| abstract |
A transparent coated substrate with rather high reflectance, especially for use as in exterior glazing panels for buildings or automotives, is provided by a substrate carrying a coating stack comprising a pyrolytically-formed main layer containing oxide of tin and an outer layer comprising TiO 2 , whereby the so-coated substrate has a reflectance (RL) of more than 10 %. The coated substrate advantageously shows photocatalytic and hydrophilic properties. |
