<P>PROBLEM TO BE SOLVED: To provide an ink stock solution for inkjet recording having excellent ejection stability and especially suitable for an electrostatic inkjet recording of concentrated coloring material ejection type, a method for producing the stock solution and ink for inkjet recording. <P>SOLUTION: The ink stock solution for inkjet recording at least contains a dispersion medium, coloring material particles containing a resin and a dispersing agent and the solution exhibits Newtonian fluidity. The ink stock solution is obtained by swelling or softening the coloring material particles containing the resin during and/or after the dispersing process. The ink for inkjet recording is produced by diluting the ink stock solution with a dispersion medium to attain a viscosity of 0.5-5 mPa×s at 20°C. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
