Abstract

Official abstract text for this publication.

The present invention aims to provide an interlayer film for a laminated glass which is easily peelable without autohesion even after storage in a stacked state, and a laminated glass prepared using the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of protrusions on at least one surface, the surface having an arrangement density of the protrusions of 3 protrusions/mm 2 or more, and the protrusions having an area ratio of 15 to 75% to the surface.

First claim

Opening claim text (preview).

The invention claimed is: 1. An interlayer film for a laminated glass, having a large number of protrusions on at least one surface, wherein the surface has an arrangement density of the protrusions of 3 protrusions/mm 2 or more, wherein the protrusions have an area ratio of 15% to 75% to the surface, and wherein the protrusions each have an arithmetical mean height Sa on the surface of 200 nm or more as measured in conformity with ISO 25178. 2. A laminated glass including: a pair of glass plates; and the interlayer film for a laminated glass according to claim 1 interposed between the pair of glass plates.
