Document Type and Number:
WIPO Patent Application WO/2021/015048
Kind Code:
A1
Abstract:
This coloring composition contains coloring agent A1 which contains dye A having cation AX+ and anion AZ- and has a dye structure, and ionic compound B which is a salt of cation BX+ and anion BZ-, wherein ionic compound B has a specific absorbance of 5 or less in a maximum absorption wavelength in the wavelength range of 400-700 nm, contains 40 mass% or more of coloring agent A1 in the overall solid content of the coloring composition, and the number of moles of cation AX+ of dye A, the number of moles of anion AZ- of dye A, and the number of moles of anion BZ- of ionic compound B satisfy a relationship represented by formula: 1.05 ≤ {(number of moles of anion AZ- of dye A + number of moles of anion BZ- of ionic compound B) / number of moles of cation AX+ of dye A} ≤ 5.00. This film, this color filter, this solid-state imaging element, and this image display device use the coloring composition.
