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.

Abstract: A resin composition including a resin R including a repeating unit having a partial structure of Formula (I) or (II): where QA is an ester bond shown in the Formula (I), RA is a substituent group, n1 is any of integers 1 to 5, * is a bonding site with a remainder of the repeating unit, and ** is a bonding site with a phenyl group in the Formula (I); where QB is a linking group or a single bond other than the ester bond of QA in Formula (I), RB is a substituent group, with at least one RB being a hydroxyl group, n2 is any of integers 1 to 5, and * is a bonding site with a remainder of the repeating unit.

Abstract: An infrared cut-off filter, including a cyanine dye and a copolymer. The cyanine dye includes tris(pentafluoroethyl) trifluorophosphate and a cation having a polymethine and a nitrogen-containing heterocycle at each end of the polymethine. The copolymer includes a first repeating unit from a first monomer and a second repeating unit from a second monomer different from the first monomer. The first monomer includes a phenolic hydroxyl group.

Abstract: An infrared cut filter including a film that includes a cyanine dye including a cation having a polymethine and a nitrogen-containing heterocycle at each end of the polymethine, and a tris(pentafluoroethyl)trifluorophosphate anion, and a copolymer including a first repeating unit from a first monomer that is an acrylic monomer having a cyclic ether group, and a second repeating unit from a second monomer that is a monomer having a functional group that reacts with the cyclic ether group.
