Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminate which can be applied to a label or a packaging material having a feeling of being pressed when used for a book, a decorative box, or a packaging material comprising a molded container or a film.

[0002]

2. Description of the Related Art Conventional makeup methods for imparting metallic luster to a body to be decorated such as a book, a decorative box, or a molded container include:
So-called foil stamping was used. The foil stamping material (film) was formed by providing a release film with a peelable transparent colored layer, an aluminum vapor-deposited and thermally activated adhesive layer. Then, the foil-pressed film is pressed against the object to be decorated with a heated letterpress pattern, and a metallic pattern consisting of a transparent coloring layer and aluminum vapor deposition is thermally transferred from the release film to form an image. Then, when the transparent colored layer is yellow, a golden color can be formed, when the transparent colored layer is colorless, a silver color can be formed, and when the transparent colored layer is another color, an image can be formed in a metallic color.

[0003] A transparent colored layer is printed on a plastic film, and an aluminum foil is laminated on the printed surface, or a metal deposition is applied to express a metallic color.
Alternatively, a printed material having a metallic pattern layer formed on a body to be coated is printed by printing with an ink using a glitter pigment colored with a transparent pigment or dye as a coloring agent.

[0004] However, the method using foil stamping is as follows.
When providing another pattern layer on the body to be decorated, it is necessary to print on the body in a separate step. Foil stamping performed in a separate process is a low-efficiency intermittent process that requires a dedicated machine and jig (plate). In addition, in addition to the fact that the makeup object is deteriorated or deformed by the heat of the foil stamping process, the film of the foil stamping is badly cut, causing burrs, missing characters, and a metallic image cannot be formed sharply. there were.

[0005] In addition, a method of printing a plastic film with a transparent ink and laminating it on an aluminum foil or performing metal vapor deposition involves a method of forming a metallic pattern layer formed by vapor deposition or aluminum foil and another pattern layer. It can be formed continuously and accurately in the same process. However, due to the presence of the luster of the transparent plastic film interposed on the surface, a metallic image was not expressed on the surface, and a three-dimensional foil pressing feeling could not be provided.

When printing on the back surface of a plastic film by a method of printing with a glittering pigment colored with a transparent pigment or a dye as a coloring agent, the glossiness of the transparent plastic film interposed on the surface causes the presence of gloss. In addition, the metallic image was not expressed on the surface, and it was not possible to provide a three-dimensional foil pressing feeling. In addition, when printed on the surface of the base film, the metallic coloring property is poor and a sufficient feeling of foil pressing cannot be expressed, and the brilliant pigment easily falls off due to friction and the like because of poor affinity with the binder. There was a problem.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a conventional image having a metallic-colored foil-push feeling in the same printing step as another image. And
In a method in which a plastic film is printed with a transparent ink and laminated with an aluminum foil or a metal is vapor-deposited, an image having a foil pressing feeling that cannot be exhibited is continuously formed on the back surface of the base film of the laminate. It is another object of the present invention to provide a printed / laminated body in which the image appears to be provided on the surface of the laminated body.

Metallic glitter pigments include metal bimetallic fine powder, brass fine powder, and a plastic biaxially stretched film colored with a transparent colorant on a 4 to 15 μm thick polyester film on which 50 to 2000 nm of aluminum has been deposited. And pearl pigments such as fish scale foil using a transparent colorant. As the transparent colorant, any of a dye and a pigment can be used. From the viewpoint of transparency, the dye is a dye. However, a pigment that is chemically stable and has excellent light resistance and chemical resistance is preferable. For example, benzidine yellow, disazo yellow, chromophthal yellow, yellow pigments such as isoindoline yellow, chromophthal red, dioxazine violet, quinacridone red, red pigments such as perinone red, phthalocyanine blue, indathrone blue,
And phthalocyanine green. The preferred glitter pigment is a fragment of a vapor-deposited film having a vivid color and a metallic tone.

[0013] The binder used to make the glitter pigment into an ink is selected depending on the type of the base film. Generally, it is selected from nitrified cotton / polyamide, polyurethane, polyester, vinyl chloride / vinyl acetate copolymer, acrylic resin and the like. Further, an ink is prepared using a vehicle in which a binder to which additives such as a stabilizer are added is dissolved in a solvent. And the printing method is sheet-fed printing,
