Title:
INTERLAYER FILM FOR LAMINATED GLASS, AND LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2021/246506
Kind Code:
A1
Abstract:
Provided is an interlayer film for laminated glass in which it is possible to improve the seal between an interlayer film and a laminated glass member and in which it is possible to suppress optical distortion. The interlayer film for laminated glass according to the present invention comprises a first outer layer, a second inner layer, a first inner layer, a third inner layer, and a second outer layer. The interlayer film has a region X in which the first outer layer, the second inner layer, the first inner layer, the third inner layer, and the second outer layer are positioned so as to be lined up in the stated order in the thickness direction of the interlayer film. The shear storage elastic modulus of each of the second inner layer and the third inner layer at 1 Hz and 100°C is 0.2-1000 MPa (inclusive). The shear storage elastic modulus of each of the first outer layer and the second outer layer at 1 Hz and 100°C is greater than the shear storage elastic modulus of the first inner layer at 1 Hz and 100°C. The shear storage elastic modulus of each of the second inner layer and the third inner layer at 1 Hz and 100°C is greater than the shear storage elastic modulus of the first inner layer at 1 Hz and 100°C.
