CA 2397977
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.
L'invention concerne des compositions de résines thermoplastiques renfermant des colorants complexe azo métallique 1:2 et convenant particulièrement au soudage par laser. Ces compositions comprennent une variété de résines thermoplastiques telles que des polyamides et des copolymères ainsi que des mélanges de celles-ci. Ces compositions présentent des propriétés de soudage supérieures et permettent d'obtenir le soudage d'articles de coloration identique au moyen de ces colorants.
