The present invention pertains to a thermoplastic resin composition containing a first copolymer and a second copolymer, wherein the first copolymer is formed by polymerizing a monomer mixture containing a (meth)acrylate-based monomer, a vinyl cyanide-based monomer, and a maleimide-based monomer, and has a refractive index of 1.5170 or less and a glass transition temperature of 115.0°C or higher, and the second copolymer is obtained by graft copolymerizing an aromatic vinyl-based monomer and a vinyl cyanide-based monomer with an acrylic rubber-like polymer. The thermoplastic resin composition according to the present invention has improved heat resistance, coloring properties, and scratch resistance. |
