<P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a pigment dispersion with sufficient dispersion stability and a water-based ink for inkjet recording being excellent in delivery stability. <P>SOLUTION: The pigment dispersion is manufactured by the manufacturing method including a step of obtaining a water-based dispersion by mixing a water-insoluble resin, carbon black, a neutralizing agent, an organic solvent, a non-ionic surfactant and a water-based medium and a step of removing at least a part of the organic solvent from the water-based dispersion. Further, the water-based ink for inkjet recording contains the pigment dispersion manufactured by the manufacturing method. <P>COPYRIGHT: (C)2010,JPO&INPIT |
