Material comprising an opaque coating deposited by sputtering

Abstract

The invention relates to a material comprising a substrate coated with a functional absorbent coating, including, 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 metallic layers based on metals selected from niobium, chromium, nickel, titanium, and zirconium. The mass percentage of these elements in each absorbent layer is greater than 65%.
