ultraviolet curable resin, or a self-curable material can be used. The hologram pattern layer 16 is formed by, for example, applying a roll while the rolled-up roll is unwound after the formation of the printing layers 12A and 12B and the underlying ink layer 13, the light-shielding ink layer 14, and the protective ink layer 15 constituting the hologram concealing layer. It is formed by transfer by spraying, spraying by spraying, spin coating.
そして、このホログラムパターン層１６上にホログラムパターン溝１７を形成するが、ホログラムパターン溝１７は、例えば、別途形成した母型の凹凸状のホログラムパターン溝を、ホログラムパターン層１６を構成する材料に押圧する等の公知の手段によって形成され、ホログラムパターン溝１７の形成後、ホログラムパターン層１６の材料に対応した手段で硬化させることによりホログラムパターン溝１７が定着する。 Then, a hologram pattern groove 17 is formed on the hologram pattern layer 16. The hologram pattern groove 17, for example, presses a separately formed mother-shaped uneven hologram pattern groove on the material constituting the hologram pattern layer 16. The hologram pattern groove 17 is fixed by curing by means corresponding to the material of the hologram pattern layer 16 after the hologram pattern groove 17 is formed.
ここで、母型の形成方法について説明する。例えば、フォトレジストを塗布した乾板にレーザー干渉膜を露光して、その干渉縞の濃度に応じた凹凸のレジストパターンを形成した後に、これに金属を蒸着して薄膜を形成して導電性を持たせ、その上にニッケルをメッキする。次に、このメッキ層を剥離することにより、ニッケル上に微細な凹凸状のホログラムパターンが精密に転写された母型が形成される。 Here, a method for forming a mother die will be described. For example, after exposing a laser interference film to a dry plate coated with a photoresist to form an uneven resist pattern corresponding to the density of the interference fringes, metal is deposited on this to form a thin film to have conductivity And nickel plating on it. Next, by peeling off the plating layer, a mother die in which a fine concavo-convex hologram pattern is precisely transferred onto nickel is formed.
最後に、ホログラムパターン溝１７上に、そのパターン溝に沿って蒸着層１８、例えば、スパッタリング、ＣＶＤ（ｃｈｅｍｉｃａｌ ｖａｐｏｒ ｄｅｐｏｓｉｔｉｏｎ）等により蒸着層１８を形成する。この蒸着に用いる材質は、高い光反射率を有すれば良く、例えばアルミニウムが好ましい。 Finally, the vapor deposition layer 18 is formed on the hologram pattern groove 17 along the pattern groove, for example, by sputtering, CVD (chemical vapor deposition) or the like. The material used for this vapor deposition should just have a high light reflectance, for example, aluminum is preferable.
以上の工程によりホログラムパターン付きフィルム１０が製造される。このように製造されたホログラムパターン付きフィルム１０において、ホログラム隠蔽層を構成する下地インキ層、遮光インキ層、保護インキ層の各層の有無によるホログラムパターン付きフィルムの参考例を表１に示す。 The film 10 with a hologram pattern is manufactured by the above process. Table 1 shows a reference example of a film with a hologram pattern according to the presence or absence of each of a base ink layer, a light-shielding ink layer, and a protective ink layer constituting the hologram concealing layer in the film 10 with a hologram pattern thus manufactured.
