THERMOPLASTIC RESIN COMPOSITIONS FOR LASER WELDING AND ARTICLES FORMED THEREFROM

摘要

Thermoplastic resin compositions are disclosed that incorporate 1:2 metallic azo complex dyes and are particularly suitable for laser welding. These compositions include a variety of thermoplastic resins such as polyamides and copolymers and blends thereof. The compositions offer superior welding properties and provide for the welding of articles identically colored with these dyes.
