Beschreibung
Zusammenfassung:	A binder composition for aqueous coatings that exhibit high gloss and superior corrosion resistance when applied to metal substrates comprising an aqueous emulsion copolymer, the copolymer including as polymerized units, at least one ethylenically unsaturated monomer and an ethylenically unsaturated strong acid monomer, such as phosphorus containing monomers, particularly phosphoethylmethacrylate; or salts thereof. Also provided is a method for achieving high gloss and superior corrosion resistance of metal substrates by coating a substrate with an aqueous coating composition comprising the binders of the present invention and drying, or allowing to dry, the aqueous composition.
