1. A method of forming an aqueous coating composition comprising polymerizing monoethylenically unsaturated monomers in an aqueous dispersion in the presence of a dispersed epoxy resin to form an aqueous dispersion copolymer, the copolymer of said monoethylenically unsaturated monomers having a glass transition temperature in the range of about -55°

  • C. to about 105°

    C., and then mixing the aqueous dispersion of copolymer and epoxy resin formed by said polymerization with an amine-functional resin in an amount to supply a weight ratio of amino hydrogen atoms to oxirane group of from 0.2 to 1.5.
