Abstract

L’invention concerne un matériau comprenant un substrat transparent revêtu d’un empilement de couches comprenant au moins une couche métallique fonctionnelle à base d’argent et au moins deux revêtements diélectriques, chaque revêtement diélectrique comportant au moins une couche diélectrique, de manière à ce que chaque couche métallique fonctionnelle soit disposée entre deux revêtements diélectriques. L’empilement comprend : - un revêtement à base d’oxyde de titane comprenant au moins une couche à base d’oxyde de titane située au-dessus et au contact d’une couche métallique fonctionnelle à base d’argent présentant une épaisseur supérieure à 3 nm, - une couche à base d’oxyde de zinc et d’étain située au-dessus et au contact de la couche à base d’oxyde de titane.The invention relates to a material comprising a transparent substrate coated with a stack of layers comprising at least one silver-based functional metallic layer and at least two dielectric coatings, each dielectric coating comprising at least one dielectric layer, so that that each functional metal layer is placed between two dielectric coatings. The stack comprises: - a coating based on titanium oxide comprising at least one layer based on titanium oxide located above and in contact with a functional metallic layer based on silver having a thickness greater than 3 nm, - a layer based on zinc oxide and tin located above and in contact with the layer based on titanium oxide.
