Abstract
Abstract The invention is a substrate having a surface coated with a singular metal oxide film wherein the metal consists essentially of titanium and tin and the film is made from a liquid mixture of a titanate, a tin compound, and an anhydrous organic liquid. The substrate may be glass and the film applied by pyrolytic decomposition of the liquid mixture in air. Preferably, the film has a refractive index of greater than 2.2 and no visible light absorption to give it an optimal neutral appearance.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
32 words
A substrate carrying an oxide film of titanium and
tin, wherein said oxide film is made from a liquid mixture
of an alkyl titanate, a tin compound, and an anhydrous
organic liquid.
Claim 2
Dependent Claim
28 words
A substrate according to claim 1, wherein the film
is made by pyrolytic decomposition of the liquid mixture
sprayed with air onto a surface of a hot substrate.
Claim 3
Dependent Claim
24 words
A substrate according to claim 1 or claim 2, wherein
the metal oxide film has a tin metal ion ratio of 10% to
70%.
Claim 4
Dependent Claim
30 words
A substrate according to any one of claims 1 to 3,
wherein the said titanate is selected from the group
consisting of tetra-butyl titanate, tetra isopropyl
titanate, and their mixture.
Claim 5
Dependent Claim
16 words
A substrate according to any one of the preceding
claims, wherein said tin compound is dibutyltin-diacetate.
Claim 6
Dependent Claim

A substrate according to any one of the preceding
claims, wherein said liquid mixture comprises, by volume,
40-47.5 % titanate selected from the group consisting of
tetra-butyl titanate, tetra isopropyl titanate, and their
mixture; 5-20% dibutyltin diacetate; and 40-47.5 % anhydrous
organic liquid selected from the group consisting of
kerosene, isopropyl alcohol, and their mixture.
