Abstract
An ink-jet ink which comprises a dye dispersed product, an oil-soluble dye being dissolved in a high boiling point organic solvent which has a boiling point of 150° C. or more and has a specific inductive capacity at 25° C. of 3 to 12, the oil-soluble dye is emulsified and dispersed in a water-based medium, and the dye dispersed product is formed. Further, a method of manufacturing an ink-jet ink, in which an oil-soluble dye is dissolved in a high boiling point organic solvent which has a boiling point of 150° C. or more and has a specific inductive capacity at 25° C. of 3 to 12, and the oil soluble dye is emulsified and dispersed at a pressure of 50 MPa or more using a high-pressure emulsifying and dispersing device.
