Abstract (en)

[origin: WO2021219961A1] The invention relates to a material comprising a substrate (30) coated on one face (29) with a stack of thin layers (14) comprising at least one metallic functional layer (140) and comprising: - an underlayer of zinc-based oxide, ZnO (129), of between 0.3 and 4.4 nm; - a dielectric underlayer of titanium-based oxide, TiOx (127), which is located under and in contact with said underlayer of zinc-based oxide, ZnO (129), with a physical thickness of the dielectric underlayer of titanium-based oxide TiOx (127) of between 5.0 and 50.0 nm; - an overlayer of zinc-based oxide, ZnO (161), of between 2.0 and 10.0 nm: - a dielectric overlayer (165).
