LASER-WELDABLE WHICH ARE TRANSPARENTLY, TRANSLUCENTLY OR OPAQUELY DYED BY MEANS OF COLORANTS

摘要

The invention relates to plastic materials which are transparently, translucently or opaquely dyed by means of colorants and which can be laser-welded by means of nanoscaled laser-sensitive particles. The plastic materials, which are provided in the form of moulded bodies, semi-finished products or lacquer coatings, contain in particular laser-sensitive particles having a particle size of 5 - 100 nm and containing 0.0001 to 0.1 per cent by weight nanoscaled compounds such as indium tin oxide, antimony tin oxide, indium tin oxide and lanthanum hexaboride.
