INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS

摘要

An interlayer for laminated glass is provided which is capable of improving the flexural rigidity of laminated glass, is capable of improving the sound insulation properties of laminated glass, and is capable of suppressing the formation of flow marks. An interlayer for laminated glass according to the present invention is provided with: a first layer which includes a thermoplastic resin; and a second layer which includes a thermoplastic resin. The second layer is provided to the first surface side of the first layer. The first layer includes silica particles. The glass transition temperature of the first layer is lower than that of the second layer. The tanδ of the first layer at 200˚C is at least 0.8.
