Abstract
A problem of the present invention is to provide an ink set and an ink jet recording method, according to which a high-quality printed article can be provided for which deformation such as wrinkling does not occur, the color density is high, and there is little blotting or unevenness even if regular paper is used as the recording medium. An ink set of the present invention comprises at least inks of three colors, that is a yellow ink having a hue angle ∠H° as defined in CIELAB color space on a recording medium in a range of approximately 80° to approximately 110°, a magenta ink having the above-mentioned hue angle ∠H° in a range of approximately 330° to approximately 360°, and a cyan ink having the above-mentioned hue angle ∠H° in a range of approximately 230° to approximately 260°; an ink (A) having the above-mentioned hue angle ∠H° in a range of approximately 0° to approximately 80° and/or an ink (B) having the above-mentioned hue angle ∠H° in a range of approximately 260° to approximately 330°; and a reaction liquid containing a reactant. [∠H°=tan (b*/a*)+180° in the case that a*<0, and ∠H°=tan (b*/a*)+360° in the case that a*>0].
