An oxide coating composition and a process for enhancing adhesion between a metal conducting layer and an in organic material or polymeric resin material using the oxide coating composition. The process includes the steps of applying the oxide coating composition to the metal conducting layer and bonding the inorganic material or polymeric resin material to the metal conducting layer. The oxide coating composition comprises (a) an alkali; (b) an oxidizing agent; (c) an acid; and (d) a corrosion inhibitor comprising a nitrogen heterocyclic compound;
