摘要： A zirconium nitride powder which has a specific surface area of 20 to 90 m2/g as measured by a BET method, has a peak corresponding to zirconium nitride but does not have a peak corresponding to zirconium dioxide, a peak for lower zirconium oxide or a peak corresponding to lower zirconium oxynitride in an X-ray diffraction profile, and the light transmittance X at 370 nm is at least 18%, the light transmittance Y at 550 nm is 12% or less and the ratio (X/Y) of the light transmittance X at 370 nm to the light transmittance Y at 550 nm is 2.5 or more in the transmission spectra of a dispersion that contains the powder at a concentration of 50 ppm.

摘要： The present invention provides a powder for forming a black light-shielding film having a specific surface area of 20 to 90 m2/g, which is measured by the BET method, comprising zirconium nitride as a main component, and containing magnesium and/or aluminum. If containing the magnesium, the content of the magnesium is 0.01 to 1.0% by mass relative to 100% by mass of the powder for forming a black light-shielding film, and if containing the aluminum, the content of the aluminum is 0.01 to 1.0% by mass relative to 100% by mass of the powder for forming the black light-shielding film.

摘要： A zirconium nitride powder having a volume resistivity of 107 Ω·cm or more in the state of the pressurized powder body hardened at a pressure of 5 MPa, and a particle size distribution D90 of 10 μm or less when ultrasonically dispersed for 5 minutes in a state of being diluted with water or an alcohol having a carbon number of which is in a range of 2 to 5. Also, the zirconium nitride powder is dispersed in an acrylic monomer or an epoxy monomer to prepare a monomer dispersion. Further, the zirconium nitride powder is dispersed in a dispersing medium as a black pigment and further a resin is mixed to prepare a black composition.
