Abstract

In a heat-resistant low-emissivity (low-E) multilayer system that includes a silver layer as functional layer, for transparent substrates, in particular for window panes, which has, between the surface of the substrate and the silver layer, a high-refringence layer, in particular made of TiO2, Nb2O5 or TiNbOx, and, immediately below the silver layer, a layer essentially consisting of ZnO, a mixed oxide layer with a thickness of at least 0.5 nm, made of NiCrOx or InSnOx (ITO) that serves as antiscattering layer is placed between the high-refringence layer and the ZnO layer.
