Light-transmitting substrate, process for producing the same, and building and vehicle
WO 2002034687 A1
A light-transmitting substrate which is coated on one side with a water-and-oil repellent film and on the other side with a hydrophilic film having antifogging properties, wherein the water-and-oil repellent film is made of a perfluoroalkylalkylsiloxane and the hydrophilic film is a photocatalyst layer. The substrate is effective in improving the view through windows of a building or vehicle in a rainy day. Durability can be improved by forming a silica primer layer between the light-transmitting substrate and the photocatalyst layer.
