<P>PROBLEM TO BE SOLVED: To provide inkjet ink which allows an image printed therewith on a non-absorbent recording medium to have high abrasion resistance, high adhesion properties, high gloss and high quality and allows an inkjet head to have high jetting property and excellent recoverability after maintenance and to provide an inkjet recording method using the inkjet ink. <P>SOLUTION: The water-based inkjet ink contains, at least, water, a pigment, a resin, a water-soluble organic solvent and a silicone-based or fluorine-based surfactant. The resin contains a copolymer resin synthesized from a monomer containing, at least, methyl methacrylate, an acid monomer, alkyl acrylate having a 2-4C alkyl group and alkyl acrylate having a 6-12C alkyl group. The copolymer resin has 50-120 mg-KOH/g acid value, 30-110°C glass transition temperature (Tg) and 20,000-80,000 weight-average molecular weight (Mw). <P>COPYRIGHT: (C)2011,JPO&INPIT |
