A resin composition for laser marking includes a resin and laser absorbers. The resin includes 40% 83% (methyl)acrylate-styrene based copolymers (A), 0 45% (methyl)acrylate based copolymers (B) and 5 35% core-shell copolymers (C) by weight. The laser absorbers include 0.01 0.25 parts of carbon black (D) for each 100 parts by weight of the resin. The (methyl)acrylate-styrene based copolymer (A) includes 40 80% (methyl)acrylate-containing monomer units, 20% to 60% styrene series monomer units and 0% to 30% other-polymerizable monomer units by weight. The (methyl)acrylate based copolymers (B) includes 92 99% methacrylate-type monomer units, 1 8% acrylate series monomer units and 0 7% vinyl-group-containing polymerizable monomer units by weight and has a weight-average molecular weight ranging from 70,000 to 150,000. Each core-shell copolymers (C) has a core portion that includes butadiene monomer units and (methyl)acrylate-containing monomer units and a shell portion that comprises (methyl)acrylate-containing monomer units at least partially covering the core portion.
