Ink set for ink jet recording and method for ink jet recording
Disclosed is a five-color ink set for ink jet recording, which can realize good images excellent in lightfastness and waterfastness, as well as particularly in hue. The five-color ink set for ink jet recording comprises a cyan ink composition, a magenta ink composition, a yellow ink composition, a green ink composition and an orange ink composition, wherein the cyan ink composition comprises C.I. Pigment Blue 15:3 or C.I. Pigment Blue 15:4, the magenta ink composition comprises C.I. Pigment Red 122, C.I. Pigment Red 202, C.I. Pigment Red 209 or C.I. Pigment Violet 19, the yellow ink composition comprises C.I. Pigment Yellow 213, the green ink composition comprises C.I. Pigment Green 7 or C.I. Pigment Green 36, and the orange ink composition comprises C.I. Pigment Orange 64, C.I. Pigment Orange 43 or C.I. Pigment Orange 71.
