The present invention provides a pigment fine particle which is a white pigment having a heat shielding effect, and the life of the coating film can be improved by applying the pigment fine particle. A pigment fine particle for coating, comprising 50 to 95% by mass of Al2O3, 5 to 40% by mass of ZrO2, and 0 to 10% by mass of SiO2 as a chemical component, and an oxidation amount of 80% by mass or more of the total amount of Al2O3 and ZrO2 It is composed of an aluminum-zirconia co-crystal and has a particle diameter D50 of 0.1 to 80 μm. The pigment microparticles have a high heat-shielding effect and are excellent in abrasion resistance. |
