Document Type and Number:
WIPO Patent Application WO/2023/145737
Kind Code:
A1
Abstract:
The present invention provides near-infrared absorbing particles each containing an intergrowth tungsten bronze crystal wherein: the amount-of-substance ratio of cesium (Cs) to tungsten (W) contained therein (Cs/W) is not less than 0.01 but less than 0.20; the amount-of-substance ratio of oxygen (O) to tungsten (W) contained therein (O/W) is not less than 2.6 but less than 2.99; and tungsten oxide and hexagonal tungsten bronze are mingled in the form of bands.
