Abstract
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.
Claims18
An interlayer film for laminated glass, comprising at least one resin layer,
- wherein the interlayer film comprises a first resin layer comprising a resin and a light diffusion particle, and
- any resin layer in the interlayer film for laminated glass comprises a colorant,
- wherein a concentration of the light diffusion particle in the first resin layer is 15% by mass or more,
- wherein the haze of a laminated glass produced by using two sheets of clear glass according to JIS R3202 (2011) is 55% or more, and
- wherein a relationship according to the following expression (1):
- 500≤C×T≤3600 (1)
- is satisfied, wherein a concentration of the light diffusion particle in the first resin layer is C (% by mass) and a thickness of the first resin layer is T (μm).
A laminated glass comprising paired glass members and an interlayer film for laminated glass, the interlayer film being placed between the paired glass members and comprising at least one resin layer, comprising a first resin layer comprising a resin and a light diffusion particle,
- a concentration of the light diffusion particle in the first resin layer being 15% by mass or more,
- at least any of the paired glass members being colored by a colorant,
- wherein the haze of the laminated glass is 55% or more, and
- wherein a relationship according to the following expression (1):
- 500≤C×T≤3600 (1)
- is satisfied, wherein a concentration of the light diffusion particle in the first resin layer is C (% by mass) and a thickness of the first resin layer is T (μm).
