Abstract: A transparent thermoplastic resin composition includes (A) a rubber-modified vinyl-based copolymer; and (B) a cyanated vinyl-aromatic vinyl-based copolymer, wherein the (A) rubber-modified vinyl-based copolymer includes a rubbery polymer having an average particle size of about 500 Å to about 1,900 Å, the (B) cyanated vinyl-aromatic vinyl-based copolymer has a glass transition temperature of about 105° C. or less, and a difference in index of refraction between the (A) rubber-modified vinyl-based copolymer and the (B) cyanated vinyl-aromatic vinyl-based copolymer is about 0.01 or less. The transparent thermoplastic resin composition can have excellent properties in terms of scratch resistance, transparency, and/or impact resistance.
