ABSTRACT:
A process for producing an aqueous emulsion of unsaturated resin suitable for radiation curing coating compositions comprises the steps of: synthesizing polyvinyl resin having an acid value of 50 to 230 by solution polymerization, adding a monomer having both epoxy group and reactive unsaturated group to said polyvinyl resin, if necessary further mixing a monomer of above 190.degree. C in boiling point having reactive unsaturated group(s) to the above adduct, removing solvent under reduced pressure, neutralizing residual acid groups with base and dispersing the neutralized product into water.
