摘要

Surface-treated infrared absorbing fine particles having excellent heat-resistance and excellent infrared absorbing properties, surface-treated infrared absorbing fine particles powder containing the surface-treated infrared absorbing fine particles, infrared absorbing fine particle dispersions and infrared rays using the surface-treated infrared absorbing fine particles It is to provide an absorbent particulate dispersion and a method for producing them. The surface of the infrared absorbing fine particles is at least one selected from hydrolysis products of metal chelate compounds, polymers of hydrolysis products of metal chelate compounds, hydrolysis products of metal cyclic oligomer compounds, and polymerization products of hydrolysis products of metal cyclic oligomer compounds. It provides surface-treated infrared absorbing fine particles coated with a coating film comprising a.
