Abstract
A solar control coated substrate with high reflectance (RL) and comprises a pyrolytically-formed coating layer containing oxides of tin and antimony in a Sb/Sn molar ratio of from 0.03 to 0.16, characterized in that the coating layer further contains additives comprising at least one element selected form the group consisting of aluminum, chromium, cobalt, iron, manganese, magnesium, nickel, vanadium, zinc, and zirconium and is free from fluorine, whereby the so coated substrate has a reflectance of at least 10%. The invention covers a process for making such a coated substrate and a glazing panel incorporating such a coated substrate.
