Abstract:
A water-borne coating composition comprisingan emulsion resin obtained by emulsion polymerization of an &agr;,&bgr;-ethylenically unsaturated monomer mixture comprising not less than 65% by weight of a (meth)acrylate ester whose ester-forming moiety contains 1 or 2 carbon atoms and having an acid value of 3 to 50 and a urethane compound represented by the general formula (1) or (2): â€ƒin formulas, R1, R2, R3, R4 and R5 may be the same or different and each represents a hydrocarbon group, R1 represents a hydrocarbon group which may optionally have a urethane bond, R3 represents a branched or secondary hydrocarbon group, n is a number not less than 2, j is a number not less than 1 in the general formula (1) or a number not less than 2 in the general formula (2) and k and m each is a number within the range of 1 to 500, 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.
