ABSTRACT:
There is provided a pigment dispersion comprising at least one resin-coated pigment comprising a resin and a pigment, and having an average particle diameter of 250 nm or less, and a dispersion medium containing as a major component a cation polymeric compound having a viscosity of 30 mPa.s or less at a temperature of 25° C. and a boiling point of 150° C. or more at 1 atm. The pigment is incorporated in the pigment dispersion at a ratio ranging from 3 to 41% by weight based on a total weight of the dispersion medium, and the resin is incorporated in the resin-coated pigment at a ratio ranging from 5 to 37% by weight based on the weight of the pigment.
