DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative film used as a surface material for decoration by being attached to a window glass, a metal plate or the like, and a method for producing the same.

[0002]

2. Description of the Related Art For example, a decorative film adhered to a window glass, a metal plate, a plywood, or the like is formed of a transparent or translucent film or a colored film capable of transmitting light, a printed pattern such as wood grain, or an emboss. It has a textured pattern. Such a decorative film is disclosed in JP-A-3-29.
Japanese Patent No. 3130 discloses a decorative film in which a printed layer is formed on one side of the film, and a wiping layer is formed on the printed layer to bring about the texture of the film. ing.

[0003]

However, in the above-mentioned conventional decorative film, the one disclosed in Japanese Patent Application Laid-Open No. 3-293130 has a wiping layer which gives a texture to the printed layer. There is a disadvantage that the pattern by the layer is covered, and the effect of the pattern is impaired.

[0004] Further, since the ink filled by wiping or the like into the concave portion of the concavo-convex pattern formed by embossing is an ink containing a volatile solvent, it is contained in the ink inside the concave portion of the emboss. There is a drawback that the solvent that evaporates evaporates and becomes recessed in the recess. In this state, for example, if a transparent resin film is laminated on the uneven pattern side, air remains in the concave pattern formed by the embossing, and there is a problem that the decorative film has a poor appearance.

[0005] Further, as means for expressing the shine of trees, for example, there are a method in which a nonwoven fabric or a fibrous material is used as a base and a printing layer is provided thereon, or a method in which Japanese paper is laminated on the printing layer. However, there is a disadvantage that the adhesive strength is weakened because the adhesive is applied to each other.

In order to solve the above-mentioned problems, the present invention can sufficiently express the effect of a deep pattern by an uneven pattern or the effect of ink filled in a concave portion of the uneven pattern. An object of the present invention is to provide a decorative film and a method for manufacturing the same.

First Reference Example FIG. 1 is a sectional view of a decorative film 1 according to a first reference example. In the decorative film 1, first, a colored vinyl chloride resin film, which is a thermoplastic resin film, is used as a base film 2, and the surface 2a of the base film 2 is embossed to form an uneven pattern. Next, the concave portion 3 of the concavo-convex pattern is filled with an ink 5 using a thermoplastic resin as a binder by a wiping method.
Then, the base film 2 is heated to slightly restore the concave portions 3 of the concavo-convex pattern formed by the emboss, so that the surface of the convex portions 4 and the surface of the ink 5 in the concave portions 3 are formed smoothly, The decorative film 1 is as shown in FIG.

In the case of forming the concavo-convex pattern by the embossing described above, plastic deformation due to heat of the base film 2 causes
Processing is performed at a low temperature lower than the heating temperature at the time of normal embossing, so that it is easily restored a little by reheating. In addition, the depth of the concave portion 3 of the embossed pattern due to the emboss is at least twice the thickness of the ink formed by gravure printing,
That is, it is set to 10 μ or more and 100 μ or less. As a result, even if the ink 5 containing the thermoplastic resin as a binder is filled in the recess 3, and the ink 5 dries and becomes recessed in the recess 3, the recess 3 is reheated.
