Abstract
Provided is a thermoplastic resin composition which includes: a first graft copolymer including a first acrylic rubber polymer; a second graft copolymer including a second acrylic rubber polymer; and a first styrene-based copolymer including an alkyl-substituted styrene-based monomer unit and an acrylonitrile-based monomer unit, wherein the first acrylic rubber polymer has an average particle diameter larger than that of the second acrylic rubber polymer, the first graft copolymer is included in a larger amount than the second graft copolymer, and the sum of the first graft copolymer and the second graft copolymer is 22 parts by weight or less with respect to 100 parts by weight of the sum of the first graft copolymer, the second graft copolymer, and the first styrene-based copolymer.
