INFRARED CUT MATERIAL, INFRARED CUT MATERIAL DISPERSION LIQUID, COMPOSITION FOR FORMING INFRARED CUT FILM, AND INFRARED CUT FILM

摘要

An infrared ray cut-off material is formed of phosphorus-doped antimony tin oxide powder, in which a content of antimony in terms of SbO 2 is not less than 14 parts by mass and not more than 30 parts by mass with respect to 100 parts by mass of the infrared ray cut-off material, a content of phosphorus in terms of PO 2.5 is not less than 1 part by mass and not more than 25 parts by mass with respect to 100 parts by mass of the infrared ray cut-off material, and a balance other than antinomy oxide and phosphorus oxide is tin oxide.
