MATERIALS THAT INCLUDE A TWO-LAYER FUNCTIONAL COATING THAT HAS TWO SILVER-BASED LAYERS AND AN ELEMENT MADE OF AN ABSORBENT LAYER

Abstract

The present invention relates to a material comprising a transparent substrate coated with a functional coating sequentially comprising, starting from the substrate, alternating layers of two continuous silver-based functional metal layers and three dielectric coatings. The first dielectric coating comprises a layered element comprising: - the first layer containing silicon selected from the nitride, oxide or oxynitride layers, - a discontinuous silver-based layer directly deposited on said first silicon-based layer and which includes nanometric silver particles, - a second layer containing silicon selected from nitride, oxide or oxynitride layers directly deposited on the discontinuous silver-based layer.
