Abstract:
An ink jet ink composition set includes a white ink jet ink composition and a nonwhite ink jet ink composition. The white ink jet ink composition contains a white pigment, resin particles, and water, and the nonwhite ink jet ink composition contains a nonwhite pigment, resin particles, and water. The white pigment has cation responsiveness, and the absolute value of zeta potential of the white pigment is lower than the absolute value of zeta potential of the nonwhite pigment.
