Title:
ADHESIVE LAYER-EQUIPPED FUNCTIONAL FILM FOR LAMINATED GLASS AND LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2024/048344
Kind Code:
A1
Abstract:
Provided is an adhesive layer-equipped functional film for laminated glass that makes possible the production of laminated glass configured to suppress the generation of wrinkles and interference fringe. The adhesive layer-equipped functional film for laminated glass comprises a functional film, a first adhesive layer provided on one surface of the functional film and a second adhesive layer provided on the other surface of the functional film. When the adhesive layer-equipped functional film for laminated glass is used in a laminated glass, T1, which is the thickness of the first adhesive layer, is at least 2 μm but less than 380 μm, and T2, which is the thickness of the second adhesive layer, is at least 380 μm but no more than 760 μm, and the total of T1 and T2 is 760 μm or more. The functional film has a resin layer. The phase difference of the resin layer in the thickness direction measured at a wavelength of 543 nm is 100 nm or less.
