Title:
LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2021/100782
Kind Code:
A1
Abstract:
A laminated glass (1_1) according to the present invention is provided with: a first glass sheet (11); a second glass sheet (12); and an intermediate film (13_1). The intermediate film (13_1) has a laminated region that has: a first layer (21) in contact with the first glass sheet (11); a second layer (22) in contact with the second glass sheet (12); and a third layer (23) disposed between the first layer (21) and the second layer (22). When the relative dielectric constant of the first glass sheet (11) is defined as εg1, the relative dielectric constant of the second glass sheet (12) is defined as εg2, the relative dielectric constant of the first layer (21) is defined as εm1, the relative dielectric constant of the second layer (22) is defined as εm2, and the relative dielectric constant of the third layer (23) is defined as εm3, there are relationships of εm1<εg1, εm1<εg2, εm2<εg1, εm2εm1, and εm3>εm2.
