WATER-BORNE COATING COMPOSITIONS Abstract of the Disclosure Water-borne or aqueous coating compositions which are suitable for use as bondable base coats and size coats in three piece, tin-free steel beverage containers comprise blends of an aqueous dispersion of an amine solubilized interpolymer with aldehyde condensation resins. The interpolymer is prepared in the absence of mercaptans, external surfactants and external dispersion stabilizers and is formed from substituted carboxylic acid amide units; ethylenically unsaturated acid units; hardening units from monomers such as styrenes vinyl toluene or alkyl methacrylate having from 1 to 4 carbon atoms and flexibilizing units from certain alkyl acrylates or methacrylates. The interpolymers are solubilized by neutralizing or partially neutralizing the acid units of the interpolymer with monomeric amines. Aldehyde condensation resins, such as phenol aldehyde resins, amino- plast resins or mixtures thereof are especially desirable.
