Abstract

The purpose of the present invention is to provide an infrared shielding film, method for producing same, and infrared shield provided with the infrared shielding film, whereby it is possible to maintain stable infrared shielding performance, visible light transmittance, flexibility, and transparency over time. This infrared shielding film having at least one unit constituted of a high-refractive-index layer and a low-refractive-index layer comprising metal oxide particles atop a substrate is achieved when (i) the high-refractive-index layer and / or the low-refractive-index layer comprises a temperature-responsive polymer as a binder component or (ii) the high-refractive-index layer comprises either a cellulose compound or polyvinyl acetal resin as a binder component, and the low-refractive-index layer comprises a binder component different from that of the high-refractive-index layer.

Description

technical field

[0001] The invention relates to an infrared shielding film, a manufacturing method of the infrared shielding film and an infrared shielding body. Background technique

[0002] In recent years, interest in energy-saving measures has increased, and from the viewpoint of reducing the load on air conditioners, there has been an increasing demand for infrared shielding films installed on window glass of buildings or vehicles to block the transmission of solar heat rays.

[0003] As a method of forming an infrared shielding film, it has mainly been proposed to form a laminated film having a structure in which high-refractive-index layers and low-refractive-index layers are alternately laminated using dry film-forming methods such as vapor deposition and sputtering. However, the dry film-forming method has problems in that a vacuum device and the like for film-forming are relatively large, the production cost is high, and it is difficult to enlarge the area, and the...
