Abstract
Abstract A metal oxide coating is formed on a vitreous or non-vitreous substrate by applying to a substrate a composition comprising an acetyl acetonate coprecipitate of two or more metals. The substrate and composition are simultaneously or subsequently heated to convert the coprecipitate on the substrate to leave a metal oxide coating which is at least partly composed of an oxidic compound containing two or more metals.
