Abstract: A method for obtaining a curved laminated glazing unit, includes applying an enamel coating to a part of a first face of a first glass sheet so as to create at least one enameled zone and at least one unenameled zone, applying a sacrificial layer to a part, called the sacrificial zone, of a first face of a second glass sheet, simultaneously bending the first and second glass sheets, the sacrificial zone being disposed at least in line with at least one part of an enameled zone, removing the sacrificial layer, either during the bending or after the bending step, and laminating the first and second glass sheets by a thermoplastic interlayer.

Abstract: A process for obtaining a material including a glass sheet, includes providing a glass sheet including a first face coated at least partly by an essentially mineral first coating, the face having at least one first zone and at least one second zone, the at least one first zone having a higher emissivity than that of the second zone, then applying, on at least one portion of the second zone, a sacrificial layer including a resin, then heat treating the coated glass sheet at a temperature of at least 550° C., during which step the sacrificial layer is removed by combustion.

Abstract: A method for producing a glazed unit having a glass substrate which bears a mineral coating which forms a discontinuous surface made up of discrete patterns, the substrate provided with the coating remaining transparent, wherein the thickness of the mineral coating is not constant, with each thickness value of the coating producing a characteristic color in reflection, said discrete patterns having locally controlled variable heights. The method includes the deposition, in discrete patterns, of a thickness of between 5 and 60 μm of a liquid precursor of the mineral coating by an etched roller having locally calibrated cavities of different depths, followed by a heat treatment at a temperature of between 30° and 800° C. for 30 s to 1 h.

Abstract: A method of making a laminated glazing including at least two glass sheets bonded to each other by an adhesive interlayer, the method including, prior to assembling the laminated glazing, digital printing of one face, intended to be inside the laminated glazing, of at least one of the two glass sheets after their possible forming/bending, and/or of at least one face of the adhesive interlayer, by a homogeneous organic ink with a viscosity between 1 and 50 mPa·s including 50 to 99% by weight of ultraviolet-curable resin and 0.05 to 20% by weight of scattering particles, and then curing the organic ink under illumination with ultraviolet radiation.

Abstract: A process for manufacturing a laminated glazing that includes at least a first glass sheet and a second glass sheet, includes printing a face of the first glass sheet intended to be oriented toward the second glass sheet with a liquid enamel which is dried at a temperature not exceeding 400° C., then bending the first and second glass sheets together in contact with one another in their relative position of destination in the laminated glazing, by heating at a softening temperature of the glass, wherein the liquid enamel is an aqueous silicate paint including a refractory powder of pigments and a silicate binder powder, in the absence of glass frit, and wherein a weight ratio of pigments to silicates is greater than 1.
