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.
L'invention porte sur des compositions de résine thermoplastique convenant au soudage par laser et dans lesquelles des colorants noirs sont ajoutés. Ces colorants contiennent un sel aminé de colorants d'anthraquinone. Il est également possible d'ajouter dans lesdites compositions d'autres colorants, d'autres agents colorants, ainsi qu'une gamme d'autres substances.
