Abstract:
Disclosed is an inkjet ink which provides a high-quality image in that whitening of the recorded image film is inhibited, durability of the image is good, and there is no banding, and the like; inkjet injection stability and ink shelf life are excellent; and head maintenance returnability is excellent. Also disclosed are a method for producing an inkjet printed product using the same, and a method for producing a water-based inkjet ink. This inkjet ink comprises at least a) a pigment, b) a polymer dispersant comprising polyethylene oxide groups having an acid value of less than 50 mgKOH/g (c) acrylic copolymer resin, and (d) at least one water-soluble organic solvent selected from glycol ethers and 1,2-alkanediols having 4 or more carbons.
