Abstract:
A composition for forming a colored layer includes a dye, an ionizing radiation-curable resin, a photoinitiator, and a solvent. The dye contains a first colorant and a second colorant, the first colorant has a wavelength of maximum absorption in a range of 470 nm to 530 nm, and an absorption spectrum with a full width at half maximum of 15 nm to 45 nm, the second colorant has a wavelength of maximum absorption in a range of 560 nm to 620 nm, and an absorption spectrum with a full width at half maximum of 15 nm to 55 nm, and the ionizing radiation-curable resin contains a resin having an amine structure.
