。Effect> According to this method of forming a multicolored skin material, the decorative material is interposed at the boundary between the color layers, and the decorative material and each color layer are bonded during heat molding, so the boundary is not formed as in the conventional method. Very clean boundaries can be obtained even without line grooves. Furthermore, since the decorative material serves as a boundary and joint, each color layer can be formed simultaneously, resulting in a short molding time. Furthermore, since the color layers do not overlap, no material is wasted. Furthermore, since the decorative materials can be attached at the same time, it saves time and effort.
