る。The resin molded product of Example 1 of the present invention exhibited excellent characteristics in all items of the color pattern, the three-dimensional appearance, and the partial matting. On the other hand, in the comparative example of the related art, at least one of the items was inferior. Looking at the details, with respect to the color pattern, Comparative Examples 4 and 5 are Examples 1 and 2.
As in the case of using a print film, a complicated pattern or the like can be industrially easily created by using a print film. However, in Comparative Example 3, it is possible to draw a picture, but it takes much time and is not industrially suitable. . In Comparative Example 2, a pattern like a marble pattern could be created by mixing the paints, but a fixed pattern could not be created. In Comparative Example 1, the color of the resin itself was used. Expression is impossible.

い。Next, as for the three-dimensional appearance, none of the comparative examples had a high degree of design such that the color pattern appeared three-dimensionally. Further, with respect to partial matting, partial matting can be formed in all resin molded articles by using a mold provided with irregularities, but is industrially satisfactory as compared with the present invention which does not depend on the mold. Not something.

を得ることができる。As described above, according to the present invention, the ultraviolet or thermosetting resin layer is buried in the thermoplastic film, and the surface of the thermoplastic film and the surface of the ultraviolet or thermosetting resin layer are substantially flat. As a result, it is possible to form a surface having excellent touch feeling, and partially between the region corresponding to the region where the ultraviolet or thermosetting resin layer of the print painting layer is provided and the other region. Since a step is formed on the surface, it is possible to obtain a three-dimensional appearance, a sense of depth, and a high design appearance.
