Material comprising an opaque coating deposited by sputtering

Abstract

The invention relates to a material comprising a substrate coated with a functional absorbent coating comprising, starting from the substrate, a first dielectric coating, a first absorbent layer, a second dielectric coating, a second absorbent layer, and a third dielectric coating. The first and second absorbent layers are selected from metallic layers or metal nitride layers based on metals selected from niobium, chromium, nickel, titanium, and zirconium, with at least one of these absorbent layers being a metal nitride layer.
