Abstract: PROBLEM TO BE SOLVED: To provide a high-quality multicolor image of which the colored inks exhibit almost the same discoloration ΔE after long-time storage, the color balance after long-time storage is destroyed little, and the bleed between a pigment-containing black ink and a color ink is moderated. SOLUTION: An ink set is provided which comprises a black ink containing an aqueous medium and a pigment dispersed therein by the action of an ionic group and at least two color inks each containing a colorant and an aqueous medium. Each of the color inks gives such as image that its light discoloration, expressed by ΔE in a CIELAB color space display system, differs from that of images given by other color inks by 10 or lower. The ΔE is obtained by a light resistance test under such conditions as to cause the discoloration equivalent to that caused by sunlight exposure through a window in a pseudoroom for at least 3 years. At least one color ink contains at least either a colorant or an additive unstabilizing the dispersion of the pigment in the black ink.
