A curable coating composition containing a carbamate-functional reactive additive
is made by reacting a compound having at least one epoxy group and at least one
branched alkyl group of 5 to 30 carbons with carbon dioxide, to produce a carbonate
functional compound, and then with ammonia. The carbamate-functional reactive additive
is incorporated into a curable coating composition. The coating composition may
contain a polymer comprising active hydrogen-containing functionality other than
carbamate and a curing agent having groups that are reactive with the polymer active
hydrogen-containing functionality, wherein one or both of polymer and curing agent
comprise groups that are reactive with the carbamate group of the carbamate-functional
reactive additive. The coating composition is applied to an article and cured.
