Abstract:
A topcoat coating derived from an aqueous, curable coating composition comprising:(a) a carbamate-functional grafted acrylic polymer that comprises the reaction product of:(i) a first acrylic polymer having thereon a functionality (I). and(ii) a second acrylic polymer having thereon a functionality (II) that is reactive toward the functionality (I) of the first acrylic polymer,wherein at least one of the first and second acrylic polymers has thereon groups that impart water dispersibility to the grafted acrylic polymer, and further wherein at least one of the first and second acrylic polymers has thereon carbamate functionality; and(b) a compound having a plurality of functional groups that are reactive with the carbamate functionality.
