Abstract:
A coloring composition includes colorants, polymerizable compounds, and a resin, in which a ratio P/M of a mass P of the colorants to a mass M of the polymerizable compounds is 0.05 to 0.35, a content of the polymerizable compounds is 25 to 65 mass % with respect to a total solid content of the coloring composition, a ratio A/B of a minimum value A of an absorbance in a wavelength range of 400 nm or longer and shorter than 580 nm to a minimum value B of an absorbance in a wavelength range of 580 nm to 770 nm is 0.3 to 3, and a ratio C/D of a minimum value C of an absorbance in a wavelength range of 400 nm to 750 nm to a maximum value D of an absorbance in a wavelength range of 850 nm to 1300 nm is 5 or higher.
