Abstract

The invention relates to a process for the electrostatic lacquering of non-conductive surfaces. For this purpose, a layer of a conductive organic polymer from the class of the polypyrroles, polyanilines or polythiophenes is applied to the surface and this layer is then electrostatically lacquered.
