<P>PROBLEM TO BE SOLVED: To provide an aqueous inkjet ink which is excellent in printability to a general printing base material, particularly, a high hydrophobic base material such as coated paper, art paper or vinyl chloride sheet, and also excellent in discharge stability from an inkjet nozzle, storage stability and weatherability. <P>SOLUTION: The inkjet pigment ink contains at least pigment yellow 150, a water-soluble solvent, water and a pigment dispersion resin. The pigment dispersion resin is a copolymer including the following monomers A, B, C in the copolymerization composition: the monomer A is a (meth)acrylate ester having 18-24C alkyl; the monomer B is styrene, α-methylstyrene or benzyl (meth)acrylate; and the monomer C is a (meth)acrylic acid. The water-soluble solvent is at least one selected from glycol ethers and diols. <P>COPYRIGHT: (C)2013,JPO&INPIT |
