Abstract
Disclosed herein is a base metal pigment, which is used for an aqueous ink composition containing water as a part of a solvent, in which the base metal pigment is surface-treated with a fluorine-based compound, and has a zeta potential of greater than or equal to −50 mV and less than or equal to −15 mV, as measured by an ultrasonic zeta potential measurement device, in a pH range of greater than or equal to 5 and less than or equal to 10.
