  • Etherified phosphoric acid ester of epoxy resin
    Patent number: 4801628
    Abstract: A non-water dispersible, oxirane-defunctionalized, etherified, phosphoric acid ester of an epoxy resin is useful in enhancing the adhesion of aqueous thermosetting coating compositions useful as a varnish or white coating for drawn and ironed aluminum containers. The epoxy resin ester is prepared by reacting(a) an epoxy resin having an epoxy equivalent weight of at least about 190;(b) orthophosphoric acid in an amount of 0.2 to 0.45 equivalents per equivalent of epoxy resin;(c) at least about 0.65 equivalents, per equivalent of epoxy resin, of a reactive hydroxyl-functional compound having at least one hydroxyl group reactive with an oxirane group of said epoxy resin, said hydroxyl-functional compound being a solvent for said epoxy resin and for the non water-dispersible, defunctionalized, etherified, phsophoric acid epoxy resin ester reaction product; and(d) water in an amount of 0-20% of the weight of the orthophosphoric acid.
