ABSTRACT:
The present invention provides a black water-based ink composition that has excellent resistance to light and ozone, has an excellent hue as a black ink, and also has excellent storage stability. A black water-based ink composition is prepared by combining at least one type of black dye selected from the group consisting of compounds expressed by the following formula (1) and salts thereof:and at least one type of dye other than a black dye, and the hue is adjusted by adding the dye other than a black dye. It is preferable if the dye other than the black dye is a compound that has at least one type of group selected from the group consisting of an —SO3H group, —COOH group, —SO3M group, and —COOM group (where M in these groups is an alkali metal atom), and is not an ammonium salt or a salt with an organic cation. It is also preferable for the dye other than the black dye to be a dye selected from the group consisting of yellow dyes and magenta dyes.
