INFRARED-RAY REFLECTING SUBSTRATE AND LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2012/008587
Kind Code:
A1
Abstract:
Disclosed is an infrared-ray reflecting substrate that, when caused to be a laminated glass, the surface hue is a favorable intermediate hue that does not take on a stimulus color. The infrared-ray reflecting substrate (1) has: a transparent substrate (2); and an infrared-ray reflecting film (3) comprising at least seven alternately stacked layers of a dielectric film (3H) having a high refractive index and a dielectric film (3L) having a low refractive index. With an index of refraction of n with a thickness of d [nm] and a wavelength of λ [nm], said infrared-ray reflecting film (3) has: a first stack section (31) comprising at least 5 consecutively stacked layers of a dielectric film (311) wherein n·d/λ is 0.44 to 0.55; and a second stack section (32) comprising two consecutively stacked layers of a dielectric film (321) wherein n·d/λ is 0.03 to 0.12.
