PROBLEM TO BE SOLVED: To provide ink that can record an image having excellent scratch resistance and color development.SOLUTION: There is provided inkjet ink containing a pigment, a resin particle, and an urethane resin. In the ink, the resin particle is formed of a copolymer having a unit (X) derived from α-olefin polymer, a unit (A) derived from α,&bgr;-ethylenic unsaturated acid monomer comprising maleic acid, and a unit (B) derived from α,&bgr;-ethylenic unsaturated monomer other than the α,&bgr;-ethylenic unsaturated acid monomer, the density of the α-olefin polymer is 850 kg/mor more and 960 kg/mor less, and the urethane resin comprises a poly(oxytetramethylene) structure. |
