Abstract

Abstract A water-based ink set for ink-jet recording includes at least a yellow ink, a magenta ink and a cyan ink. At least one color ink of the yellow, magenta and cyan inks includes a first ink and a second ink which have different hue angles h having therebetween the color range of the normal color of the color ink. Preferably, the yellow ink includes a greenish yellow ink having a hue angle h of about 95° to about 110° and a reddish yellow ink having a hue angle h of about 70° to about 85°; the magenta ink includes a reddish magenta ink having a hue angle h of about 0° to about 10° and a violetish magenta ink having a hue angle h of about 340° to about 350°; and the cyan ink includes a bluish cyan ink having a hue angle h of about 250° to about 260° and a greenish cyan ink having a hue angle h of about 230° to about 240°.
