An aqueous thermosetting coating composition suitable for electrodeposition onto the surface of an article used as a cathode. The coating composition is an aqueous solution or dispersion of a resinous material and an organic and/or inorganic acid the resinous material being prepared by reacting (i) a secondary amine with (ii) epoxy groups pendant from a main chain of a copolymer of 5-50% by weight of an ethylenically unsaturated monomer containing epoxy groups and 50-95% by weight of one or more of vinyl or acrylic unsaturated monomers which do not contain epoxy groups and which are copolymerizable with the ethylenically unsaturated monomer. The secondary amine is employed in an amount of 0.1 - 0.8 equivalent per 1 equivalent of epoxy groups contained in said copolymer.
