Document Type and Number:
WIPO Patent Application WO/2024/071338
Kind Code:
A1
Abstract:
An interlayer film for a laminated glass, the interlayer film comprising two or more resin layers in which at least one resin layer differs in glass transition temperature from the other resin layer(s), wherein, when a coordinate on a straight line extending from one end toward the other end is expressed by x [mm], then the difference between the maximum and minimum values of the thickness proportion R (x) of the low-Tg resin layer, which has a lowest glass transition temperature among the two or more resin layers, to the whole interlayer film for a laminated glass is 8% or less.
