INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS
There is provided an interlayer film for laminated glass with which the flexural rigidity of laminated glass can be enhanced and the sound insulating properties of laminated glass can be enhanced. The interlayer film for laminated glass according to the present invention includes first, second, and third layers containing a thermoplastic resin and a plasticizer, Cloud point 1 concerning the first layer is lower than each of Cloud point 2 concerning the second layer and Cloud point 3 concerning the third layer, each of Absolute value XA of a difference between the Cloud point 1 and the Cloud point 2 and Absolute value XB of a difference between the Cloud point 1 and the Cloud point 3 is 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, XA, XB, and Y satisfy the equations of Y≤−0.16XA+60 and Y≤−0.16XB+60.
