Abstract

The invention provides curable coating compositions comprising an aqueous dispersion comprising a stabilizing resin (P1) and a compound (P2) comprising functional groups reactable with a crosslinking agent. Compound (P2) is dispersed into stabilizing resin (P1). The coating compositions of the invention may further comprise an optional crosslinking agent (P3) which may or may not be dispersed into stabilizing resin (P1). In a particularly preferred embodiment, both the stabilizing resin (P1) and compound (P2) will comprise functional groups which are carbamate or are convertible to carbamate.
