Abstract
A transparent substrate carrying a coating stack which has undergone a bending or tempering type of heat treatment and a method of manufacturing this product, the coating stack comprising at least one metallic coating layer comprising silver or a silver alloy characterized in that before the said heat treatment, each metallic coating layer is in contact with two non-absorbent transparent dielectric coating layers, each comprising a sub-layer based on a partially oxidized combination of two metals. The product in accordance with the invention is intended for incorporation in a laminated glazing, particularly to form a vehicle windshield.
Claims41
