Abstract
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° C. and 200° C.
