<p>A transparent substrate has a low emission IR and/or solar radiation reflective layer stack with an upper anti-reflection layer comprising a lower tin, zinc, titanium, bismuth or aluminum oxide film and an upper mixed zinc and aluminum oxide film. A transparent substrate has a low emission IR and/or solar radiation reflective layer stack comprising a lower anti-reflection dielectric layer, one or more silver-based functional layers, preferably one or more metallic protection layers on and/or under the silver-based layer(s) and an upper anti-reflection metal oxide layer, the novelty being that the upper layer comprises a lower SnO2, ZnO, TiO2, Bi2O3 or Al2O3 film and an upper film of a mixed zinc and aluminum oxide, especially of ZnAl2O4 type spinel structure.</p> |
