ABSTRACT:
The pigmented paint coating composition is based on a cationic free polymeric binder comprising a cationic free, functional emulsion polymer and glycoluril where the emulsion polymer are adapted to coreact to form a thermoset paint film, and said polymeric binder is combined with a low-cation opacifying pigment. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers but excluding amine monomers, in an aqueous polymerization medium, to produce the reactive emulsion polymer. The emulsion polymer and the glycoluril derivative are treated with ion-exchange step to produce the cation-free polymeric binder.
