Abstract
Environmental etch resistant coatings are described. The coatings are derived from aqueous, curable coating compositions comprising: PA1 (a) a carbamate-functional grafted acrylic polymer that comprises the reaction product of a first acrylic polymer and a second acrylic polymer, with at least one of the first and second acrylic polymers having groups that impart water dispersibility to the grafted acrylic polymer, and at least one of the first and second acrylic polymers having carbamate functionality; and PA1 (b) a second component comprising a compound having a plurality of functional groups that are reactive with the carbamate functionality.
