A laminated glazing includes an outer sheet of clear glass and an inner sheet of clear glass, which are joined to one another by an interlayer of plastic, includes the succession of the following elements, from the inside to the outside of the glazing: the inner sheet of clear glass, a stack of layers reflecting infrared radiation between 780 nm and 2500 nm, the interlayer including successively a) a first thin sheet including a layer of a polymer compound or of a varnish, the polymer compound or the varnish including a dye, the dye absorbing substantially all of the light within the visible region and being substantially transparent to the infrared, b) a second thin sheet of an untinted plastic, the outer sheet of clear glass.

Laminated glazing reflecting infrared

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 process for the manufacture of a colored laminated glazing including at least two glass sheets connected together by a thermoplastic interlayer, includes deposition, by the liquid route, on a first glass sheet, of a polymeric layer including a coloring agent and polymeric compounds, drying and optionally curing of the polymeric layer, assembling of the glass sheet, coated with the colored polymeric layer, with a colorless transparent thermoplastic interlayer and with the second glass sheet, so that the colored polymeric layer is in direct contact with the interlayer, degassing, during which the air trapped between the glass sheets and the thermoplastic interlayer is removed, and heat treatment under pressure and/or under vacuum of the laminated glass at a temperature of between 60 and 200&#xb0; C., during which the coloring agent present in the polymeric layer migrates toward the thermoplastic interlayer and during which the laminated glazing is assembled.
