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.
