Abstract
Epoxy phosphate-carboxyl copolymers substantially free of epoxy functionality and aqueous coatings containing the same are disclosed. These copolymers are formed by copolymerizing monoethylenically unsaturated monomers, including carboxyl-functional monomer, in an organic solvent solution containing an epoxy-functional epoxy phosphate, there being at least 5% of carboxyl-functional monomer and at least 10% of total monomers present in the copolymer. The copolymer is converted into a water soluble salt with volatile amine and phenoplast resins are preferably used to provide at least part of the curing agent.
