Farvede, termoplastiske harpikssammensætninger til lasersvejsning, anthraquinonfarvestoffer dertil og stöbte produkter deraf

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.
