PROBLEM TO BE SOLVED: To obtain a rigid resin composition having good moldability, heat resistance and deformation resistance by making the resin composition include talc in a rigid resin composition. SOLUTION: This composition is made to include a thermoplastic resin composition comprising (A) 90-10 wt.% chlorinated vinyl chloride-based resin composition containing 60-70 wt.% chlorine, (B) 0-80 wt.% vinyl chloride-based resin composition, and (C) 10-80 wt.% resin composition comprising (i) 30-100 wt.%α-methylstyrene-based copolymer ofα-methylstyrene, vinyl cyanide compound and another vinyl compound copolymerizable therewith and (ii) 0-70 wt.% graft copolymer obtained by copolymerizing 20-70 wt.% mixture including an aromatic vinyl compound, vinyl cyanide compound and another vinyl compound copolymerizable therewith in the presence of 30-80 pts.wt. rubber having a glass-transition temperature of <=0 deg.C, and (D) 1-20 pts.wt. talc having an average diameter of 0.8-12μm based on 100 pts.wt. of the above-mentioned thermoplastic resin composition. |
