Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
Coating composition comprising polyol-containing polymer, at least one cross-linking agent reactive with hydroxyls, and at least one reactive diluent of the formula ##STR6## wherein R 1 is alkylene of 1 to about 6 carbon atoms; R 2 is alkyl or alkylhydroxy or alkylene alkyl ether of 1 to about 20 carbon atoms; and R 3 is alkyl of 1 to about 10 carbon atoms, aryl of 6 to 10 carbon atoms, alkaryl of 7 to 10, carbon atoms, or aralkyl of 7 to 10 carbon atoms which R 1 , R 2 and R 3 may be substituted with hydroxy, with the proviso that the reactive diluent contains at least two reactive hydroxyl groups.
Claim 2
Dependent Claim
114 words
Coating composition comprising polyol-containing polymer, at least one cross-linking agent reactive with hydroxyls, and at least one reactive diluent of the formula ##STR6## wherein R 1 is alkylene of 1 to about 6 carbon atoms; R 2 is alkyl or alkylhydroxy or alkylene alkyl ether of 1 to about 20 carbon atoms; and R 3 is alkyl of 1 to about 10 carbon atoms, aryl of 6 to 10 carbon atoms, alkaryl of 7 to 10, carbon atoms, or aralkyl of 7 to 10 carbon atoms which R 1 , R 2 and R 3 may be substituted with hydroxy, with the proviso that the reactive diluent contains at least two reactive hydroxyl groups.
