Abstract

A curable coating composition is described comprising(A) a carbamate- or urea-functional compound that is the reaction product of a mixture comprising(1) a compound comprising a carbamate or urea group or a group that can be converted to carbamate or urea, and a hydroxyl functional group that is the reaction product of (a) a compound comprising a carbamate or urea group or a group that can be converted to a carbamate or urea group, and an active hydrogen group that is reactive with a lactone ring or a hydroxy carboxylic acid, and (b) a lactone or a hydroxy carboxylic acid, and(2) a compound that is reactive with hydroxyl groups on a plurality of molecules of compound (A)(1), but that is not reactive with the carbamate or urea groups on compound (A)(1),(B) a compound comprising a plurality of groups that are reactive with carbamate or urea.
