Document Type and Number:
WIPO Patent Application WO/2022/239452
Kind Code:
A1
Abstract:
A heat-ray reducing membrane (11) equipped with an anti-fogging function according to the present invention is such that indium tin oxide (ITO) particles and a glycerin compound serving as an anti-fogging agent are uniformly dispersed in a transparent resin, the ratio ((%Ts)/(%Tv)) of the solar transmittance (%Ts) to the visible light transmittance (%Tv) is less than or equal to 0.83, and the water contact angle is less than or equal to 20 degrees. The membrane (11) includes 0.8 g/m2 to 5 g/m2 of ITO particles and 0.04 g/m2 to 1.4 g/m2 of the glycerin compound, wherein the ITO particles are such that the specific surface area via BET method is greater than or equal to 30 m2/g, the luminance * as defined via the CIE 1976L*a*b* color system is less than or equal to 30. The membrane (11) also has a dark blue tone where the chromaticity a * is less than 0 and the chromaticity b*is less than 0, and the glycerin compound is a glycerin fatty acid ester or the like.
