PURPOSE:A composition that is obtained by adding a vinyl chloride resin with a specific porosity to another colored vinyl chloride resin with another specific porosity, thus forming partially colored moldings with high class appearance and low cost without postprocessing. CONSTITUTION:The objective composition is obtained by mixing (A) a colored vinyl chloride resin with a porosity (cc/100g of resin) of less than 10, preferably less than 5 with (B) another vinyl chloride resin with a porosity of more than 15, preferably more than 20 at a weight A/B ratio of 1/99-50/50. As component A, is preferred a combination of 2 or more differently colored PVC resins. Component A remains in the molding independently without gelling, while component B causes gelation to form the matrix of the moldings, thus giving partially colored moldings only by molding. |
