Zusammenfassung:	PURPOSE:To obtain a marking compsn. sharply developing a color even when a color former containing a heavy metal is not used and capable of imparting a sharp mark especially by the irradiation with laser beam by adding a specific resin compsn. and color former particles in a specific ratio. CONSTITUTION:A marking compsn. is constituted of a specific resin compsn. and specific color former particles added to the resin compsn. in an amount of 1-100 pts.wt. The specific resin compsn. is formed from one or more kind of a thermoplastic resin, a thermosetting resin and a photo-setting resin. The specific color former particles are made colorless by coating the surfaces thereof with a wall film substance. The marking compsn. thus constituted develops a sharp color even when a color former containing a heavy metal is not used and can impart a sharp mark especially by the irradiation with laser beam.
