Claim:
1. A method for producing a color filter, comprising: a step (i) of forming a photosensitive coloring composition layer on a substrate using a photosensitive coloring composition; a step (ii) of exposing the photosensitive coloring composition layer using light with a wavelength of more than 350 nm to 380 nm or less; a step (iii) of carrying out alkali development on the photosensitive coloring composition layer after exposure; and a step (iv) of exposing the photosensitive coloring composition layer after alkali development using light with a wavelength of 254 nm to 350 nm, in the stated order, wherein the photosensitive coloring composition contains a polymerization initiator (a) with an absorption coefficient at 365 nm in methanol of 1.0×10 a polymerization initiator (b) with an absorption coefficient at 365 nm in methanol of 1.0×10 a compound (c) which has an unsaturated double bond, an alkali-soluble resin (d), and a coloring material comprising a pigment (e), and with respect to the total solids content of the photosensitive coloring composition, the content of the polymerization initiator (a) is 1.5 mass % to 10 mass %, and the content of the polymerization initiator (b) is 1.5 mass % to 7.5 mass %.
