Claim 11:
12. A thermoplastic resin composition, comprising:
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,
wherein the monomer mixture does not comprise an aromatic vinyl-based monomer.
