Abstract
The present invention relates to a thermoplastic resin composition, which includes a first copolymer formed by polymerizing a monomer mixture of a (meth)acrylate-based monomer, a vinyl cyan-based monomer and a maleimide-based monomer, and having a refractive index of 1.5170 or less and a glass transition temperature of 115.0° C. or more; and a second copolymer formed by graft-copolymerizing an aromatic vinyl-based monomer and a vinyl cyan-based monomer onto an acrylic rubber polymer, and the thermoplastic resin composition according to the present invention has improved heat resistance, colorability and scratch resistance.
