Document Type and Number:
WIPO Patent Application WO/2012/014655
Kind Code:
A1
Abstract:
The present invention provides a near-infrared reflective film and a near-infrared reflector provided with the same, which provide excellent manufacturing cost performance, can be used over large areas, exhibit excellent flexibility, and have high visible light transmittance. The near-infrared reflector is characterized in that, in an infrared film in which high refractive index layers and low refractive index layers are alternately laminated on a support body, the refractive index difference between adjacent high refractive index layers and low refractive index layers is at least 0.3, and at least one of the high refractive index layers and low refractive index layers contains a metal oxide and a polysaccharide thickener.
