Water-borne coating composition and method of forming multilayer coating film

摘要

The present invention provides a water-borne coating composition excellent in smoothness and film appearance. A water-borne coating composition comprising: an emulsion resin obtained by emulsion polymerization of an alpha,beta-ethylenically unsaturated monomer mixture and a urethane compound represented by the general formula (1) or (2): wherein the content of said urethane compound is 0.01 to 20% by weight on the solid basis relative to the resin solid in the coating composition. A method of forming a multilayer coating film comprising: applying a water-borne base coating to an article to be coated and then applying a clear coating thereonto, followed by curing by heating, wherein said water-borne base coating is the above-mentioned water-borne coating composition.
