挙げられる。Conventionally, as a method for forming an uneven pattern on the surface of a molded product, a method of molding using a mold having an uneven pattern on the inner surface is known, but the cost of the mold is high and
It is not easy to change the pattern, and in addition, injection molding has the disadvantage that fine lines, hairlines, fine uneven patterns, etc. are easily damaged by the injection pressure.For this reason, in recent years, it has become common to use a shaping film to form uneven patterns. has been adopted. Examples of methods for forming an uneven pattern using a forming film include a method in which a forming film is used as a base material of a transfer sheet to form an uneven pattern similar to that of the base material on the surface of a layer transferred from the transfer sheet; Examples of methods include pressing a shaping film onto the resin-coated surface and then peeling off the shaping film to form an uneven pattern on the resin-coated surface.

フィルム厚さが厚くなるという欠点があった。As a method for forming a concave-convex pattern on these shaping films, the concave-convex pattern is usually formed by an embossing method in which the concave-convex pattern is formed using a spacer and it is easy to synchronize the formed concave-convex pattern with a printed pattern, etc. be exposed. Traditionally, polypropylene, polyethylene, and
Films such as polyvinyl chloride and polyvinyl chloride/vinylon composite films are used, but these films have poor heat resistance, so the embossed shape may deform or disappear due to the heat during imprinting. There is a drawback that the film tends to curl, making it difficult to carry out printing operations when it is necessary to perform further printing on the film. Furthermore, such a shaping film with poor heat resistance is unsuitable for so-called in-mold molding, in which an uneven pattern is formed on the surface of an injection molded product by setting it in a mold and then injecting it. In order to improve the heat resistance of this type of shaping film, there is a method of combining it with a heat-resistant film, but this method has the drawbacks of high cost and increased film thickness.

った。In place of these films with poor heat resistance, shaping films made of heat-resistant polyester films such as polyethylene terephthalate are also used, but it is difficult to form uneven patterns on polyester films using the embossing method. The uneven pattern is formed by methods such as hairline and sandblasting, but forming the uneven pattern by these methods is more expensive than forming the uneven pattern by the embossing method, and it is difficult to synchronize with the printed pattern etc. like the embossing method. It is difficult to easily form such a concavo-convex pattern, and if an attempt is made to form a concavo-convex pattern that is in sync with a printed pattern, the process becomes complicated and costs increase.
