Intermediate Film for Laminated Glass, and Laminated Glass

INTERMEDIATE FILM FOR LAMINATED GLASS, AND LAMINATED GLASS (© European Patent Office)

There is provided an interlayer film for laminated glass with which the adhesivity between a plastic layer and a resin layer can be heightened and the handling properties of laminated glass can be enhanced. The interlayer film for laminated glass according to the present invention includes a plastic layer with a Young's modulus of higher than or equal to 1 GPa and a first resin layer layered on a first surface of the plastic layer, and is provided with a second resin layer layered on a second surface opposite to the first surface of the plastic layer or is provided with no second resin layer on a second surface opposite to the first surface of the plastic layer, and when a first lamination interface between the plastic layer and the first resin layer on a section in the thickness direction of the interlayer film is observed, the proportion of the length of a portion, which is not brought into contact with the first resin layer, of the plastic layer in the first lamination interface to 100% of the whole length of the plastic layer in the first lamination interface is less than or equal to 75%.
