摘要： In the present invention, an inkjet recording ink can be provided, which ink can record stably an image with good fastness and elegant-quality over a long period in any conditions. The ink comprises a high-molecular dispersant, a water-insoluble colorant, water-soluble organic solvent and water, in which the high-molecular dispersant is a block copolymer comprising at least one hydrophobic block and at least one hydrophilic block, which have been obtained by polymerizing vinyl ethers as monomers, respectively; and the water-insoluble colorant is a specific pigment. Further the present invention can provide a inkjet recording method, an inkjet cartridge, and an inkjet recording system.

摘要： An inkjet recording ink is composed of a high-molecular dispersant, a water-insoluble colorant, a water-soluble organic solvent, and water. The water-insoluble colorant is at least one colorant selected from the group consisting of C.I. Solvent Yellow 21, 42, 79, 82, 83:1, 88 and 151, at least one colorant selected from the group consisting of C.I. Solvent Red 8, 49, 83:1, 91, 127 and 218, at least one colorant selected from the group consisting of C.I. Solvent Black 3, 27, 29 and 45, or at least one colorant selected from the group consisting of C.I. Solvent Blue 25, 38, 44, 67 and 70. The high-molecular dispersant is a block copolymer comprising at least one hydrophobic block and at least one hydrophilic block, which have been obtained by polymerizing vinyl ethers as monomers, respectively. The inkjet recording ink can stably record images of high fastness and excellent quality over a long period even under severe environmental conditions.
