Abrégé
(EN)
The invention relates to a material comprising a transparent substrate coated on one face with a stack of thin layers successively comprising, starting from said face, an alternation of three silver-based functional metallic layers Agi, Ag2 and Ag3 and of four dielectric coatings M1, M2, M3 and M4, with optical thicknesses Eo1, Eo2, Eo3, Eo4, respectively, each dielectric coating comprising a dielectric layer or a dielectric set of layers, so that each functional metallic layer is disposed between two dielectric coatings, said material being characterised in that: - absorbant material is present between the first functional layer Agi and the second functional layer Ag2, with a total thickness Abs2, such that 1.0 < Abs2 < 5.0 nm, and/or absorbant material is present between the second functional layer Ag2 and the third functional layer Ag3, with a total thickness Abs3, such that 1.0 < Abs3 < 5.0 nm; - absorbant material is present between the face of the substrate and the first functional layer Agi, with a total thickness Abs1, such that 0.0 < Abs1 < 0.5 nm, and absorbant material is present above the third functional layer Ag3, with a total thickness Abs4, such that 0.0 < Abs4 < 0.5 nm.
