<p>A cationic thermosetting latex, coating compositions prepared therefrom, and the process for providing a protective coating are disclosed. The thermosetting latex comprises a blocked isocyanate curing agent and a cationic acrylic latex which is prepared by copolymerizing ethylenically unsaturated monomers, at least one of which contains an active hydrogen group, in an acidic medium in the presence of a cationic surfactant, of which the gegen-ion is derived from certain phosphorous-containing acids. Such latices, when formulated into coating compositions, provide corrosion-resistant coatings.</p> |
