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 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.
