Abstract
A thermoplastic resin composition of the present invention is characterized by comprising: a base resin containing a rubber-modified vinyl-based graft copolymer, a large-diameter rubber polymer having an average particle size of about 3 to about 8 μm, and an aromatic vinyl-based copolymer resin; and polyorganosilsesquioxane fine particles having an average particle size of about 0.1 to about 10 μm. The thermoplastic resin composition is excellent in low gloss, weather resistance, and the like.
