Abstract

A process for the production of electrically conductive layers on the surface of plastics in which the surface of a plastic filled with electrically conductive constituents is irradiated with laser energy in such a way that the plastic is evaporated down to a predetermined depth at the point of incidence by the laser energy, leaving behind the electrically conductive constituents, which increase in concentration and thus form an electrically conductive layer. With the aid of the process, plastic moldings with integrated electrically conductive layers or tracks on the surface can be produced, for example components used in the electrical and electronics industries or other large or small plastic parts of any desired shape which are provided with conductive elements in certain places. The molding can also be a constituent of a composite article with other materials.
