The paint coating composition comprises a cationic free, functional emulsion polymer mixture adapted to be coreacted at room temperature with glycoluril to provide a cured thermoset paint film. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers, but excluding amine monomers, in an aqueous polymerization medium, followed by ion exchange of the resulting reactive emulsion polymer. Preferably, the glycoluril is processed through an ion exchange step separately or in conjunction with the reactive emulsion polymer. The resulting polymers are useful as binders in ambient cure surface coating application. |
