PROBLEM TO BE SOLVED: To obtain a molded product having no color defficiency by final molding and to safely and inexpensively produce the molded product by a little washing load by integrally bonding a main material layer of a vinyl chloride resin compsn. containing no pigment and a coloring material layer of a vinyl chloride resin compsn. containing pigment. SOLUTION: The arranging shape of a main material layer and a coloring material layer may be set, for example, to a shape wherein the main material layer 1 and the coloring material layer 2 are laminated in a laminar state, a shape wherein a color layer 12 is further closely bonded to the surface of a columnar main material layer 11 or a shape wherein the coloring material layer is bonded to the semi- circumferential surface of a columnar main material layer 21 and, if the main material layer and the coloring material layer are uniformly bonded, there is no special limit. By forming pellets having a shape wherein the coloring material layer and the main material layer are closely bonded, the locallzation of a coloring material is prevented and, since the coloring material and the main material are closely bonded, the chewing dispersing effect of the coloring material is raised and a molded product having a developed color and color stability equal to those of a conventional molded product can be obtained by final molding. |
