Abstract

This invention relates to a water-thinnable dispersion of one or more cationically modified and urethane-modified (meth)acrylic copolymers, which are produced by the solution polymerisation of unsaturated monomers which are polymerisable by a radical mechanism, or of a mixture of such monomers. Coating media based on this dispersion are particularly suitable for the production of base coats in multi-layer coatings, particularly in the coating of vehicles and vehicle parts.
