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.
