ABSTRACT:
An object of the present invention is to provide an ink jet ink capable of suppressing bronzing phenomenon in which a reflected light of an image looks red, is excellent in color developability, and gives an image with suppressed bleeding even when formed adjacent to an image formed with a black ink. The ink jet ink comprises water, coloring materials, and a water-soluble organic solvent, in which the coloring materials comprise at least one dye selected from the group consisting of C.I. Direct Blue 199, C.I. Direct Blue 86, and C.I. Acid Blue 9, and a pigment having a copper phthalocyanine skeleton; the water-soluble organic solvent comprises a poor medium for the pigment having the copper phthalocyanine skeleton; and a content of the pigment having the copper phthalocyanine skeleton in the ink is less than 1 mass % with respect to a total mass of the ink jet ink.
