摘要

ATO infrared absorbing fine particles having high coloring property (high light absorption property) which has both excellent dispersibility and solar radiation shielding properties and can reduce a use amount of ATO infrared ray absorbing fine particles can be provided, wherein crystal lattice constant a is 4.736 Å or more and 4.743 or less, crystal lattice constant c is 3.187 Å or more and 3.192 Å or less, and a crystallite size is 5.5 nm or more and 10.0 nm or less, which are analyzed by an X-ray diffraction measurement result.
