Abstract (en)
[origin: WO2022058685A1] The invention relates to laminated glazing (1) with liquid crystal variable transmission, comprising a first glass substrate (10) and a second glass substrate (11), at least one liquid crystal cell (2), a first lamination interlayer (30) placed between the first glass substrate (10) and the liquid crystal cell (2), and a second lamination interlayer (40) placed between the second glass substrate (11) and the liquid crystal cell (2), the glazing being characterised in that said first interlayer (30) is a film made of a polymeric material and in that said second interlayer (40) is made of a transparent adhesive material (OCA) that, prior to the manufacture of the glazing, takes the form of a liquid and is crosslinkable.
