Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition for laser marking, having excellent color development of laser marking, improved practical impact resistance and chemical resistance. SOLUTION: This composition features compounding (A) 100 pts.wt. of a thermoplastic resin component composed of 50-100 wt.% of a rubber reinforced resin (A-1) subjected to graft polymerization with a small amount of a (meth) acrylic ester and 50-0 wt.% of a copolymer (A-2) copolymerized with a specific amount of a vinyl cyanide compound as main components and containing a specific amount of a polymerized vinyl cyanide compound with (B) 0.01-5 pts.wt. of a black-based compound such as carbon black.
