<P>PROBLEM TO BE SOLVED: To provide an inkjet-printing ink set by using a dispersion dyestuff excellent in preserving property and a method for inkjet-recording. <P>SOLUTION: This inkjet-printing ink set using in a plurality of the inkjet inks each contains at least a dispersion dyestuff, a dispersing agent, water and a water-soluble organic solvent, provided that a value obtained by dividing the containing rate of the water-soluble organic solvent having ≤40 dielectric constant used for the dispersion dyestuff showing the minimum log P value among the main dispersion dyestuffs in the inks by the containing rate of the water-soluble organic solvent having ≤40 dielectric constant used for the dispersion dyestuff showing the maximum log P value among the main dispersion dyestuffs in the inks is ≤1. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
