Abstract (en)
[origin: WO2023002111A1] The invention relates to a laminated glazing having at least a first glass substrate (10) and a second glass substrate (11), at least one functional film (2) disposed between the two glass substrates, and at least a first laminating interlayer film (3) between the first glass substrate (10) and the functional film (2), and at least a second laminating interlayer film (4) between the second glass substrate (11) and the functional film (2), characterized in that the functional film (2) has at least one layer of a transparent adhesive material (20), referred to as OCA, which is viscoelastic so as to be able to deform in terms of thickness during the process of laminating the glazing.
