Abstract
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.
