Abstract
The present invention provides a near-infrared reflective film and a near-infrared reflector, which can be used over large areas and are flexible, and have low haze and high visible light transmittance. The near-infrared reflective film comprises at least one unit composed of a high refractive index layer and low refractive index layer on a substrate, and is characterized in that the refractive index difference between an adjacent high refractive index layer and low refractive index layer is at least 0.1, and said high refractive index layer contains at least one type of compound (A) selected from: 1) a rutile-type titanium oxide having a volume-average particle diameter of not more than 100 nm; 2) a water-soluble polymer; and 3) the following group of compounds. Group of compounds: a carboxyl group-containing compound, hydroxamic acids, pyridine derivatives.
