Abstract

The invention relates to coating material compositions comprising an isocyanate group-containing component, a hydroxyl group-containing component, a zinc-imidazole-carboxylate complex and a monomeric aromatic carboxylic acid, and also to the use of a zinc-imidazole-carboxylate complex in the presence of a monomeric aromatic carboxylic acid as a catalyst system for the urethane reaction in coating material compositions.
