Abstract: A thermoplastic resin composition includes a first copolymer including a conjugated diene-based polymer, a unit derived from an aromatic vinyl-based monomer, and a unit derived from a vinyl cyan-based monomer; a second copolymer including a unit derived from an aromatic vinyl-based monomer and a unit derived from a vinyl cyan-based monomer; and, with respect to 100 parts by weight of the sum of the first copolymer and the second copolymer, 2.0 to 10 parts by weight of a third copolymer having a soft segment including a unit derived from a polyalkylene glycol and a hard segment including unit derived from an aromatic dicarboxylic acid or aromatic dicarboxylate and a unit derived from a linear aliphatic diol; and 2.5 to 10 parts by weight of a fourth copolymer including an aromatic dicarboxylic acid-derived unit, a unit derived from a linear aliphatic diol, and a unit derived from a cyclic aliphatic diol.
