Abstract
A vinyl chloride resin composition contains (a) a vinyl chloride resin and (x) a plasticizer. The (x) plasticizer includes (b) a trimellitic acid ester and (c) a polyester including a structural unit derived from adipic acid and a structural unit derived from 3-methyl-1,5-pentanediol. The total content of the (b) trimellitic acid ester and the (c) polyester is 65 parts by mass or more per 100 parts by mass of the (a) vinyl chloride resin, and the proportion constituted by the content of the (c) polyester in the total content of the (b) trimellitic acid ester and the (c) polyester is more than 50 mass %.
