Claims
- 1. A tin oxide coated article comprising a transparent, haze-free tin oxide coating directly on a substrate selected from the group consisting of glass, ceramics, solid state materials, metals, an elemental filaments, wherein said tin oxide coating is formed by deposition from a liquid coating composition comprising an organotin compound which is an alkyltin trichloride, a dialkyltin dichloride, an alkyldichlorotin acetate, an alkylchlorotin diacetate, or an ester tin trichloride, and a haze-reducing additive which is a fluorocarboxylic acid or anhydride said tin oxide coated article having less than 1% haze.
- 2. A tin oxide coated article according to claim 1 wherein said substrate is glass.
- 3. A tin oxide coated article according to claim 1 wherein said organotin compound is an alkyltin trichloride.
- 4. A tin oxide coated article according to claim 3 wherein said alkyltin trichloride is monobutyltin trichloride.
- 5. A tin oxide coated article according to claim 1 wherein said haze-reducing additive is a trifluoromethylcarboxylic acid or anhydride.
- 6. A tin oxide coated article according to claim 5 wherein said trifluoromethylcarboxylic acid is trifluoroacetic acid.
- 7. A tin oxide coated article according to claim 1 wherein said haze-reducing additive also imparts a low sheet resistance to said article by doping with fluorine.
- 8. A tin oxide coated article according to claim 1 wherein said deposition is carried out by chemical vapor deposition.
- 9. A tin oxide coated article according to claim 8 in which said deposition comprises vaporizing said liquid coating composition and contacting said vapor in an oxygen-containing atmosphere with a substrate maintained at a temperature above the decomposition temperature of said vapor.
