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.
A coating composition comprising from about 50 to about 95 parts by weight of an air drying unsaturated oil-modified resin and from about 50 to about 5 parts by weight of an unsaturated melamine condensate of a methylolmelamine, an acrylamide, an ethylenically unsaturated fatty acid amide and 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 and wherein the unsaturated fatty acid amide is an amide of ammonia or methylamine and an ethylenically unsaturated fatty acid containing from 4 to 32 carbon atoms and at least one allylic hydrogen atom per fatty acid moiety.
An air-drying composition comprising from about 70 to about 90 parts by weight of an air drying unsaturated oil-modified resin and from about 30 to about 10 parts by weight of an unsaturated melamine condensate of a methylolmelamine, acrylamide, an ethylenically unsaturated fatty acid amide and a C.sub.1 to C.sub.4 alcohol, wherein the methylolmelamine has at least about 5 methylol groups per melamine ring, wherein substantially all the methylol groups are condensed with acrylamide, the unsaturated fatty acid amide or the alcohol, wherein the number of acrylamide moieties of the condensate is in the range of about 1 to about 3 per melamine ring, and the number of unsaturated fatty acid amide moieties is in the range of about 0.75 to about 1.5 per melamine ring, wherein the ratio of acrylamide moieties to unsaturated fatty acid amide moieties is in the range of about 1:1 to about 3:1, and wherein the amide is a primary amide of an ethylenically unsaturated fatty acid containing from 10 to 20 carbon atoms and at least one allylic hydrogen atom per fatty acid moiety.
