摘要

Heat-shielding fine particles having high visible permeability and at the same time excellent heat shielding effect and stable weather resistance, a heat shielding particulate dispersion using the heat shielding particulates, a coating liquid for heat shielding films and a heat shielding shield using the same, a heat shielding resin film, a heat shielding particulate dispersion To provide. In the infrared shielding fine particles containing calcium lanthanum boride fine particles represented by the general formula Ca _x La _1-x B _m , the fine particle shape of the calcium lanthanum boride fine particles is obtained by using the 1) X-ray incineration scattering method. 2) a plate-like cylindrical shape, or a flat ellipsoid shape, wherein the inclination value Ve is -3.8≤Ve≤-1.5, and the aspect ratio d / h is at least one selected from 1.5≤d / h≤20. Provided are heat ray shielding fine particles and infrared ray shielding particle dispersion liquid using the particles, a coating agent for heat ray shielding film, and an infrared ray shielding film, heat ray shielding resin film and heat ray shielding particle dispersion using these.
