COMPOSITION, CURED FILM, COLOR FILTER, LIGHT BLOCKING FILM, OPTICAL ELEMENT, SOLID-STATE IMAGING ELEMENT, HEADLIGHT UNIT, MODIFIED SILICA PARTICLES, AND METHOD FOR PRODUCING MODIFIED SILICA PARTICLES

摘要

The present invention provides a composition which has excellent development residue suppression properties. The present invention also provides a cured film, a color filter, a light blocking film, an optical element, a solid-state imaging element, a headlight unit, modified silica particles, and a method for producing modified silica particles. A composition according to the present invention contains modified silica particles and a polymerizable compound, and is configured such that: each one of the modified silica particles comprises a silica particle and a cover layer that covers the silica particle; and the cover layer contains a polymer that comprises a repeating unit represented by general formula (1).
