Abstract
The present invention relates to a coating composition consisting of at least three components (I), (II) and (III), component (I) containing as binder (A) at least one acrylate copolymer (A1) which is dispersed or dissolved in organic, optionally water-dilutable solvent and/or one polyester resin (A2) which is dispersed or dissolved in organic, optionally water-dilutable solvent and/or one polyurethane resin (A3) which is dispersed or dissolved in organic, optionally water-dilutable solvent and/or optionally a further binder (A4), PA1 component (II) contains at least one nonblocked polyisocyanate as crosslinking agent, and PA1 component (III) contains as constituent essential to the invention an aqueous dispersion, prepared in a single- or multistage method, of a hydrophilicized polymer resin HP based on a hydrophobic polymer resin HP' and also, if desired, contains components (A1) and/or (A2) and/or (A3) and/or (A4) in aqueous dispersion. Also described is the use of the novel coating compositions for the finishing of automobile bodies and plastics parts and for automotive refinishing.
