SYNTHETIC RESIN COMPOSINTION FOR PLASTIC ARTICLE HAVING METALIC SURFACE, INJECTION MOLDING METHOD AND PLASTIC ARTICLE USING THE SAME

摘要

PURPOSE: A synthetic resin composition for plastic articles is provided to ensure excellent appearance without weld line and flow mark and to solve problems on cost increase by additional coating of metallic pigment. CONSTITUTION: A synthetic resin composition for plastic articles includes 100 parts by weight of a thermoplastic resin, 0.1 - 10 parts by weight of plate shape metallic pigments(100), 1 - 50 parts by weight of spherical glassy materials(300), and 1 - 50 parts by weight of microfilament materials(200). An average particle size of the plate shape metallic pigment is 20 - 200μm.
