摘要：
A pigment dispersion liquid is a pigment dispersion liquid for a solvent-based ink including a base metal pigment and an organic solvent, in which the base metal pigment is subjected to a surface treatment by a fluorine-based compound, and in which the concentration of a fluorine element is from 8 atm % to 35 atm % when an X-ray photoelectron spectroscopy (XPS) analysis of the surface of the base metal pigment is performed.
