INKJET RECORDING INK SET, INK CARTRIDGE, INKJET RECORDING DEVICE, INKJET RECORDING METHOD, AND IMAGE FORMED MATTER
摘要:
To provide an inkjet recording ink set, which contains a cyan ink, magenta ink, yellow ink, and black ink, wherein each ink contains at least a pigment, a surfactant, water, water-soluble organic solvent, and anionic self-emulsifying ether-based polyurethane, wherein each ink contains, as the pigment, a combination of a (i) pigment dispersion liquid, in which the pigment is dispersed in water with assistance of the surfactant, and a (ii) resinous polymer-coated pigment dispersion liquid, in which the pigment is coated with a resinous polymer and dispersed in water, and wherein the (i) pigment dispersion liquid and the (ii) resinous polymer-coated pigment dispersion liquid satisfy the following formula: |A−B|≦30 nm where A is the average particle diameter (D50) of the dispersed pigment in the (i) pigment dispersion liquid, and B is the average particle diameter (D50) of the dispersed resinous polymer-coated pigment in the (ii) pigment dispersion liquid.
