Abstract

Provided are a coloring composition having improved heat resistance; and a cured film, a color filter, a method for producing a color filter, and a solid-state imaging element and an image display device, each of which uses the coloring composition. The coloring composition includes a dye (A) represented by the following General Formula (I) and a polymerizable compound (B). General Formula (I) is (R) m -Q-(D) n , wherein Q represents an (m+n)-valent linking group, R represents a substituent, D represents a dye residue, m represents an integer of 0 to 6, n represents an integer of 2 to 8, and (m+n) represents an integer of 2 to 8. In the case where m is 2 or more, a plurality of R's may be different from each other, and in the case where n is 2 or more, a plurality of D's may be different from each other.
