摘要： An ink set which comprises a black ink containing an aqueous medium and a pigment dispersed in the aqueous medium by an action of an ionic group, and at least two color inks each containing a coloring material and an aqueous medium, wherein (i) respective images formed with the respective color inks have the same &Dgr;E or have the difference in &Dgr;E that is 10 or less in a CIELAB color space display system in a fading test under conditions that cause fading corresponding to pseudo-indoor sunlight fading through a window for 3 years or more, and (ii) at least one of the color inks contains at least one of a coloring material and an additive that destabilize dispersion stability of the pigment in the black ink. The ink set can provide a high quality multicolor image keeping color balance after long preservation and showing less bleeding between black and color regions.
