Patent ID: 6995208

Claim:
A clearcoat coating composition, comprising (a) a least one member selected from the group consisting of (1) an acrylic polymer having both secondary hydroxyl functionality and functionality selected from the group consisting of carbamate functionality, urea functionality, and both carbamate and urea functionality and (2) a mixture of a first acrylic polymer with secondary hydroxyl functionality and a second acrylic polymer with functionality selected from the group consisting of carbamate functionality, urea functionality, and both carbamate and urea functionality, wherein said acrylic polymer or acrylic polymers of (a) have weight average molecular weights of at least about 2400; (b) a carbamate-functional or urea-functional material that is the reaction product of (1) a compound comprising a primary carbamate or primary urea group and an hydroxyl group and (2) a compound that is reactive with hydroxyl groups on a plurality of molecules of compound (1), but that is not reactive with the carbamate or urea groups on compound (1); and (c) a crosslinking component comprising a crosslinker reactive with active hydrogen groups.
