Black radiation-sensitive composition, black cured film, solid-state imaging element, and method of producing black cured film

摘要

The invention provides a titanium black dispersion composition comprising:
(A) a dispersed material comprising titanium black and Si atoms;
(B) a dispersant; and
(C) an organic solvent, wherein 90% or more of the dispersed material has a particle diameter in a range of from 16 nm to 30 nm, and a content ratio of Si atoms to Ti atoms in the dispersed material, represented by Si/Ti, is from 0.20 to 0.50 by mass.
