Document Type and Number:
WIPO Patent Application WO/2024/034436
Kind Code:
A1
Abstract:
Provided is an intermediate film for a laminated glass that is hardly bent. An intermediate film for a laminated glass according to the present invention comprises: a first resin layer containing a thermoplastic resin; a second resin layer containing a thermoplastic resin; and an optical film. The first resin layer is disposed on a first surface side of the optical film. The second resin film is disposed on a second surface side of the optical film opposite to the first surface. The thickness T1 of the first resin layer is less than the thickness T2 of the second resin layer. The ratio of the thermal shrinkage rate A1 of the first resin layer in a direction where the thermal shrinkage rate of the first resin layer becomes maximum with respect to the thermal shrinkage rate A2 of the second resin layer in a direction where the thermal shrinkage rate of the second resin layer becomes maximum is more than 1 but not more than 5.
