Abstract

A method of producing organic-inorganic hybrid infrared absorbing particles includes a dispersion liquid preparing step of preparing a dispersion liquid containing infrared absorbing particles, a dispersant, and a dispersion medium; a dispersion medium removing step of removing the dispersion medium from the dispersion liquid by an evaporation; a raw material mixture liquid preparing step of preparing a raw material mixture liquid containing the infrared absorbing particles collected after the dispersion medium removing step, a coating resin material, an organic solvent, an emulsifying agent, water, and a polymerization initiator; a stirring step of stirring the raw material mixture liquid while cooling; and a polymerizing step of polymerizing the coating resin material after deoxygenation treatment which reduces an amount of oxygen in the raw material mixture liquid.
