Abstract
Official abstract text for this publication.
Disclosed are coating material compositions comprising at least one polyhydroxyl group-containing compound (A), at least one polyisocyanate group-containing compound (B) having free and/or blocked isocyanate groups, at least one catalyst (D) based on a zinc-amidine complex which comprises the reaction product of 1.0 moles of at least one zinc(II) biscarboxylate with more than 2.0 moles of at least one amidine where R 5 =hydrogen and R 1 , R 2 , R 3 , and R 4 are each identical or different radicals, R 1 and R 3 being hydrogen or an alkyl radical or an aryl radical, and R 2 and R 4 being an alkyl radical or an aryl radical, and at least one monomeric aromatic, optionally substituted carboxylic acid (S) whose carboxyl group is in conjugation with a π-electron system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coating material composition comprising at least one polyhydroxyl group-containing compound (A), at least one polyisocyanate group-containing compound (B) having free and/or blocked isocyanate groups, at least one catalyst (D) based on a zinc-amidine complex which comprises the reaction product of 1.0 moles of one or more zinc(II) biscarboxylates with more than 2.0 moles of an amidine of the formula (I) or with more than 2.0 moles of a mixture of two…
