摘要： Novel halogen-free flame-retardant thermoplastic molding compositions are described, and give laser-markable moldings with increased quality of marking. The molding compositions comprise at least one thermoplastic A) and at least one light-sensitive compound of salt type B1) which within the polymer matrix when exposed to laser light changes its color or leads to a change in the color of the polymer matrix, and/or at least one light-sensitive or light-sensitizing oxide B2) which within the polymer matrix when exposed to laser light changes its color or leads to a change in the color of the polymer matrix, and at least one halogen-free compound or mixture C) which has a positive effect on the flammability and fire performance of the molding composition, and if appropriate, other conventional additives D).The invention further relates to moldings produced from these laser-markable flame-retardant molding compositions, and also to laser-marked moldings produced therefrom. A process for laser marking is also disclosed, as is the use of the laser-markable, flame-retardant molding compositions for production of laser-marked moldings.
