ABSTRACT:
An ink set for ink-jet recording is provided defined by an evaluation indicator approximately corresponding to an evaluation sensed by human eyes without relying on a color difference (ΔE) or an optical density difference (ΔOD) at the time of evaluating a long-term storage stability of the ink set for ink-jet recording. In the ink set for ink-jet recording which contains a yellow ink, a magenta ink and a cyan ink, values of hue angle change (Δh), between before and after lightfastness tests, of print regions corresponding to respective inks formed on glossy paper by using the yellow ink, the magenta ink and the cyan ink are not more than about 3° for the yellow ink, not more than about 2° for the magenta ink, and not more than about 6° for the cyan ink.
