Pigment dispersion liquid containing organic color pigment and infrared absorbing dye, colored resin composition, and optical filter

A color filter comprising a colored resin composition, the colored resin composition comprising:

• one or more organic color pigments selected from the group consisting of pigment red, pigment green, pigment blue, pigment yellow, and pigment violet;
• an infrared absorbing dye having a maximum absorption wavelength in a wavelength region of 750 to 2000 nm;
• an oil-soluble organic solvent or an aqueous medium;
• and
• a photopolymerizable monomer;
• wherein the infrared absorbing dye is a compound represented by the following formula (1):
• wherein
• R1 to R24 each independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, a substituted or unsubstituted heterocyclic group having 4 to 20 carbon atoms, —OR25 or —SR26;
• R25 and R26 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 20 carbon atoms;
• and M represents two hydrogen atoms, a metal atom, a metal oxide, or a metal halide;
• and
• wherein the color filter is:
• a red color filter showing a spectral transmittance determined with an ultraviolet-visible spectrophotometer after heating at 230° C. for 60 minutes of being 20% or less at 400 nm, being 15% or less at 530 nm, being 85% or more at 610 nm, and being 60% or less at 910 nm;
• a blue color filter showing a spectral transmittance determined with an ultraviolet-visible spectrophotometer after heating at 230° C. for 60 minutes of being 70% or more at 450 nm, being 15% or less at 700 nm, falling within the range of 510 nm ±5 nm for 50% spectral transmittance wavelength, and being 80% or less at 910 nm;
• or
• a green color filter showing a spectral transmittance determined with an ultraviolet-visible spectrophotometer after heating at 230° C. for 60 minutes of being 10% or less at 450 nm, being 70% or more at 550 nm, being 25% or less at 650 nm, and being 80% or less at 910 nm.
