Abstract:
Provided is an inkjet ink which can form high-quality images with high abrasion resistance and adhesiveness on a non-absorptive recording medium and which exhibits high ejection properties and excellent storage stability. Also provided is an inkjet recording method. An inkjet ink which comprises water, a pigment, a water-soluble resin, a water-soluble or Panic solvent and a surfactant, characterized in that: the water-soluble resin comprises a water-soluble resin consisting of a copolymer resin which has an acid value of 50 to 130 mgKOH/g, a glass transition temperature (Tg) of 30 to 100° C., and a weight-average molecular weight (Mw) of 20,000 to 80,000, said copolymer resin being a resin which is synthesized from a monomer component that comprises methyl methacrylate, an alkyl acrylate or methacrylate, and an acid monomer and in which the total mass of methyl methacrylate and the alkyl acrylate or methacrylate is 80 to 95% relative to the total mass of all of the monomers constituting the copolymer resin; and the surfactant comprises a fluorochemical surfactant and a polyoxyethylene alkyl ether.
