Abstract
A substrate coated on one of its faces with a stack of thin layers having reflection properties in the infrared and/or in solar radiation, including two metallic functional layers, in particular on the basis of silver. Each of the metallic functional layers is disposed between two dielectric coatings. The coating includes at least two absorbent layers which absorb solar radiation in the visible part of the spectrum, which is disposed at least in two different dielectric coatings.
