A process for manufacturing a colored laminated glazing including first and second glass sheets, the two sheets being connected together by a thermoplastic interlayer, includes depositing a stack of layers including functional layer on a face of the first and/or of the second glass sheet, liquid deposition, on a face of the first and/or of the second glass sheet, of a polymer layer including a coloring agent and polymer compounds, drying and optionally curing of the polymer layer, assembling the glass sheet, coated with the colored polymer layer, with a colorless transparent thermoplastic interlayer and with the second glass sheet, so that the colored polymer layer is in direct contact with the interlayer, degassing, and heat treatment under pressure and/or under vacuum of the laminated glass at a temperature of between 100&#xb0; C. and 200&#xb0; C.

Laminated glazing comprising a stack of layers

A subject matter of the invention is a glass-ceramic sheet provided, on at least a portion of at least one of its faces, with a coating of thin layers comprising at least one thin functional layer composed of a metal based on niobium metal Nb, or of an oxide based on a niobium oxide NbOin which x is at most 0.5, the or each thin functional layer being framed by at least two thin layers made of dielectric materials, the physical thickness of the thin functional layer or, if appropriate, the combined physical thickness of all the thin functional layers being within a range extending from 8 to 15 nm.
