Materials comprising an opaque coating deposited by sputtering

Abstract

The invention relates to a material comprising a substrate coated with an opaque coating including, from the substrate, a first dielectric coating, a first absorbent layer, a second dielectric coating, a second absorbent layer, a third dielectric coating, a third absorbent layer, and a fourth dielectric coating. Each dielectric coating comprises at least one dielectric layer selected from oxides, nitrides, or oxynitrides of one or more elements selected from titanium, silicon, aluminum, zirconium, tin, and zinc. The first, second, and third absorbent layers are selected from metallic layers and metallic nitride layers based on at least one metal selected from niobium, chromium, nickel, titanium, zirconium, zinc, and tin.
