摘要

Solar radiation shielding fine particle dispersion containing solar radiation fine particles and thermoplastic resin having high visible light transmission, excellent heat ray shielding effect and stable weather resistance, masterbatch containing solar radiation fine particles, solar radiation shielding resin molded body, and the molded body laminated on another transparent molded body Provided is a solar radiation shielding resin laminate. A liquid solar radiation shielding fine particle dispersion in which a mixture of at least one selected from an organic solvent and a plasticizer and a solar radiation shielding particle is dispersed, or a powdered solar radiation shielding particulate dispersion material obtained by heating a liquid component from the dispersion is dispersed in a resin component It is a dispersion of shielding fine particles, and the solar radiation shielding fine particles are solar radiation shielding fine particles containing calcium lanthanum boride fine particles of the general formula Ca _x La _1-x B _m , and the value of x in the general formula is 0.001≤x≤0.800. The value of m is 5.0 ≦ m 6.3, the average dispersed particle diameter is 1 nm or more and 800 nm or less, and the calcium lanthanum boride fine particles have a predetermined shape.
