Abstract:
Thermoplastic resin compositions suitable for laser welding are described in which black colorants are added. These colorants constitute amine salt 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.
