When the paint film is heated to high temperatures after it is formed, there is no blistering from voids or pinholes in the paint film when the paint film is heated and dried, and a beautiful grain pattern of any size can be obtained. The object of the present invention is to provide a method for decorating plastic molded products.

A method for decorating a plastic molded product, which is characterized by forming a grained pattern.
＜実施の態様＞
以下、この発明の方法を、図例に基づいて詳細

A grain with a depth of ~50μ is formed using a mold during molding. At this time, if it is less than 20μ, the effect of hiding flow marks and degassing will not be sufficient, and if it exceeds 50μ, the paint cost will be high and it will be difficult to form the desired grain pattern by painting. Become. In addition, the materials include modified polyphelene oxide resin, polypropylene,
Examples include ABS, polycarbonate, polybutylene terephthalate, nylon 6, nylon 6,6, polystyrene, and polyethylene terephthalate.

That is, a highly blended paint is sprayed onto the surface to be coated in an incompletely atomized state using a spray gun to form a top coat film 3 (20 to 50 microns) having a wrinkled pattern on the desired surface. This top coat film 3 is left to stand for the required time (about 10 minutes) and then heated and dried (about 50° C. x 30 minutes).
