Title:
FAR INFRARED-REFLECTING FILM, HEAT-BLOCKING FILM, AND HEAT-BLOCKING GLASS
Document Type and Number:
WIPO Patent Application WO/2019/198589
Kind Code:
A1
Abstract:
Provided are: a far infrared-reflecting film that comprises a substrate and a far infrared-reflecting layer containing a binder and flat conductive particles, in which the value obtained by dividing the average particle size of the flat conductive particles by the average thickness is 20 or more, the thickness y nm of the far infrared-reflecting layer is at least three times the average thickness of the flat conductive particles, the volume fraction x of the flat conductive particles in the far infrared-reflecting layer is 0.4 or more, and the product x × y of the volume fraction x and the thickness y satisfies formula A; a heat-blocking film provided with the far infrared-reflecting film; and a heat-blocking glass provided with the far infrared-reflecting film.
