A dispersion liquid contains modified silica particles that are obtained by reacting silica particles which are surface-treated with a compound A represented by Formula Si(R)(X), which has a reactive group, with a compound B which has a functional group reacting with the reactive group to form a bond and has an organic group, an organic solvent, and water, in which a content of water is 0.1 to 20.0 mass % with respect to a total mass of the modified silica particles. In Formula A, Rrepresents a monovalent organic group including the reactive group, Xrepresents a hydroxyl group or a monovalent hydrolyzable group, and n represents an integer of 1 to 3.

Dispersion liquid, composition, cured film, color filter, optical element, solid-state imaging element, and headlight unit

A composition includes: a compound represented by the following Formula (1); a pigment; and a solvent. In a case where a film having a thickness of 4.0 m is formed using the composition, a maximum value of a light transmittance of the film in a thickness direction in a wavelength range of 360 nm to 700 nm is lower than 40%. In Formula (1), Zrepresents an (m+n)-valent linking group, Yand Yeach independently represent a single bond or a linking group, A represents a group including a pigment adsorption portion, Prepresents a polymer chain, n represents 1 to 20, m represents 1 to 20, and m+n represents 3 to 21, at least one of Z, A, or Pincludes a photocurable group.
