Substance combinations which contain (1) an inorganic salt of nitrous acid, (2) a water-insoluble polysubstituted phenol, (3) an aliphatic ester of a dihydroxybenzoic acid, and (4) a tocopherol plus optionally (5) a suitable water vapor-volatile bicyclic terpene or an aliphatically substituted naphthalene which promotes sublimation of the components present in the respective substance combination, especially in air at a relatively high atmospheric humidity, and the use of such substance combinations as vapor phase corrosion inhibitors in packaging or in storage in closed spaces for protection of the conventional metals for use such as iron, chromium, nickel, tin, zinc, aluminum, copper and their alloys against atmospheric corrosion are described. |
