Abstract

Provided is a thermoplastic resin composition that includes: a first copolymer including an unit derived from an aromatic vinyl-based monomer and an unit derived from a vinyl cyan-based monomer; a second copolymer including an unit derived from an alkyl (meth)acrylate-based monomer, an unit derived from an aromatic vinyl-based monomer, and an unit derived from a vinyl cyan-based monomer; a third copolymer including a conjugated diene-based polymer with an average particle diameter of 0.25 to 0.35 μm, an unit derived from an aromatic vinyl-based monomer, and an unit derived from a vinyl cyan-based monomer; and a fourth copolymer including a conjugated diene-based polymer with an average particle diameter of 0.05 to 0.15 μm, an unit derived from an aromatic vinyl-based monomer, and an unit derived from a vinyl cyan-based monomer, and can be used for producing a molded article exhibiting excellent basic properties while being capable of realizing selective transmittance.
