    Abstract: The present invention relates to high-transparency plastic materials which are laser-markable and/or laser-weldable due to a content of nanoscale laser-sensitive metal oxides. These plastic materials, which may be provided as molded bodies, semifinished products, molding compounds, or lacquers, particularly contain metal oxides having particle sizes from 5 to 100 nm and a content of 0.0001 to 0.1 weight-percent. Typical metal oxides are nanoscale indium-tin oxide or antimony-tin oxide. These materials may be used in particular for producing laser-markable production products.

    Abstract: The present invention relates to transparent, translucent, or opaque plastic materials that are tinted due to colorants, which are laser-weldable due to a content of nanoscale laser-sensitive particles. These plastic materials, which may be provided as molded bodies, semifinished products, or lacquer coatings, particularly contain laser-sensitive particles with a particle size from 5 to 100 nm and a content from 0.0001 to 0.1 weight had percent. Typical compounds are nanoscale indium-tin oxide, antimony-tin oxide, indium-zinc oxide, and lanthanum hexaboride.
