ABSTRACT:
A process for producing an aqueous coating composition comprising an aqueous dispersion of internally crosslinked polymer microgel particles in which the microgel articles are produced by emulsion polymerisation of ethylenically unsaturated monomers including carboxyl functional monomer in an aqueous medium so as to form an aqueous dispersion of carboxyl functional addition polymer followed by reacting this polymer dispersion with a diepoxide resin having an epoxide equivalent weight between 100 and 5000 to form the crosslinked polymer microgel particles.
