Abstract: A composition useful as an aqueous anionic electrodepositable coating comprises a film-former of from about 67-95% by weight of a phosphated polyepoxide resin, from about 5-33% by weight of a carboxyl group-containing vinyl addition resin, and up to about 40% by weight of the film-former of a crosslinking agent.

Abstract: There are herein provided reaction products of a compound containing an ethylenically unsaturated group and a compound containing at least two reactive groups of varying reactivity. One of the reactive groups such as a mercapto group reacts through the ethylenically unsaturated group. The resulting products are useful as reactive diluents or as film-formers.

Abstract: A polyurethane crosslinker is provided by reacting a partially-blocked diisocyanate and a hydroxyl-terminated, carboxyl group-containing polyurethane precursor. The precursor is a reaction product of a diol containing a carboxyl group and another diol of high molecular weight, and a diisocyanate. The instant crosslinkers are particularly useful in water-based coating compositions for metal containers.

Abstract: An aqueous resinous dispersion and a method of coating employing the aqueous resinous dispersion are disclosed. The aqueous resinous dispersions are solubilized with base and comprise an acrylic polymer containing N-ethoxymethylacrylamide or methacrylamide moieties and an epoxy resin. The dispersion is useful for coating metal containers particularly as a coating for the interior of containers which are used for alcoholic beverages, for example, beer cans.
