ABSTRACT:
A resinous emulsion is prepared by copolymerizing .alpha.,.beta.-ethylenically unsaturated monomers and a crosslinking monomer which is at least difunctional, in an aqueous medium in the presence of a resin having an amphoionic group of the formula: ##STR1## wherein R represents substituted or unsubstituted C.sub.1 -C.sub.6 alkylene or phenylene and Y is --COOH or --SO.sub.3 H, or in the presence of a resin having the above said amphoionic group and a polymerizable .alpha.,.beta.-unsaturated bonding. The thus obtained emulsion is useful for the obtainment of crosslinked polymer microparticles to be incorporated in a high solid coating composition or for the preparation of aqueous coating composition because of having contained no harmful emulsifier or surfactant.
