Abstract

An ink composition containing at least two kinds of water-soluble long-wavelength dyes whose absorption spectrum in an aqueous solvent has a maximum wavelength of 550 nm to 700 nm, in which at least one kind of the water-soluble long-wavelength dyes is a first water-soluble long-wavelength dye of an azo compound represented by the following Formula (1), at least one kind of the water-soluble long-wavelength dyes is a second water-soluble long-wavelength dye that is different from the first water-soluble long-wavelength dye, and the second water-soluble long-wavelength dye is a compound having two to four azo groups conjugated with each other per molecule, an ink for inkjet recording using the ink composition, and an inkjet recording method using the ink for inkjet recording using the ink for inkjet recording.
