Abstract: An ink set for recording a color image with inks of two or more colors comprising at least one black ink and one color ink on a recording medium is provided. The ink set comprises a black ink containing a self-dispersible carbon black having at least one cationic group bonded directly or through another atomic group to the surface thereof, and a color ink containing an anionic substance and having a buffering capability against a pH change. The ink set satisfies the requirements for print quality, image durability, and so forth and does not cause bleeding between a black ink-printed area and a color ink-printed area.

Abstract: An ink set includes inks each containing a colorant and an aqueous medium, wherein in a fading test under conditions that cause fading corresponding to pseudo-indoor sunlight fading through a window for 3 years or more, the difference between respective images' ”E, the images being produced with the respective inks, is 10 or less in a CIELAB color space display system, and each of the images has a residual ratio of reflection density of 70% or more. By using the ink set including the color inks with which images having substantially the same fading ”E after long-term storage are produced, the color balance of a recorded image can be maintained after long-term storage.
