ABSTRACT OF THE DISCLOSURE Process for producing metal-resin composite, and the composite resulting therefrom, are provided. The process comprises providing a solution or dispersion of a resin, for example, an epoxy resin, said solution or dispersion having dispersed therein at least one particulate metal compound, for example, an oxide, of the Group I A and II A metals of the Periodic Table, the amount of metal compound being 1-500 parts by weight per 100 parts by weight of resin, then coating the solution or dispersion on a metal substrate and heating the coated substrate to evaporate the solvent for the resin and cure the resin. The resultant metal-resin composite is cor- rosion resistant, especially under acidic conditions, since the resin layer having the Group I A or II A metal compound dispersed therein serves to control the pH on the surface of the metal substrate to within the range from 4 to 12 under acidic conditions in the atmosphere surrounding the metal- resin composite.
