Abstract
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° C., during which the coloring agent present in the polymeric layer migrates toward the thermoplastic interlayer and during which the laminated glazing is assembled.
