The invention relates to coating agents that are suitable for multilayer coatings, containing organic solvents, anti-runoff agents and optionally pigments, filling materials and additives, in addition to a bonding agent/crosslinking system, comprising: A) 20 to 80 wt.% carboxyl-functional (meth)acrylic polymers and/or carboxyl-functional polyester, with an acid value of 20 to 300; B) 20 to 80 wt.% epoxide-functional crosslinking agent, whereby the sum of the wt.% of A) and B) is 100 wt.%; C) 0 to 30 wt.% polymer polyol C) in relation to the sum of weights A) and B); E) 0 to 20 wt.% additional crosslinking agents in relation to the sum of weights A), B) and C); F) 0 to 10 wt.% monoepoxide in relation to the sum of weights A) and B), and D) 0.1 to 3 wt.%, in relation to the resin solids, solid fine-particle urea compounds D) insoluble in the coating agent and previously prepared in the presence of at least part of the epoxide-functional crosslinking agent B), whereby overall percentages by weight relate to the solids. |
