    摘要： A set of color ink compositions for ink-jet printing includes yellow, magenta and cyan ink composition, each of which having water, a water-soluble coloring agent, a wetting agent, a surfactant and an antiseptic and mildewproofing agent, and the yellow ink composition has the lightness index L* of 95.+-.5 and the chromaticness indices a* and b* of respectively -6.+-.5 and 23 .+-.12, the magenta ink composition has the lightness index L* of 75.+-.5 and the chromaticness indices a* and b* of respectively 55.+-.25 and -28.+-.10, and the cyan ink composition has the lightness index L* of 87.+-.5 and the chromaticness indices a* and b* of respectively -35.+-.10 and -19.+-.8. Further, color ink images are formed on a recording material with a Stockigt sizing degree of 10 sec or more using the above set of color ink compositions and a printing head with a plurality of ink-ejecting orifices by performing dot printing on the recording material by ejecting the ink compositions from the ink-ejecting orifices with the printing head scanned over the recording material a plurality of times.
