PROBLEM TO BE SOLVED: To provide an energy ray-curable inkjet ink composition excellent in storage stability.SOLUTION: The energy ray-curable inkjet ink composition includes at least a quinacridone-based pigment, a high-molecular compound, and an organic solvent, wherein the total concentration of the monovalent cation in the water phase is 200 ppm or less when the ions in the energy ray-curable inkjet ink composition are phase-inverted to pure water. The energy ray-curable inkjet ink composition generates a small amount of precipitates after long-term storage and has excellent storage stability. |
