PROBLEM TO BE SOLVED: To provide an inkjet pigment ink as a pigment ink for inkjet recording, which shows excellent permeability to a general printing base material, particularly a base material having high hydrophobicity such as a coated paper, art paper and a vinyl chloride sheet, and thereby, which has excellent printing property, excellent discharge stability from an inkjet nozzle, and excellent storage stability of the ink.SOLUTION: The inkjet pigment ink comprises a pigment, a water-soluble solvent, water, and a pigment dispersing resin. The pigment dispersing resin is a copolymer having a copolymer composition containing an ethylenically unsaturated monomer having a fluorine atom and an ethylenically unsaturated monomer having an alkyl group having 10 or more and 24 or less carbon atoms.SELECTED DRAWING: None |
