The purpose of the present invention is to provide an inkjet ink which has excellent curing sensitivity, weather resistance in the form of a cured film, solvent resistance and viscosity stability when stored for a long period, and does not cause printed materials to curl due to the curing shrinkage of the ink, said inkjet ink using a CT polymerization system and having excellent flexibility when the ink is printed. This active energy-ray curable inkjet ink contains at least one type of acceptor monomer and at least one type of donor monomer. The acceptor monomers include a polyfunctional acceptor monomer, the donor monomers include a monofunctional donor monomer, and the ratio (X) (the ratio of the double bonded functional group mol number of the acceptor monomer and the mol number of the donor monomer, per mass unit) is 0.66-2. |
