摘要：A composition and process are described which are useful in treating metalsurfaces, which composition comprises an oxidizer, an acid, a corrosion inhibitor, anorganic nitro compound and, optionally, a benzotriazole with an electron withdrawinggroup in the 1-position which electron withdrawing group is a stronger electronwithdrawer than a hydrogen group, optionally, a source of adhesion enhancing speciesselected from the group consisting of molybdates, tungstates, tantalates, niobates,vanadates, isopoly or heteropoly acids of molybdenum, tungsten, tantalum, niobium,vanadium, and combinations of any of the foregoing and optionally by preferably asource of halide ions. The composition and process are useful in increasing the adhesionof metal surfaces to polymeric substances and in preserving said adhesion throughtemperature variation.
