(57) [Abstract] [PROBLEMS] To develop a thermoplastic resin composition having excellent laser marking properties. SOLUTION: A glaze (at least two kinds of metal oxides), which is a glaze when baked, is added to 100 parts by weight of a thermoplastic resin. A resin composition comprising 01 to 10 parts by weight, and if necessary, 2 parts by weight or less of a pigment or a dye. This resin composition is excellent in laser marking properties, develops a bright black color, and is suitable for key tops and the like. |
