ABSTRACT:
The present invention provides an ink set comprising at least three color inks, which are yellow ink whose hue angle H°, as defined in the CIELAB color space on a recording medium (PM photographic paper; same below), is in a range of about 80° to about 110°, magenta ink whose hue angle H° is in a range of about 330° to about 360°, and cyan ink whose hue angle H° is in a range of about 230° to about 260°, and further comprising ink (A) and/or ink (B) described below. With the present ink set, it is possible to provide a highly reliable ink set that can be used in inkjet recording and can produce printed matter having a wide color reproduction range, high color saturation, good graininess, and an adequate glossy look.
