Patent ID: 7858193

Claim:
A heat-resistant low-E multilayer system for transparent substrates, wherein the multilayer system comprises a lower antireflection coating having a high-refringence layer, a wetting layer consisting essentially of ZnO to which a silver-based functional layer is joined, a barrier layer over the functional layer, an upper antireflection coating consisting of a layer or several partial layers and a cover coating layer or cover coating partial layers, another metal oxide layer that serves as an antiscattering layer and is located in the lower antireflection coating between the high-refringence layer and the wetting layer, wherein the antiscattering layer is a mixed oxide layer comprising NiCrO x or InSnO x (ITO) and having a thickness of at least 0.5 nm, wherein the antiscattering layer is in direct contact with the wetting layer.
