Aqueous dispersion type resin composition and an aqueous coating composition containing the same

摘要

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.
