Abstract

Provided are a coloring composition capable of producing a film with suppressed occurrence of striation, and a method for producing a film. The coloring composition includes a coloring agent A, a resin B, a polymerizable compound C, a photopolymerization initiator D, and an organic solvent E, in which the organic solvent E includes an ester-based solvent E1 having a surface tension at 25° C. of from 25 mN/m to 35 mN/m, an organic solvent E2 having a surface tension at 25° C. of less than 25 mN/m, a ratio of a mass of the ester-based solvent E1 to the mass of the organic solvent E2 is 80:20 to 30:70 in terms of the ratio of the mass of the ester-based solvent E1:the mass of the organic solvent E2, and the organic solvent E contains 50% by mass or more of a combination of the ester-based solvent E1 and the organic solvent E2 with respect to the total mass of the organic solvent E.
