摘要： Coating composition suitable for multilayer lacquering, containing, in addition to organic solvent, anti-sagging agents, optionally pigments, extenders and additives, a binder/crosslinkin agent system containing A) from 20 to 80 wt. % of carboxyl-functional (meth)acrylic copolymers and/or carboxyl-functional polyesters having an acid number of from 20 to 300, B) from 20 to 80 wt. % of epoxy-functional crosslinking agents, the percentages by weight of A) and B) adding up to 100 wt. %. C) from 0 to 30 wt. % of polymer polyol C), based on the sum of the weights of A) and B), E) from 0 to 20 wt. % of further crosslinking agents, based on the sum of the weights of A, B, and C), F) from 0 to 10 wt. % of monoepoxides, based on the sum of the weights of A) and B), and D) as anti-sagging agents, from 0.1 to 3 wt. %, based on the resin solids, of solid, finely divided urea compounds D) which have previously been prepared in the presence of at least a portion of the epoxy-functional crosslinking agent B) and which are insoluble in the coating compositions, all percentages are by weight being based in each case on the solids.
