摘要： A vinyl chloride resin composition with a yield stress of 1 to 5 g/mm.sup.2, composed of(A) 100 parts by weight of a vinyl chloride resin containing 0 to about 20% by weight of a comonomer,(B) about 10 to about 80 parts by weight, per 100 parts by weight of the resin (A), of (B-1) a liquid polyester plasticizer having a number average molecular weight (Mn) of not less than about 1,500 and 0 to about 10 parts by weight, per 100 parts by weight of the resin (A), of (B-2) a plasticizer for the resin (A), which is other than said plasticizer (B-1), and(C) about 0.2 to about 200% by weight, based on the total weight of said plasticizers (B-1) and (B-2), of a low-molecular-weight acrylic or methacrylic resin having a number average molecular weight (Mn) of about 1,500 to about 50,000 and being solid at 23.degree. C.
