The invention relates to a method for obtaining a curved laminated glazing, in particular for a windshield or a roof of a motor vehicle. The method comprises a deposition step (b) of depositing a washable dissolving layer (14) on a portion of the surface of the thin-layer stack (12) deposited on the first glass sheet (10) in a region referred to as the "region to be delimited" (16), a pre-baking (c) at the end of which the thin-layer stack (12) located below the washable dissolving layer (14) is dissolved by said washable dissolving layer (14) forming a delimited region (17), and a delimited region (17) in which the thin-layer stack (12) located below the delimited region (17) is deposited on the portion of the surface of the thin-layer stack (12) deposited on the first glass sheet (10). The first glass sheet (10) and the additional glass sheet (20) are bent (e) together or separately by washing to remove (d) the washable dissolving layer (14), and the first glass sheet (10) and the additional glass sheet (20) are laminated (g) by means of a lamination interlayer (30) such that the opaque region (32) of the lamination interlayer (30) is arranged facing the delimiting region (17).
本发明涉及一种用于获得弯曲层压窗玻璃的方法,特别地用于机动车辆的挡风玻璃或车顶。该方法包括沉积步骤(b),在被称为“待划界区域”(16)的区域中,在沉积在第一玻璃板(10)上的薄层叠层(12)表面的一部分上沉积可洗溶解层(14),预烘烤(c),在该预烘烤(c)结束时,位于可洗溶解层(14)下方的薄层叠层(12)被所述可洗溶解层(14)溶解,形成划界区(17),通过洗涤去除(d)可洗溶解层(14),一起或单独地弯曲(e)第一玻璃板(10)和附加玻璃板(20),借助层压夹层(30)将所述第一玻璃板(10)与附加玻璃板(20)层压(g),使得所述层压夹层(30)的不透明区域(32)面向划界区域(17)布置。
