Title:
WAVELENGTH-SELECTIVELY PERMEABLE LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2018/135504
Kind Code:
A1
Abstract:
Provided is a wavelength-selectively permeable laminated glass which permits the permeation of light that is in a specific wavelength range and has an effect to prevent myopia and which has a low transmittance of ultraviolet ray having a shorter wavelength than the specific wavelength range. Provided is a wavelength-selectively permeable laminated glass equipped with a light direction changing sheet which can change the direction of at least a portion of light that travels from the outside of a room toward the inside of the room to allow the permeation of the portion of the light, a first glass plate which is arranged outside of the room relative to the light direction changing sheet, a first adhesive layer which can bond the light direction changing sheet to the first glass plate, a second glass plate which is arranged inside of the room relative to the light direction changing sheet, and a second adhesive layer which can bond the light direction changing sheet to the second glass plate, wherein the transmittance T longer than 315 nm and equal to or shorter than 400 nm of light having a wavelength of longer than 315 nm and equal to or shorter than 400 nm is 3% or more and the transmittance T equal to or shorter than 315 nm of light having a wavelength of equal to or shorter than 315 nm is 60% or less.
