Abstract: A method for obtaining a laminated curved glazing, includes a. providing a first glass sheet, covered on at least part of one of its faces with a stack of thin layers, b. depositing, on a part of a surface of the stack of thin layers, a layer of enamel, the deposition being carried out by screen-printing an enamel composition including refractory particles having a diameter of at least 20 μm in a proportion by volume of at least 0.5%, but no particles having a diameter greater than 80 μm, c. bending the first glass sheet, the stack of thin layers located under the enamel layer being completely dissolved by the enamel layer at least at the end of the bending, and then d. laminating the first glass sheet with an additional glass sheet with an lamination interlayer, so that the enamel layer faces the interlayer.

Abstract: A method for obtaining a laminated curved glazing, particularly for a motor vehicle windscreen or roof. The method includes the deposition (b) of an enamel layer on a stack of thin layers deposited on a first glass sheet as well as the deposition (c), at least on the enamel layer, of refractory particles based on oxides, of metals or carbides, at least one dimension of which is larger than 30 μm. The stack of thin layers is completely dissolved by the enamel layer at the end of a bending procedure (d) carried out before laminating (e) the first glass sheet with an additional glass sheet by a lamination interlayer.

Abstract: A method for producing a curved laminated glazing, for a windscreen or roof of a motor vehicle includes providing a first glass sheet, coated on at least one part of one of its faces with a stack of thin layers, depositing, on one part of the surface of the stack of thin layers in a zone to be cleared, a washable dissolving layer, a pre-firing after which the stack of thin layers located under the washable dissolving layer is dissolved by the washable dissolving layer, creating a cleared zone, the removal of the washable dissolving layer by washing, the deposit, at least on one part of the cleared zone, of an opaque mineral layer, the curving of the first glass sheet and of an additional glass sheet, together or separately, and the laminating of the first glass sheet with an additional glass sheet using a lamination interlayer.

Abstract: A method for obtaining a laminated bent glazing, particularly for a motor vehicle windscreen or roof includes (b) depositing, on a part of the surface of a stack of thin layers deposited on a first glass sheet, in a zone referred to as zone to be demarginated, a washable dissolving layer, a pre-firing at the end of which the stack of thin layers located under the washable dissolving layer is dissolved by the washable dissolving layer, creating a demarginated zone, eliminating (d) the washable dissolving layer by washing, bending (e) the first glass sheet and an additional glass sheet, together or separately, laminating (g) the first glass sheet with an additional glass sheet by a lamination interlayer having an opaque zone arranged facing the demarginated zone.
