    Abstract: A material includes a transparent substrate coated with a stack of thin layers successively including an alternation of three silver-based functional metal layers and of four dielectric coatings so that each functional metal layer is positioned between two dielectric coatings. Absorbent material is present between the first functional layer and the second functional layer, in a total thickness Abs2 such that 1.0≤Abs2≤5.0 nm and/or absorbent material is present between the second functional layer and the third functional layer, in a total thickness Abs3 such that 1.0≤Abs3≤5.0 nm. Additionally, absorbent material is present between the face of the substrate and the first functional layer in a total thickness such that 0.0

    Abstract: A material includes a transparent substrate coated on one face with a stack of thin layers successively including, starting from the face, an alternation of three silver-based functional metal layers denoted, starting from the substrate, first, second and third functional layers respectively Ag1, Ag2 and Ag3, and of four dielectric coatings denoted, starting from the substrate, M1, M2, M3 and M4, with optical thicknesses respectively To1, To2, To3 and To4. Each functional metal layer is positioned between two dielectric coatings. The geometrical thickness of the second functional layer Ag2 is less than the thickness of the first functional layer Ag1. The geometrical thickness of the second functional layer Ag2 is less than the thickness of the third functional layer Ag3. The dielectric coating M2 exhibits a lower optical thickness To2 than the optical thicknesses To1, To3 and To4 respectively of the dielectric coatings M1, M3 and M4.
