やシワが発生し、きれいな加飾成形品が得られない。However, in the former method, when the convex portion of the mold B has a large rise and the distance for pushing the decorative sheet into the cavity is long, the mold B is pushed when pushing the decorative sheet into the cavity. The corners of the convex portions of are strongly pressed against the decorative sheet. Therefore, the decorative sheet is damaged or wrinkled, and a beautiful decorative molded product cannot be obtained.
【０００５】また、後者の方法では、加飾シートの加熱

品４表面に転写するものである。The decorative sheet 2 is a sheet for decorating the surface of the molded product 4, and a transfer layer comprising a release layer, a decorative layer, an adhesive layer, etc. is formed on a long base sheet. It is a thing. The base sheet is a film-shaped material such as polyethylene terephthalate, polypropylene, or polybutylene terephthalate. The release layer is a resin layer that imparts releasability between the base sheet and the decorative layer. The decorative layer is a layer that imparts decorativeness and functionality to the surface of the molded product. The decorative layer has a pattern, a pattern made of printing ink such as characters and symbols, and a conductive pattern formed of a conductive material. You may have a metal vapor deposition layer if needed. The adhesive layer is a resin layer that adheres the decorative layer and the molded product 4 together. This decorative sheet 2 is a molded product 4
After adhering to the surface, the base sheet is peeled off, and only the transfer layer is transferred to the surface of the molded product 4.
