RESIN COMPOSITION ON WHICH LASER-MARKING IS POSSIBLE, ITS MARKING AND MARKED MOLDED-ITEM

摘要

PROBLEM TO BE SOLVED: To obtain a resin composition which gives a molded item on the surface of which a marking having a clear and uniform contrast is applicable. SOLUTION: This composition is obtained by blending a component which is sensitive to laser beam such as carbon black, metallic compound white pigments or the like with a polyolefin resin and a dispersion assistant such as a higher fatty acid or the like. As the polyolefin resin, polypropylene or the like can be cited. In the resin composition, 0.5-30 pts.wt. of an elastomer can be added to 100 pts.wt. of the polyolefin resin.
