Abstract: PURPOSE: A thermoplastic resin composition is provided to exclude a painting process, and to have excellent appearance. CONSTITUTION: A thermoplastic resin composition comprises a rubber-modified aromatic vinyl-based graft copolymer; a non-graft copolymer copolymerized of 75-90 wt% of an aromatic vinyl-based monomer and 10-25 wt% of an unsaturated nitrile monomer; and a modified aromatic vinyl-based non-graft copolymer polymerized of an acrylic monomer, an aromatic vinyl-based monomer, and an unsaturated nitrile-based monomer. The weight average molecular weight of the aromatic vinyl-based non-graft copolymer is 100,000-180,000 g/mol.
