Intermediate film for laminated glass, and laminated glass
First Claim
1. An interlayer film for laminated glass, comprising 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, the first resin layer having a Young'"'"'s modulus of lower than or equal to 0.05 GPa, andbeing provided with a second resin layer layered on a second surface opposite to the first surface of the plastic layer or being provided with no second resin layer on a second surface opposite to the first surface of the plastic layer,when a first interface between the plastic layer and the first resin layer on a section in a thickness direction of the interlayer film is observed, a proportion of a length of the plastic layer that is not in contact with the first resin layer is less than or equal to 75%, based upon 100% of a whole length of the plastic layer in the first interface.

Abstract
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%.
