摘要:
A method for producing a reduced-moisture-content-solvent ink composition includes reducing the moisture content of a pigment dispersion containing a metal pigment and a dispersion medium or an ink composition containing the pigment dispersion and an organic solvent by bubbling treatment using an inert gas having a water vapor content of 2.0 mg/L or less.
