Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pigment ink for inkjet recording excellent in printability, discharge stability from an inkjet nozzle and preservation stability.SOLUTION: The pigment ink for inkjet includes a pigment, a water-soluble solvent, water and a pigment dispersion resin, wherein the pigment dispersion resin is a copolymer comprising at least an ethylenically unsaturated monomer (a1) having a quaternary ammonium base. The pigment ink for inkjet is a copolymer containing the following monomer X in the copolymer composition. Monomer X: an ethylenically unsaturated monomer (a2) having an alkyl group having 6 or more carbon atoms.
