Document Type and Number:
WIPO Patent Application WO/2023/126213
Kind Code:
A1
Abstract:
The invention relates to a material comprising a substrate (30) coated on one face (29) with a stack of thin layers (14) comprising a single functional metal layer (140) and two anti-reflection coatings (120, 160), wherein an anti-reflection coating that is further from the face (29) than a functional layer comprises: - a dielectric layer of aluminium and silicon nitride AlxSiyNz (165) which has an atomic proportion of aluminium with respect to the total of aluminium and silicon of between 91.0% and 55.0%, and at least one upper dielectric layer, * of nitride and/or oxide and located further from the face (29) than said dielectric layer of aluminium and silicon nitride AlxSiyNz (165), and/or * of nitride and located closer to the face (29) than said dielectric layer of aluminium and silicon nitride AlxSiyNz (165).
