AQUEOUS RESIN COMPOSITION, AQUEOUS COATING MATERIAL, AND ARTICLE EQUIPPED WITH CURED COATING FILM MADE FROM SAID AQUEOUS COATING MATERIAL

摘要

Provided is an aqueous resin composition characterized by being produced by dispersing a self-emulsifying aqueous resin (C) in an aqueous medium, wherein the self-emulsifying aqueous resin (C) is produced by encapsulating at least one macropolyol (B) selected from the group consisting of polycarbonate polyol, polyester polyol, polyether polyol, polylactone polyol, a dimer diol and bisphenol A modified with a polyoxyalkylene in a polymer (A) produced by polymerizing a monomer mixture that contains an unsaturated monomer (a1) having a carboxyl group as an essential component. The aqueous resin composition can be used as a resin for an aqueous coating material. An aqueous coating material comprising the aqueous resin composition and a curing agent enables the production of a cured coating film having excellent coating film appearance, excellent adhesion to a base and excellent alcohol resistance and therefore can be used for a wide variety of articles including automobile bodies, industrial machines and plastic articles.
