Coated metal reinforcement element and coating materials

A coated metal reinforcement element for a polymeric or elastomeric material comprising:

• a metal reinforcement element having a metal surface;
• and a coating for the reinforcement element comprising a polymer deposited from a solution comprising a solvent selected from the group consisting of an aqueous solvent, alcoholic solvent and organic solvent and compatible with and co-polymerizable with said material to be reinforced, and bearing functional groups covalently bonded with the outward directed first functional groups of a mono- or multi-molecular layer of a bifunctional adhesion promoter intercalated between said metal and said coating and bound to said metal by its second functional groups.
