Title:
NEAR-INFRARED REFLECTIVE FILM AND NEAR-INFRARED REFLECTOR
Document Type and Number:
Japanese Patent JP2012071446
Kind Code:
A
Abstract:
To provide a near-infrared refractive film which uses an aqueous coating liquid for refractive index formation, achieves low production costs, enables stacking a larger area, and has a high near-infrared reflectance, a high visible-light transmittance and excellent durability, and a near-infrared reflector provided with the near-infrared reflective film.
The near-infrared reflective film has at least one unit composed of a high-refractive-index layer and a low-refractive index layer on a substrate. At least one of the high- and low-refractive-index layers contains particles of a metal oxide having a volume average particle size of ≤100 nm, a lithium compound, and a water-soluble polymer.
