ABSTRACT:
A waterborne coating composition comprising 5-70 weight percent solids of a curing agent and 30-95 weight percent solids of a hydroxy functional acrylic copolymer further comprising 20-70 weight percent of a vinyl aromatic, 0-40 weight percent of a hydroxy functional monomer, 0-70 weight percent of other polymerizable compounds, and 10-80 weight percent of a reaction product of a monoepoxyester and an unsaturated acid functional monomer wherein the copolymer is prepared via skew feed polymerization having a plurality of feed streams charged to a reactor and one feed stream contains 5-60 weight percent of the unsaturated acid functional monomer, 40-95 weight percent of the reaction product of a monoepoxyester and an unsaturated acid functional monomer, and 0-55 weight percent of the other polymerizable compounds.
