ABSTRACT:
An unsaturated condensate of an alkoxymethylmelamine, an allylic alcohol and an acrylamide wherein the alkoxymethyl group contains from 1 to 4 carbon atoms, wherein the ratio of allylic moieties to acrylamide moieties is in the range of about 3:1 to about 1:3, wherein there is at least about 0.75 allylic moieties and no more than about 3 acrylamide moieties per melamine ring and wherein the total of allylic moieties and acrylamide moieties is in the range of about 2 to about 4 per melamine ring. The unsaturated condensates are used in high solids unsaturated coating systems containing unsaturated oil-modified resins.
