    Abstract: A composition which comprises (a) a salt of a metal (M) of a hydroxycarboxylic acid in which the OH and COOH groups are attached to the ring atoms of a fused ring system and (b) a surface coating compound or composition. The metal (M) is at least divalent and may be magnesium, calcium, barium or particularly zinc. The fused ring system is preferably a fused aromatic hydrocarbon ring system such as naphthalene. The OH and COOH groups can be attached to adjacent carbon atoms of fused hydrocarbon ring system. Zinc 3-hydroxy-2-naphthoate has been found to be particularly suitable. The composition may also include a metal oxide and/or a metal phosphate. Component (b) can be a film forming binder system, a natural oil or a grease. The composition can be coated onto the surface of a metal. The coated metal shows improved resistance to corrosion.

    Abstract: A method for the inhibition of corrosion of metals involves treatment of the metal surface with a polyester having a functional terminal group such as an amine. The polyester may be used together with other corrosion inhibitors, a useful combination being the polyester together with a hydroxy-oxime. The corrosion inhibiting material may be incorporated into a surface coating composition such as paint which is then applied to the metal surface.
