Transparent substrate provided with a heat-reflective multilayer stack

摘要

The subject of the invention is a flexible or rigid, transparent substrate provided with a stack of thin layers, which includes at least one functional layer predominantly based on silver Ag placed between two coatings of dielectric material, at least one of the coatings comprising a layer predominantly based on aluminium nitride AlN. The functional layer or at least one of the functional layers is modified by incorporating at least one minor metal M other than Ag and/or the said AlN-based layer, or at least one of them, is modified by incorporating at least one metal M' in a minor amount compared with the aluminium.
