Patent ID: 7740940

Claim:
A coated article comprising: a) a polymer substrate and adhered to the substrate surface b) an organometallic film comprising a polymeric metal oxide with alkoxide and hydroxyl groups that covalently bond to the substrate and in which the metal has electrons in the f orbital or is niobium; and in which the polymeric metal oxide is of the structure: [M(O) x (OH) y (OR) z ] n where M is the metal, R is an alkyl group containing from 1 to 30 carbon atoms; x+y+z=V the valence of M; x is at least 1, y is at least 1, z is at least 1; x=V−y−z; y=V−x−z; z=V−x−y; n is greater than 2; c) adhered to the organometallic film a different film derived from an organophosphorus acid that has groups reactive with the alkoxide and hydroxyl groups of the organometallic film and in which the organophosphorus acid is selected from a phosphoric acid, a phosphonic acid, and a phosphinic acid and derivatives thereof.
