摘要

A metal-nitride-containing particle which can be used for a curable composition which has excellent sedimentation resistance and excellent stability over time and which can obtain a cured film having excellent light-shielding properties. Also, a dispersion composition, a curable composition, a cured film, a color filter, a solid-state imaging device, a solid-state imaging device, an infrared sensor, a method for producing a metal nitride-containing particle, a method for producing a dispersion composition, a method for producing a curable composition, to provide. The metal nitride-containing particles contain nitrides of transition metals of Groups 3 to 11, have an average primary particle diameter of 200 nm or less, contain nitrogen atoms and atoms T, and the atoms T are oxygen atoms, chlorine atoms, and nitrogen atoms T _E is the content based on the mass of the atom T detected by the X-ray photoelectron spectroscopic analysis, T is the content based on the mass of the atom T detected by the fluorescent X-ray analysis, and T _X , it satisfies T _E / T _X 2.0.
