1. A vinyl chloride-based resin composition comprising a vinyl chloride-based resin, and a plasticizer composition comprising di(2-ethylhexyl)cyclohexane-1,4-dicarboxylate and di(2-ethylhexyl)adipate, and wherein a weight ratio of di(2-ethylhexyl)cyclohexane-1,4-dicarboxylate and di(2-ethylhexyl)adipate is 95:5 to 50:50 and wherein the resin has low temperature brittleness (LTB) is −41° C. or lower, as measured according to ASTM D746, haze is 9% or less, as measured according to ASTM D1003, and wherein the plastic migration is 0.48% or lower, as measured by placing oil-absorbing paper made of polypropylene on the top/bottom of a circular specimen with a thickness of 2 mm and a diameter of about 4 cm, and leaving at 60° C. for 7 days under a load of 5 kg to promote plasticizer migration, and then calculating the weight change rate of the specimen according to [(weight change of specimen/weight of specimen before test)*100].
