Title: HEAT-RAY-SHIELDING MICROPARTICLES, HEAT-RAY-SHIELDING MICROPARTICLE LIQUID DISPERSION, COATING LIQUID FOR HEAT-RAY-SHIELDING FILM, AND HEAT-RAY-SHIELDING FILM, HEAT-RAY-SHIELDING RESIN FILM, AND HEAT-RAY-SHIELDING MICROPARTICLE DISPERSION BODY THAT USE SAID MICROPARTICLES, LIQUID DISPERSION, OR COATING LIQUID
Abstract:
The present invention provides: heat-ray-shielding microparticles that have a high visible light transparency and at the same time an excellent heat-ray-shielding effect and a stable weather resistance; a heat-ray-shielding microparticle liquid dispersion and a coating liquid for a heat-ray-shielding film that use said heat-ray-shielding microparticles; and a heat-ray-shielding film, a heat-ray-shielding resin film, and a heat-ray-shielding microparticle dispersion body that use said microparticles, liquid dispersion, or coating liquid. Provided are: heat-ray-shielding microparticles that contain calcium lanthanum boride microparticles represented by general formula CaxLa1-xBm wherein the microparticle shape of the calcium lanthanum boride microparticles is at least one shape selected from 1) a value Ve of the slope of the straight line obtained using small-angle x-ray scattering of -3.8 ≤ Ve ≤ -1.5 and 2) a flat plate cylindrical shape or oblate spheroidal shape of which the value of the aspect ratio d/h is 1.5 ≤ d/h ≤ 20; a heat-ray-shielding microparticle liquid dispersion and a coating liquid for a heat-ray-shielding film that use said microparticle; and a heat-ray-shielding film, a heat-ray-shielding resin film, and a heat-ray-shielding microparticle dispersion body that use said microparticle, liquid dispersion, or coating liquid.
