Title: METAL NITRIDE-CONTAINING PARTICLES, DISPERSION COMPOSITION, CURABLE COMPOSITION, CURED FILM, PRODUCTION METHOD FOR THESE, COLOR FILTER, SOLID-STATE IMAGING ELEMENT, SOLID-STATE IMAGING DEVICE, AND INFRARED SENSOR
Abstract:
Provided are metal nitride-containing particles capable of being used in a curable composition that has excellent anti-settling properties and excellent stability over time and is capable of obtaining a cured film having excellent light shielding properties. Also provided are: a dispersion composition; a curable composition; a cured film; a color filter; a solid-state imaging element; a solid-state imaging device; an infrared sensor; a production method for the metal nitride-containing particles; a production method for the dispersion composition; a production method for the curable composition; and a production method for the cured film. The metal nitride-containing particles: contain a nitride of a group 3–11 transition metal; have an average primary particle diameter of no more than 200 nm; and contain a nitrogen atom and an atom T. The atom T: is not an oxygen atom, a chlorine atom, or a nitrogen atom; is selected from group 13–17 elements; and fulfils TE/TX < 2.0 when the atom T content on a mass basis as detected by X ray photoelectron spectroscopic analysis is TE and the atom T content on a mass basis as detected by fluorescent X ray analysis is TX.
