Patent ID: 11318719

Abstract:
The present invention aims to provide an interlayer film for a laminated glass that can, even when having a thickness at the thickest portion of 850 μm or more, exhibit sufficient deaeration properties in production of a laminated glass to provide a laminated glass with high transparency, and a laminated glass produced using the interlayer film for a laminated glass. Provided is an interlayer film for a laminated glass having a large number of recesses on at least one surface, the interlayer film for a laminated glass having a thickness T (μm) measured in conformity with JIS K-6732 (1996) and a maximum height roughness Ry (μm) measured in conformity with JIS B-0601 (1994) at a thickest portion, the thickness T and the maximum height roughness Ry satisfying the following expressions (1) and (1′): Ry≥0.020×T+16.6  (1),T≥850  (1′).
