Foam sheet

An interlayer film for laminated glass of the present invention is an interlayer film for laminated glass, comprising one or two or more resin layers, and comprising a first resin layer comprising a resin and a light diffusion particle, in which any resin layer in the interlayer film for laminated glass comprises a colorant.

Interlayer film for laminated glass, laminated glass, and image display system

Provided is a laminated glass capable of preventing scorching in an end part of the laminated glass. A laminated glass according to the present invention is a laminated glass including a first glass plate, a second glass plate, and an interlayer film, at least one of the first glass plate and the second glass plate being a heat ray absorbing plate glass conforming to JIS R3208:1998, each of the first glass plate and the second glass plate having a thickness of 1.9 mm or less, when a layer having a lowest glass transition temperature in the interlayer film being referred to as a layer X, the layer X containing a thermoplastic resin, a ratio of a weight average molecular weight of the thermoplastic resin in the layer X before the light irradiation test, to a weight average molecular weight of the thermoplastic resin in the layer X after the light irradiation test being 2 or less.

Laminated glass

Provided is a laminated glass capable of preventing breakage in an end part of the laminated glass under external impact. A laminated glass according to the present invention is a laminated glass including a first glass plate, a second glass plate, and an interlayer film, the interlayer film being arranged between the first glass plate and the second glass plate, the laminated glass having a portion where a lateral surface of the interlayer film is exposed, and a ratio of a weight of broken glass pieces determined by a ball drop test in a laminated glass after a dipping-light irradiation test, to a weight of broken glass pieces determined by the ball drop test in a laminated glass not having undergone the dipping-light irradiation test being 2.5 or less.
