1. A thermoplastic resin composition, comprising:
100 parts by weight of a base resin comprising from 10 to 50% by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-1) containing a first acrylate rubber having an average particle diameter of from 0.3 to 0.5 μm, from 5 to 40% by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-2) containing a second acrylate rubber having an average particle diameter of 0.05 μm or more and less than 0.3 μm, and from 20 to 65% by weight of an aromatic vinyl polymer (B); and
from 0.5 to 12 parts by weight of a polyamide (C),
wherein the thermoplastic resin composition has a solvent resistance of 15 days or more, wherein the solvent resistance is measured as time when a crack occurs in a presence of a solvent consisting of 98% by weight of water, 1% by weight of citric acid, and 1% by weight of malic acid.
