A corrosion inhibiting composition for application to a substrate comprising at least one corrosion inhibitor selected from a metal organic framework (MOF),

• wherein the MOF comprises metal ions or metal clusters each coordinated to one or more organic ligands to form at least a one-, two- or three dimensional network, and wherein the one or more organic ligands are selected from the group consisting of optionally substituted aryl, heteroaryl or heterocyclic compounds, wherein each of the aryl, heteroaryl or heterocyclic compounds comprise at least one exocyclic sulphur group, and the ratio of organic ligand:metal is at least 2:1.

A process for preparing a corrosion inhibiting coating composition for application to a substrate comprising forming a composition by admixing a film-forming organic polymer and at least one corrosion inhibitor selected from a metal organic framework (MOF),

• wherein the MOF comprises metal ions or metal clusters each coordinated to one or more organic ligands to form at least a one-, two- or three dimensional network, and wherein the one or more organic ligands are selected from the group consisting of optionally substituted aryl, heteroaryl or heterocyclic compounds, wherein each of the aryl, heteroaryl or heterocyclic compounds comprise at least one exocyclic sulphur group.

A coated substrate comprising a substrate coated with a corrosion inhibiting composition comprising a metal organic framework (MOF),
