SURFACE-TREATED INFRARED-ABSORBING FINE PARTICLES, SURFACE-TREATED INFRARED-ABSORBING FINE PARTICLE POWDER, INFRARED-ABSORBING FINE PARTICLE DISPERSION IN WHICH SAID SURFACE-TREATED INFRARED-ABSORBING FINE PARTICLES ARE USED, INFRARED-ABSORBING FINE PARTICLE DISPERSOID, AND INFRARED-ABSORBING SUBSTRATE

摘要

Provided are surface-treated infrared-absorbing fine particles that are infrared-absorbing fine particles each having a crystallite size greater than or equal to 30 nm and a surface that is coated with a coating layer that contains at least one selected from a hydrolysis product of a metal chelate compound, a polymer of the hydrolysis product of the metal chelate compound, a hydrolysis product of a metal cyclic oligomer compound, and a polymer of the hydrolysis product of the metal cyclic oligomer compound.
