  • Publication number: 20230108923
    Abstract: A black material of the present invention consists of a zirconium nitride powder containing yttrium. The amount of the yttrium is 1.0% by mass to 12.0% by mass with respect to a total 100% by mass of the zirconium nitride powder and the yttrium. In a transmission spectrum obtained from a dispersion in which the concentration of the zirconium nitride powder containing yttrium is 50 ppm, assuming that the light transmittance at a wavelength of 550 nm is denoted by X1, and the light transmittance at a wavelength of 365 nm is denoted by X2, X1 is 7.5% or less, X2 is 25% or more, and X2/X1 is 3.5 or more.
