Patent ID: 7803458

Claim:
The combination of: a substrate having a surface; and a cured layer that is a metal oxide and organic hybrid film on said substrate surface, said layer being formed from a composition comprising: a solvent system; an organometallic oligomer dissolved or dispersed in said solvent system, said organometallic oligomer comprising recurring monomers having the formula wherein: n is 3-10; each M is individually selected from the group consisting of Groups 3-5 and 13-15 metals other than silicon and having a combining valence of greater than ±2; and each R 1 is an organic moiety covalently bonded or coordinate-covalently bonded to M; and an organic polymer or oligomer having a weight-average molecular weight of at least about 150 g/mol, said organic polymer or oligomer comprising a functional group selected from the group consisting of chelating moieties selected from the group consisting of wherein: m is 1 or 2; when m is 2, then x is 0; each R 6 is individually selected from the group consisting of hydrogen and methyl groups; and each R 7 is individually selected from the group consisting of hydrogen and alkyls; and wherein said cured layer has a refractive index of at least about 1.65 at a wavelength of about 633 nm and at a thickness of about 0.5 μm.
