BLACK LASER WELDING POLYAMIDE RESIN COMPOSITION AND MOLDED ARTICLE USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a polyamide resin composition excellent in laser weldability and the like. PSOLUTION: The black laser welding polyamide resin composition comprises 100 pts.wt. polyamide resin (A), 0-100 pts.wt. reinforcing filler (B), and 0.01-1 pt.wt. colorant (C), and the above colorant (C) is a combination of at least one kind of a phthalocyanine pigment and at least one kind of a pigment and/or a dye other than the phthalocyanine pigment, and the optical transmission at a wavelength of 960 nm of a 1.5 mm-thick molded article composed of the resin composition is not less than 15%.
