WIPO Patent Application WO/2018/070461
Kind Code:
A1
Abstract:
Provided is a laminated glass intermediate film capable of suppressing blurriness in appearance caused by light and double images. Thus, a laminated glass intermediate film (11) equipped with a first layer (1) containing a thermoplastic resin and a plasticizer, and a second layer (2) containing a thermoplastic resin and a plasticizer, wherein the minimum thickness of the first layer (1) is 20μm or higher, and given that the ratio of the first layer (1) thickness at one end (11a) of the intermediate film to the thickness of the intermediate film itself at the one end (11a) is the ratio A, and the ratio of the first layer (1) thickness at the other end (11b) of the intermediate film to the thickness of the intermediate film itself at the other end (11b) is the ratio B, then the ratio B is no less than 1.1 times and no more than 1.7 times the ratio A when the wedge angle is 0.1-0.5 mrad, inclusive, the ratio B is no less than 0.8 times and no more than 1.1 times the ratio A when the wedge angle exceeds 0.5 mrad, and the plasticizer content of the first layer (1) is greater than the plasticizer content of the second layer (2).
