ABSTRACT OF THE DISCLOSURE A novel coating process is provided herein for the pre- paration of a coherent protective layer on a substrate surface of a body, where the substrate surface comprising elemental metal or an alloy thereof. The process comprises the first step of reacting (i) a compound of a group lA metal, effective in aqueous media to convert a free carboxylic acid group to a carboxylate group with (ii) an aqueous solution consisting of water and a homopolymer of a mono- or polybasic ethylenically unsaturated acid or a copolymer of a mono- or polybasic ethylenically unsaturated acid comprising at least 40 mol % of polymerized unsaturated carboxylic acid residues, the amount of (i) being sufficient to neutralize from 5 to 20% of the acid groups of the homo- or copolymer(ii). The second step comprises applying, to the substrate surface, an aqueous solution consisting of water and the partially neutralized homo- or copolymer of a mono- or polybasic ethylenically unsaturated acid resulting from the reaction. The final step involves heat-curing the layer so formed at a temperature above 180°C.
