Abstract: PURPOSE: A thermoplastic resin composition is provided, which can be used to make a white-marking material with excellent definition and whiteness even at a low energy intensity of laser. CONSTITUTION: The thermoplastic resin composition comprises 100 parts by weight of an acryl-based resin; 0.01-5 parts by weight of a black dye or pigment; 0.01-10 parts by weight of a silicate-based compound; and optionally 20 parts by weight or less of a white inorganic filler. Preferably the acryl-based resin is a homopolymer or copolymer of at least one monomer selected from an acrylic acid or methacrylic acid, and alkyl acrylate or alkyl methacrylate, or a copolymer of an acryl-based monomer and at least one kind of vinyl ester-based monomer.
