WIPO Patent Application WO/2021/117596
Kind Code:
A1
Abstract:
Provided is a laminated glass interlayer film that can suppress the occurrence of foaming at an end portion of a laminated glass and can improve the transparency of the laminated glass without performing high-temperature and high-pressure treatment by using an autoclave. The laminated glass interlayer film according to the present invention, which has a structure having one layer or two or more layers, comprises a first layer, wherein when a specific compression creep test is performed on a test sample A, which is obtained by cutting the first layer and has a diameter of 8 mm and a thickness of 0.8 mm, the amount of change in the thickness of the test sample A before and after the compression creep test is 50-325 μm.
