摘要： The present disclosure relates to an ink-jet ink set which, in spite of using a black ink including a black pigment, may form printed matter (e.g., images) with desirable water resistance and/or color balance after fading (fading stability) and/or ink-jet ink sets with desirable storage stability. An ink set may include a yellow dye ink including a yellow dye, a magenta dye ink including a magenta dye, a cyan dye ink including a cyan dye and a black ink. A black ink may include a black pigment, a yellow dye, a magenta dye and a cyan dye. A black ink may have a weight ratio of an amount of a black pigment to a total amount of the yellow dye, the magenta dye, and the cyan dye of from about 5/95 to less than about 30/70 (e.g., from about 5/95 to about 30 (but not inclusive of 30)/70).

摘要： A water based ink set for ink-jet recording includes a yellow ink, a magenta ink, a cyan ink, a black ink, and a red ink and/or a blue ink each including at least a coloring agent, water and a water soluble organic solvent. In the water based ink set, a water soluble dye is employed as the coloring agent of each of the yellow ink, the magenta ink and the cyan ink, and a pigment is employed as the coloring agent of each of the black ink and the red ink and/or the blue ink. In an ink-jet recording method employing the water based ink set for ink-jet recording, the red ink and the magenta ink are employed together for a magenta-ink-recording portion, and the blue ink and the cyan ink are employed together for a cyan-ink-recording portion.

摘要： A water base ink for ink-jet recording contains self-dispersible carbon black as a coloring agent. The total content of an organic acid having a number of carbon or carbons of 1 to 6 and a salt of the organic acid is not more than 400 ppm. The organic acid having a number of carbon or carbons of 1 to 6 includes monocarboxylic acid, dicarboxylic acid and oxy acid, and the salt of the organic acid includes salts of these acids. When the water base ink is used in an ink-jet recording apparatus, the discharge stability of the ink is improved.
