Abstract
The present invention relates to an LDS-active additive for LDS plastics, to a polymer composition comprising an additive of this type, and to an article having metallized conductor tracks in which a polymeric basic body of the article or a polymeric coating on a basic body comprises an LDS additive of the said type.
Claims20
A method of preparing a polymeric composition for use in laser direct structuring, said method comprising adding to the polymeric composition a pigment which comprises doped tin dioxide as a laser direct structuring additive, wherein the doping consists of one or more non-metallic elements.
A polymeric composition comprising at least one organic polymeric plastic and a laser direct structuring additive, where the laser direct structuring additive comprises pigments which comprise doped tin dioxide, where the doping consists of one or more non-metallic elements.
An article having a circuit structure produced in a laser direct structuring process, consisting of a plastic basic body or a basic body having a plastic-containing coating and metallic conductor tracks located on the surface of the basic body or coating, where the plastic basic body or the plastic-containing coating of the basic body comprises a laser direct structuring additive which comprises pigments which comprise doped tin dioxide, where the doping consists of one or more non-metallic elements.
