Abstract

A thermoplastic resin composition and a molded article including the same can include 100 parts by weight of a base resin including 10 to 50% by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-1) containing acrylate rubber having an average particle diameter of 0.3 to 0.5 μm, 5 to 40% by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-2) containing acrylate rubber having an average particle diameter of 0.05 μm or more and less than 0.3 μm, and 20 to 65% by weight of an aromatic vinyl polymer (B), and 0.5 to 12 parts by weight of a polyamide (C). The thermoplastic resin composition can have a solvent resistance of 15 days or more.
