<P>PROBLEM TO BE SOLVED: To provide an inkjet ink capable of suppressing the generation of curling of a medium to be recorded when the ink is imparted after realizing the good discharge stability of the ink, moreover having excellent dispersion stability of the ink and after-thermo droplet landing position accuracy and capable of preventing the generation of image deformation and to provide an ink set and method for forming image using the ink. <P>SOLUTION: In the inkjet ink containing at least (a) water-soluble organic solvent, (b) water, (c) pigment and (d) polymer dispersant, ≥70 mass% of the water-soluble organic solvent is composed of water-soluble solvent having a solubility parameter (SP value) of ≤27.5, and a free component in the polymer dispersant is ≤1.0 mass%. <P>COPYRIGHT: (C)2011,JPO&INPIT |
