PROBLEM TO BE SOLVED: To provide a water-based ink which has excellent dischargeability, suppresses reduction in an ink dot diameter during drying process even when printed on a low water absorption recording medium, and can provide an image having excellent uniformity, and to provide an inkjet recording method using the water-based ink.SOLUTION: Provided are [1] a water-based ink comprising pigment, a water-insoluble polymer, an acetylene glycol-based nonionic surfactant (A) having an HLB of 0 to 5, a nonionic surfactant (B) having an HLB of 6 to 20, a polyether-modified silicone (C) having a kinematic viscosity of 30 to 190 mm/s at 25°C, and an organic solvent (D), in which a weighted average value of boiling point of the organic solvent (D) is 150 to 230°C, and [2] an inkjet recording method recording in a recording medium using the water-based ink, in which an amount of water absorbed by the recording medium in a contact time of the recording medium and pure water of 100 milliseconds is 0 to 10 g/m.SELECTED DRAWING: None |
