<P>PROBLEM TO BE SOLVED: To provide an ink set for inkjet recording which offers excellent image quality, reliability and fixability, an inkjet recording method using the same and an inkjet recording device. <P>SOLUTION: The ink set for inkjet recording has at least a black ink containing at least a pigment which is self-dispersible in water, a water-soluble organic solvent and water, and a color ink containing at least a pigment, a polymer dispersing agent, a water-soluble organic solvent and water. Here, (1) the black ink and the color ink each has surface tension of 25-39 mN/m, (2) the black ink and the color ink each has viscosity at 23°C of 2.0-10.0 mPa×s and (3) a mixed solution of the water-soluble organic solvent and water contained in the black ink has an average SP value by 0.01-1.5 smaller than that of a mixed solution of the water-soluble organic solvent and water contained in the color ink. The inkjet recording method and the inkjet recording device use the ink set. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
