Abstract

The utility, as coatings, of water-thinnable, base-neutralized H.sub.3 PO.sub.4 /polyether epoxide reaction products, is improved by admixture therewith of the base-neutralized reaction products of phosphoric acid with various other kinds of epoxides. Of particular value are such mixtures in which the latter products are derived from methylol- or lower alkoxymethyl-substituted epoxides.
