Abstract
Abstract A process of making water-soluble coating compositions is described characterized in that (A) an adduct of an alpha-beta ethylenically unsaturated dicarboxylic acid or anhydride with olefinic, unaltered or polymerized, oil fatty acids, or mixtures of such acids with other unsaturated carboxylic acids or natural esters thereof, or hydroxy-free polyol esters thereof; (B) a polyhydroxy compound; and (C) a water-insoluble, hardenable phenol-aldehyde condensation product of a phenol substituted in the ortho- or para-position with an alkyl radical having at least three carbon atoms, are combined at an elevated temperature to form a homogeneous resinous body; and the resin thereafter made water-soluble through the addition of a water-soluble nitrogen base. The water-soluble coating compositions are particularly useful for electrodeposition providing films having improved surface characteristics and corrosion resistance.
