Abstract
Abstract A novel aqueous dispersion type resin composition obtained by the method comprising polymerizing at least one alpha , beta -ethylenically unsaturated monomer in an aqueous medium containing a water soluble resin with an amphoionic group of the formula <IMAGE> (in which R and Y are defined in the specification) and in the presence of an organic initiator, the solid weight ratio of said water soluble resin to said monomer being, 10:90 to 90:10. The aqueous coating composition based on said resin composition is excellent in storage stability, application characteristics and capable of resulting a coating with excellent film properties.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
156 words
An aqueous coating composition comprising as a resinous vehicle (1) an aqueous dispersion resin composition obtained by polymerizing at least one α, β-ethylenically unsaturated monomer in an aqueous medium in the presence of a water soluble resin having an amphonic group of the formula: ##STR22## in which R is a substituted or unsubstituted C 1 to C 6 alkylene or phenylene group and Y is --COOH or --SO 3 H, said resin selected from the group consisting of an alkyd resin, a polyester resin, an acryl modified alkyd resin, an acryl modifed polyester resin, a modified epoxy resin, an acrylic resin, a melamine resin and a polyether resin, and a water insoluble organic initiator, the weight ratio of said water solouble resin in solid form to said monomer being 10:90 to 90:10, and (2) an acrylic water soluble resin having no amphionic group of the formula: ##STR23## in which R and Y are as defined above.
