Abstract:
Provided are a colored composition which enables the formation of a pattern having excellent heat resistance and excellent solubility in solvents and has inhibited color migration; and a cured film, a color filter, a method for producing a color filter, a solid-state image sensor, and an image display device, each of which uses the colored composition.The colored composition includes a polymer anion having a repeating unit containing a weakly nucleophilic anionic structure, and a dye having a cationic structure, in which the weakly nucleophilic anionic structure represents an anionic structure produced by dissociating an organic acid having a lower pKa value than the pKa value of sulfuric acid.
