Abstract
A dye composition includes: a water-insoluble dye; a specific dispersant for dispersing the water-insoluble dye; an alkylene oxide adduct of (poly)glycerin; and water, in which the specific dispersant contains a copolymer of a styrene compound and maleic acid, or a urethane resin, the alkylene oxide adduct of (poly)glycerin contains a propylene oxide group, a ratio (B/A) of a content B of the specific dispersant to a content A of the water-insoluble dye is 0.40 to 0.75, and a content of the alkylene oxide adduct of (poly)glycerin is 0.05 to 1.00 mass % with respect to a total amount of the dye composition.
