1. A glazing, comprising:
- a transparent substrate and a stack of thin layers present on the substrate,wherein the stack of thin layers comprises(i) n functional layers having reflection properties in the infrared and/or solar radiation range, wherein n is an integer of 1 or greater;
(ii) n+1 coating layers each comprising two or more dielectric layers, wherein each dielectric layer independently comprises a dielectric material, and wherein each functional layer is between two coating layers, and(iii) at least one absorbent layer that absorbs visible light,wherein the absorbent layer is between and in direct contact with two dielectric layers of a single coating layer, andwherein the absorbent layer is a metal or a metal alloy comprising Ti, Nb, Zr, or NiCr;
a metal oxide selected from the group consisting of chromium oxide, iron oxide, substoichometric titanium oxide, and substoichometric zinc oxide;
or a metal nitride selected from the group consisting of titanium nitride, niobium nitride, zirconium nitride, chromium nitride, and NiCr nitride.

Abstract
The subject of the invention is glazing comprising at least one transparent substrate provided with a stack of thin layers consisting of an alternation of n functional layers having reflection properties in the infrared and/or the solar radiation range and of n+1 coatings composed of one or more layers made of a dielectric, so that each functional layer is placed between two coatings. At Least one layer absorbent in the visible is inserted between two layers of dielectric of at least one of the said coatings.
