Una composición de resina termoplástica para la soldadura por láser que comprende: 1) una resina termoplástica; y 2) un colorante negro transmisor de láser que transmite luz láser en el infrarojo cercano desde 800-1200 nm que contiene sales de amina de pigmento de antraquinona que muestran colores azul, violeta o verde y pigmento de complejo de monoazo, que es un pigmento de color negro. Thermoplastic resin compositions are described in which amine salts of anthraquinone dyes and monoazo complex dyes are added. These compositions show superior performance in laser welding applications.
