Abstract

The invention relates to a method for autophoretically coating a metal substrate at a pH value of 1 to 4 and a substrate immersion time of 1 s to 15 min in an aqueous polymer dispersion comprising at least one water-soluble and/or water dispersible (meth)acrylic block copolymer comprising at least one olefinic unsaturated monomer (a) having a metal ion coordinating group, at least one olefinic unsaturated monomer (b) different from monomer (a) and having a cross-linking group B and diphenylethylene incorporated by polymerization. The metal substrate is thereby not treated by etching substances prior to the autophoretic coating. The invention further relates to a corresponding coating agent and a multilayer paint finish comprising the corresponding autophoretically deposited layer.
