ABSTRACT:
Water-borne reaction products of (a) carboxyl-functional polymers; (b) polyepoxides; and (c) tertiary amines are blended with (d) carboxyl-functional polymers having an acid number dissimilar to that of (a). The resulting products are useful as film-forming components of coating compositions which can be spray-, flow-, dip-, roller-, or electro-coated and are especially useful for spray coating the inside of two-piece tin-plated steel cans of beverages and food. The coating compositions are useful as such or can be crosslinked with crosslinking agents such as a nitrogen resin.
