Provided is an interlayer film for laminated glass capable of making bluish fogging less likely to occur. An interlayer film for laminated glass according to the present invention contains a pigment, and in the interlayer film for laminated glass, a value YId obtained by subtracting a yellow index YIp calculated from parallel light transmittance from a yellow index YIt calculated from total light transmittance is −1.0 or more.

Intermediate film for laminated glasses, and laminated glass

A thermoplastic filmis a thermoplastic film comprising a light-emitting layer, wherein the light-emitting layercomprises a thermoplastic resin and a light-emitting material that emits light by being irradiated with excitation light, and a change in yellowness of laminated glass obtained by bonding two sheets of clear glass in accordance with JIS R 3211 (1998) having a thickness of 2.5 mm with the thermoplastic film interposed therebetween after conducting a light resistance test for 2000 hours based on JIS R3205 2005 is 4 or less. The present invention provides a thermoplastic film comprising a light-emitting material, in which the emission intensity is unlikely to lower even when the thermoplastic film is exposed to ultraviolet rays for a long period of time.

Thermoplastic film and laminated glass

A thermoplastic filmis a thermoplastic film comprising a light-emitting layer, wherein the light-emitting layercomprises a thermoplastic resin and a light-emitting material that emits light by being irradiated with excitation light, and when laminated glass obtained by bonding two sheets of clear glass in accordance with JIS R 3211(1998) having a thickness of 2.5 mm with the thermoplastic film interposed therebetween is irradiated, from one surface, with excitation light, which the light-emitting material is capable of absorbing, in a quantity of light of 7 mW/cm, a difference between luminance A observed on a side of the one surface and luminance B observed on a side of the other surface, (A&#x2212;B), is 5 cd/mor more. According to the present invention, a thermoplastic film such that when laminated glass is made using the thermoplastic film, information is displayed relatively strongly on one surface, and the information is displayed relatively weakly on the other surface, and a laminated glass comprising this thermoplastic film can be provided.

An interlayer film for laminated glass of the present invention comprises at least an absorption region in which a skin absorption energy rate (X) of a laminated glass is 25% or less, provided that the laminated glass is produced using two clear glass plates having a solar transmittance of 87.3% based on JIS R 3106.

Interlayer for laminated glass, laminated glass, and glass structure

Foam sheet

Provided is an interlayer film for laminated glass capable of suppressing double images, and making the moisture resistance of the laminated glass exposed to high temperature and high humidity uniform at one end and the other end of the interlayer film. The interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass, being wedge-like shaped and containing an amphiphile or a surfactant, and when a high temperature and high humidity test for laminated glass is executed, a whitening distance at the one end and the other end of the interlayer film is 15 mm or less, and when a whitening distance at the one end of the interlayer film is more than 0 mm, a value of (whitening distance at the other end of the interlayer film&#xd7;thickness of the other end of the interlayer film)/(whitening distance at the one end of the interlayer film&#xd7;thickness of the one end of the interlayer film) is 0.70 or more.

Interlayer film for laminated glass, and laminated glass

An interlayer film for laminated glass of the present invention comprises at least an absorption region in which a skin absorption energy rate (X1) of a laminated glass is 25% or less, provided that the laminated glass is produced using two clear glass plates having a solar transmittance of 87.3% based on JIS R 3106.

The light emitting structure of the present invention includes a sheet-shaped structure which absorbs excitation light and emits light with wavelength conversion and which has a maximum emission wavelength of 400 nm or more; and an antireflection material provided on a side surface of the sheet-shaped structure.
