Abstract

The invention relates to a process for the coating of electrically conducting substrates in which PA0 (1) the substrate is immersed in an aqueous electrocoating paint comprising at least one cathodically depositable resin, PA0 (2) the substrate is connected as cathode, PA0 (3) a film is deposited on the substrate using direct current, PA0 (4) the substrate is removed from the electrocoating paint and PA0 (5) the deposited paint film is baked. In this invention an electrically conducting substrate coated by a coating produced by plasma polymerization is employed as substrate.
