Abstract:
A curable coating composition, comprising(a) a compound having at least one carbamate group or terminal urea group that is prepared by reacting together:(1) a compound comprising a carbamate or terminal urea group or a group that can be converted to a carbamate or terminal urea group and a group that is reactive with (a)(2) and(2) a lactone or a hydroxy carboxylic acid,(b) a component selected from the group consisting of:(1) a resin comprising active hydrogen-containing functional groups that are reactive with component (c),(2) a compound having at least one carbamate group or terminal urea group that is prepared by reacting together:(A) a compound comprising a carbamate or terminal urea group or a group that can be converted to a carbamate or terminal urea group and a group that is reactive with isocyanate functionality and(B) a polyisocyanate,(3) a compound having at least one carbamate group or terminal urea group that is prepared by reacting together:(A) a compound comprising a carbamate or terminal urea group or a group that can be converted to a carbamate or terminal urea group and an isocyanate group and(B) a compound having at least two groups reactive with isocyanate functionality, and mixtures thereof; and(c) a curing agent that is reactive with compound (a) and component (b),wherein said carbamate group has a structure ##STR16## in which R is H or alkyl, and further wherein said terminal urea group has a structure ##STR17## in which R' and R"" are each independently H or alkyl, or R' and R"" together form a heterocyclic ring structure.
