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.
