INTERLAYER FILM FOR LAMINATED GLASS, AND LAMINATED GLASS

摘要

The purpose of the present invention is to provide an interlayer film for laminated glass, said interlayer film enabling the production of highly visible laminated glass having no bubbles and capable of exhibiting high deaerability even when using the nip roll method, and to provide laminated glass using said interlayer film for laminated glass. The present invention is an interlayer film for laminated glass, said interlayer film having a plurality of recesses and a plurality of projections on at least one surface thereof. The recesses have continuous trench-shaped bottom sections, and adjacent recesses are regularly aligned in parallel. The ratio (R/Sm×100) of the radius R of the bottom sections of the recesses having continuous trench-shaped bottom sections with respect to the interval Sm of the recesses having continuous trench-shaped bottom sections is 15% or more.
