Abstract
Haze-free tin oxide coatings are made from an organotin compound which ordinarily gives only hazy coatings. The improvement comprises first forming an undercoat of a haze-free tin oxide film on a substrate, preferably by decomposition of monophenyltin trichloride. Thereafter the tin oxide overcoating assumes the haze-free characteristics of the undercoat film.
