Abstract

A coating composition for producing electrically conductive coatings, containing one or more electrically conductive pigments and an organic binder, as well as, optionally, additives and auxiliary agents, in an aqueous solvent, which organic binder contains a copolymer dispersible in water and based on (meth)acrylate- and silylated, unsaturated monomers. The total content of organic solvents in the composition does not exceed 0.5% by weight. The coatings thus obtained are especially well-bonded and resistant to mechanical influences and to solvents, and exhibit suitable conductivity (sheet resistivity) values.
