SOLAR RADIATION SHIELDING MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/207555
Kind Code:
A1
Abstract:
This solar radiation shielding member is characterized by comprising, on a transparent substrate, a low irradiation film in which a first dielectric film, a first metal film, a second dielectric film, a second metal film, a third dielectric film, a third metal film and a fourth dielectric film are sequentially laminated. This solar radiation shielding member is also characterized in that: the first dielectric film comprises a dielectric layer A which contains silicon and nitrogen and is arranged directly on the transparent substrate, and a dielectric layer B which contains titanium and oxygen and is arranged on the dielectric layer A; the dielectric layer A has an optical film thickness of 12-86 nm; the first dielectric film, the second dielectric film and the third dielectric film have crystalline dielectric layers that respectively serve as the uppermost layers; the crystalline dielectric layers have an optical film thickness of 5-54 nm; and the first metal film, the second metal film and the third metal film are Ag films that respectively have the crystalline dielectric layers directly below themselves.
