Claim:
1. A nonaqueous coating material composition comprising (A) at least one polyhydroxyl group-containing compound, (B) at least one polyisocyanate group-containing compound having free or blocked isocyanate groups and (D) at least one catalyst based on a zinc-amidine complex which is prepared by reacting one or more zinc(II) biscarboxylates with an amidine of the formula (I) or with a mixture of two or more amidines of the formula (I) wherein R wherein component (B) has at least one structural unit of the formula (II) and/or at least one structural unit of the formula (III), wherein R is alkyl, cycloalkyl, aryl or aralkyl, it being possible for the carbon chain to be interrupted by nonadjacent oxygen, sulfur or NRa groups, wherein Ra is alkyl, cycloalkyl, aryl or aralkyl, R′ is hydrogen, alkyl or cycloalkyl, it being possible for the carbon chain to be interrupted by nonadjacent oxygen, sulfur or NRa groups, wherein Ra is alkyl, cycloalkyl, aryl or aralkyl, X, X′ are linear and/or branched alkylene or cycloalkylene radicals having 1 to 20 carbon atoms, R″ is alkyl, cycloalkyl, aryl, or aralkyl, it being possible for the carbon chain to be interrupted by nonadjacent oxygen, sulfur or NRa groups, wherein Ra is alkyl, cycloalkyl, aryl or aralkyl, n is 0 to 2, m is 0 to 2, m+n is 2, and x, y are 0 to 2, and wherein the coating material composition comprises (S) at least one monomeric aromatic optionally substituted carboxylic acid comprising a carboxyl group in conjugation with a π-electron system.
