Abstract

A coloring composition is provided which is less likely to remain on a pattern of other colors as residues and can inhibit occurrence of coating defects. Also provided are a colored pattern, a color filter, a method of producing a color filter, a pattern forming method, a solid-state imaging device, and an image display device, each using the coloring composition. The coloring composition contains a resin (A) having a dye structure, in which in the peak area of the total molecular weight distribution of the resin (A) as measured by gel permeation chromotography, the proportion of the peak area of a component having a molecular weight of 20,000 or more is 10% or less.

the dye structure of the resin (A) is a structure derived from a dye selected from the group consisting of a xanthene dye, a cyanine dye, a squarylium dye, a quinophthalone dye, and a subphthalocyanine dye, and
the resin (A) contains a polymerizable group having an ethylenically unsaturated bond in the side chain of the resin (A) after polymerization.

2. The coloring composition according to claim 1 , wherein the weight average molecular weight of the resin (A) is 4,000 to 15,000.

11. The coloring composition according to claim 4 ,
wherein the photopolymerization initiator (D) is an oxime compound.

12. The coloring composition according to claim 7 ,
wherein the resin (A) is a resin having a dye structure that includes the constitutional unit represented by the General Formula (A).

13. The coloring composition according to claim 1 ,
wherein the ethylenically unsaturated bond is a (meth)acryloyl group.
