PURPOSE: A thermoplastic resin composition is provided to enable the coating without a sanding process and to be suitable for two cavities blow molding, thereby enabling use for blow molding products. CONSTITUTION: A thermoplastic resin composition includes (a) 20~40 weight% of graft ABS copolymers, (b) 20~50 weight% of heat-resistant copolymer, (c) 20~50 weight% of aromatic vinyl compounds-vinyl cyanide compound copolymers, and (d) 0.01~0.1 weight% of salt compounds of magnesium metal. The graft ABS copolymer comprises 10~40 parts by weight of a first polybutadiene rubber latex with an average particle diameter of 800~1500 Å and a gel content of 80~90%, 15~40 parts by weight of a second polybutadiene rubber latex with an average particle diameter of 2500~3500Å and a gel content of 80~90%, 15~35 parts by weight of vinyl aromatic compounds, and 10~25 parts by weight of vinyl cyanide.
