摘要: Method for providing corrosion protective coatings for metal surfaces. The coatings contain conventional coating components to which are added at least one zinc or lead salt of five- or six-membered heterocyclic compounds substituted by at least one hydroxyl or mercapto group and the ring includes at least one nitrogen atom and at least two conjugated double bonds, of which at least one has the formation. ##STR1## as corrosion inhibitors.
