<P>PROBLEM TO BE SOLVED: To obtain an ink composition for inkjet-recording, always capable of ejecting ink droplets stably through a long time of the inkjet-recording and enabling the formation of a high quality image for a long time, and to provide a method for inkjet-recording. <P>SOLUTION: The ink composition for the inkjet-recording satisfies the following conditions (A) to (D) in the ink composition containing charged particles containing at least a dispersion medium and a coloring agent. (A) The electric conductivity of the ink composition at 20°C is within a range of 10-300 nS/m. (B) The electric conductivity of the charged particles is ≥50 % of the electric conductivity of the ink composition. (C) The volume average-diameter of the charged particles is within a range of 0.2-5.0 μm, and. (D) The viscosity of the ink composition at 20°C is within a range of 0.5-5 mPa s. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
