ABSTRACT:
Aqueous coatings particularly adapted for interior sanitary can use are provided in which the resin solids are constituted by a solution copolymer of a resinous polyepoxide esterified to be epoxy-free with from about 0.3 to about 1.5 moles of at least one monocarboxylic acid containing conjugated ethylenic unsaturation per mol of polyepoxide. This esterified polyepoxide is Diels Alder adducted with from 3% to 10%, based on the weight of the copolymer, of an ethylenically unsaturated dicarboxylic acid, and this adduct is copolymerized with from 10% to 50%, based on the weight of the copolymer, of monoethylenically unsaturated nonreactive monomer containing a terminal ethylenic group, such as styrene or vinyl toluene. This copolymer can be dispersed in water with the aid of a volatile base and aminoplast or phenoplast resin can be incorporated.
