Abstract: PURPOSE: A thermoplastic resin composition is provided to ensure excellent weather resistance and low gloss property and to avoid the deterioration of impact resistance and fluidity. CONSTITUTION: A low gloss thermoplastic resin composition includes (A) 30~80 weight% of an acrylic grafted copolymer resin in which the rubber particle diameter is 0.3~0.8 micron and (B) 20~70 weight% of an aromatic vinyl-cyanide vinyl copolymer resin. In the acrylic grafted copolymer resin, 40~70 weight% of the aromatic vinyl-cyanide vinyl copolymer is graft-polymerized with 30~60 weight% of acrylic rubbers. The vinyl cyanide monomer is selected from the group consisting of acrylonitrile, methacrylonitrile, ethacrylonitrile and a mixture thereof.
