ABSTRACT:
An optically clear, electrically conductive, transparent coating on a substrate and a method of coating are disclosed. The coating comprises a first transparent layer deposited as TiO.sub.x on the substrate, where x preferably has a value within the range of 1.3 to 1.7, a layer of silver or gold deposited on the first layer, and a third transparent layer deposited as TiO.sub.x on the second layer, where x preferably has a value within the range of 1.3 to 1.7. The coating is deposited under vacuum in a partial pressure of oxygen on a rigid transparent substrate such as glass or a flexible plastic substrate and the resultant coated substrate used in electrically heated windows.
