Document Type and Number:

WIPO Patent Application WO/2020/031558

Kind Code:

A1

Abstract:

Provided is a laminated glass interlayer that can increase adhesive force between a (meth)acryloyl polymer-including layer and an adhesion body positioned on said layer, and can increase a sound blocking property of a laminated glass. This laminated glass interlayer has a single-layer or dual-layer structure, and comprises a first layer that includes a (meth)acryloyl polymer in which polymer components have been polymerized, said polymer components including at least one type of cyclic skeleton-including (meth)acryloyl monomer selected from the group consisting of (meth)acryloyl monomers that have an aromatic skeleton, (meth)acryloyl monomers that have an alicyclic skeleton, and (meth)acryloyl monomers that have a cyclic ether skeleton, wherein per 100wt% of the polymer components, the content of the cyclic skeleton-including (meth)acryloyl monomer is 50wt% or greater.
