VINYL CHLORIDE RESIN COMPOSITION FOR INJECTION MOLDING

The present invention provides a vinyl chloride resin composition for injection molding, including relative to 100 parts by mass of a vinyl chloride resin, (a) 0.01 to 10 parts by mass of an organic acid calcium salt and/or an organic acid zinc salt, (b) 0.01 to 10 parts by mass of a hydrotalcite compound, (c) 0.01 to 10 parts by mass of a beta-diketone compound, and (d) 0.01 to 10 parts by mass of a polyol mixture, wherein the polyol mixture of component (d) is a polyol mixture composed of pentaerithrytol and condensates thereof; when the degree of condensation of pentaerithritol is represented by n, the combined content of the pentaerithrytol and condensates thereof of n=1 to 3 is 5 to 40% by mass relative to the overall amount of the polyol mixture.
