Abstract:
A coating material comprising:A) at least one hydroxyl-containing polymer, andB) at least one blocked diisocyanate and/or polyisocyanate wherein some of the isocyanate groups are blocked with dialkyl malonate,wherein the isocyanate groups of component (B) are blocked with a mixture of dialkyl malonates comprising:b1) from about 30 to about 85% by weight of at least one dialkyl malonate of the general formula (I) ##STR5##and/or at least one dialkyl malonate of the general formula (II) ##STR6##whereR.sup.1, R.sup.2, and R.sup.3 are each independently selected from aliphatic, cycloaliphatic, or araliphatic secondary alkyl radicals having at least 3 carbon atoms, andR.sup.4 is an aliphatic, cycloaliphatic, aromatic or araliphatic hydrocarbon radical,andb2) from about 70 to about 15% by weight of at least one dialkyl malonate other than component (b1),the sum of components (b1) and (b2) being in each case 100% by weight.
