Abstract
Coating compositions comprising an unsaturated oil modified resin and an unsaturated melamine condensate. The unsaturated melamine condensate is a condensate of a methylolmelamine, an acrylamide, an ethylenically unsaturated fatty acid amide and optionally a C.sub.1 to C.sub.10 alcohol, wherein the methylolmelamine has at least about 5 methylol groups per melamine ring, wherein substantially all the methylol groups are condensed with the acrylamide, the unsaturated fatty acid amide or the alcohol, wherein the number of the acrylamide moieties of the condensate is in the range of about 1 to about 4 per melamine ring and the number of unsaturated fatty acid amide moieties is in the range of about 0.5 to about 2 per melamine ring, wherein the ratio of the acrylamide moieties to unsaturated fatty acid amide moieties is in the range of about 1:1 to about 3:1.
