Abstract
An interlayer film for laminated glass includes first, second, and third layers containing a thermoplastic resin and a plasticizer. The cloud point of the first layer is lower than both the cloud point of the second layer and the cloud point of the third layer. Both the absolute value XA of a difference between the cloud point of the first layer and the cloud point of the second layer and the absolute value XB of a difference between the cloud point of the first layer and the cloud point of the third layer are 118° C. or more, and when a content of the plasticizer in the interlayer film for laminated glass relative to 100 parts by weight of the thermoplastic resin in the interlayer film for laminated glass is defined as Y, Y≤−0.16 XA+60 and Y≤−0.16XB+60.
