Abstract
The invention relates to a substrate (10) coated on one face (11) with a multilayer of thin films (14) with reflective properties in the infrared and/or in the solar radiation band comprising a single functional metal layer (140), in particular of silver or of a metal alloy containing silver, and two dielectric coatings (120, 160), said coatings each comprising at least one dielectric layer (122, 164), said functional layer (140) being disposed between the two dielectric coatings (120, 160), said multilayer furthermore comprising a single absorbing layer (19), characterized in that said absorbing layer (19) is a metal layer having a physical thickness in the range between 0.5 nm and 1.5 nm, or even between 0.6 nm and 1.2 nm and is situated directly on said face (11) and directly under a dielectric layer of nitride not comprising any oxygen.
