ABSTRACT:
An active energy ray-curable ink composition comprising a colorant, a monomer and a photopolymerization initiator, in which the monomer contains an acrylamide derivative in an amount of 10 to 90% by weight based on the whole weight of the ink composition, and the ink composition has a viscosity of 3 to 35 mPa·s at 25° C. The ink composition has a low viscosity without dilution by a diluent solvent, good storage stability, good pigment dispersibility when a pigment is used as a colorant and also good continuous ejection stability to a printing medium, has a good curing property at a low energy level such as a cumulative amount of light of 150 mJ/cm2or less, and it can attain good printing quality on nonabsorbable printing medium and achieves good adhesion of printed images to the printing medium.
