Abstract:
A curable coating composition, comprising(a) a component selected from the group consisting of:(1) a compound having at least one carbamate group or urea group that is prepared by a step of reacting a mixture comprising:(A) a compound comprising a carbamate or urea group or a group that can be converted to a carbamate or urea group and a group that is reactive with (a)(1)(B) and(B) a polyisocyanate,(2) a compound having at least one carbamate group or urea group that is prepared by a step of reacting a mixture comprising:(A) a compound comprising a carbamate or urea group or a group that can be converted to a carbamate or urea group and an isocyanate group and(B) a compound having at least two groups reactive with isocyanate functionality,and mixtures thereof;(b) an acrylic polymer comprising active hydrogen-containing functional groups that are reactive with component (c), and(c) a curing agent that is reactive with compound (a) and compound (b),wherein said carbamate group has a structure ##STR13## in which R is H or alkyl, and further wherein said urea group has a structure ##STR14## in which R' and R"" are each independently H or alkyl, or R' and R"" together form a heterocyclic ring structure.
