Document Type and Number:
WIPO Patent Application WO/2014/069506
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an optically reflective film having favorable coating properties and low haze properties (excellent film-surface uniformity); an infrared-shielding film; and an infrared shield equipped with the infrared-shielding film. This optically reflective film is an optically reflective film having a substrate and a reflective layer which at least reflects infrared light, wherein: the reflective layer has a plurality of layered refractive-index layers; one or more of the refractive-index layers have a different refractive index than that of the refractive-index layers adjacent thereto; one or more of the refractive-index layers which configure the reflective layer contain metal-oxide fine particles, a water-soluble zirconium compound, carboxylic acid, and a polyvinyl-alcohol-based resin; and the mixing ratio of the water-soluble zirconium compound and the carboxylic acid therein is 2-16:1 (water-soluble zirconium compound (solid content converted to zirconia): solid content of carboxylic acid (mass ratio)).
