PURPOSE:A composition that is obtained by combining a colored PVC resin which has been crosslinked with an agent, with a usual PVC resin, thus giving partially colored moldings with high-class appearance in low costs without postprocessing. CONSTITUTION:The objective composition comprises (A) a vinyl chloride resin which has been crosslinked with an agent and colored and (B) a usual vinyl chloride resin at a weight A/B ratio of 1/99-50/50. As component A, is preferred a combination of 2 or more differently colored vinyl chloride resins. The crosslinking agent is preferably used by 0.1-10wt% based on the vinyl chloride monomer in component A, resulting in 1-80wt% gel fraction in tetrahydrofuran. Component A remains in isolated state in the matrics of component B, when the composition is molded, thus giving partially colored moldings by only molding. |
