COLORED THERMOPLASTIC RESIN COMPOSITIONS FOR LASER WELDING, ANTHRAQUINONE COLORANTS THEREFOR AND MOLDED PRODUCT THEREFROM

摘要

Thermoplatic resin compositions suitable for laser welding are discribed in which black colorants are added. These colorants constitute amine salts of anthraquinone dyes. Additional dyes, coloring agents, and a variety of other materials may be added. These compositions demonstrate outstanding mechanical and chemical properties once laser-welded.
