A method for manufacturing a motor vehicle roof incorporating a glazing, in which at least one opacifying layer of ink(s), in particular at least one layer of colored ink(s), is applied by digital printing, in particular by inkjet, over at least 40% of the surface of one of the faces of at least one glass sheet, such that the composition of said ink(s) includes at least one glass frit, and where applicable one or more inorganic pigment(s), with a D90 value for the particle size distribution of less than 2 μm, and such that the ink(s) have a viscosity of between 1 and 50 mPa·s, the ink(s) further including a non-stick agent and/or a non-stick component and/or at least one non-stick agent and/or at least one non-stick layer being further applied to at least one layer of ink(s) and/or to at least one glass sheet.

Motor vehicle roof glazing

A process for obtaining a decorative mirror includes reflective regions forming a pattern and non-reflective regions, the process including providing a sheet of soda-lime-silica glass coated with a reflective coating on the entirety of one of the faces thereof, then applying a composition including a phosphate salt to the reflective coating, solely in application regions, the application regions being intended to become the non-reflective regions, then tempering the glass sheet, in which the glass sheet is subjected to a temperature of at least 550° C., causing the reflective coating to dissolve in the application regions so as to form the non-reflective regions in which the glass sheet is not coated.
