Abstract

The invention relates to a method for manufacturing laminated glass comprising at least two sheets of glass bonded to each other by an interlayer adhesive, characterized in that it comprises, prior to the assembly of the laminated glass, a digital printing of one face intended to be inside the laminated structure, of at least one of the two glass sheets after their possible forming / bending, and / or of at least one face of the interlayer adhesive, by means of a homogeneous organic ink with a viscosity between 1 and 50 mPa·s comprising 50 to 99% by mass of UV-curable resin, and 0.05 to 20% by mass of diffusing particles, followed by curing the organic ink under ultraviolet illumination; use of laminated glass obtained by this method, as glazing for land, water, or air vehicles, or as building glazing.
