    摘要： A method for preparing a pigment dispersion including subjecting a mixture including at least a pigment, a dispersant and water to a first dispersion treatment using a media mill to prepare a first dispersion; and then subjecting the first dispersion to a second dispersion treatment using a media-less mill to prepare the pigment dispersion, wherein the pigment in the pigment dispersion has an average particle diameter (D50) of from 20 to 130 nm for pigments except carbon black or from 70 to 180 for carbon black, and the standard deviation of the particle diameter of the pigment is less than the average particle diameter (D50) for pigments except carbon black or one half of the average particle diameter (D50) for carbon black. A pigment dispersion prepared by the method. An inkjet ink including the pigment dispersion and one member selected from water, water soluble organic solvents, and surfactants.

    摘要： The present invention provides an inkjet ink containing at least a colorant, water, a water insoluble resin, a fluorine surfactant, and a polyether-modified silicone oil, wherein the polyether-modified silicone oil has a hydrophobic value of 0.40 to 1.5, and the hydrophobic value is expressed by Equation 1: Hydrophobic value=A/B  Equation 1 where “A” represents an integration value of a peak area from 0 ppm to 0.3 ppm in a 1H-NMR spectrum of the polyether-modified silicone oil using tetramethylsilane as a reference substance; and “B” represents an integration value of a peak area from 3.5 ppm to 4.0 ppm in the 1H-NMR spectrum.
