[PROBLEMS] To provide excellent storage stability, excellent curability by ultraviolet rays using a light-emitting diode (LED) as a light source, excellent gloss of printed matter, stretchability, and when folded printed paper or film. Provided is an active energy ray-curable ink composition for ink jet printing which can follow a print portion and prevent cracks from being generated in the print and is excellent in tackiness. An active energy ray-curable ink composition for ink jet printing, comprising at least a photopolymerizable compound, a photopolymerization initiator, and an organic solvent, comprising a monofunctional photopolymerizable compound, a polyfunctional Contains a photopolymerizable compound, contains a monomer and / or oligomer having a glass transition temperature of −30 ° C. or lower, and a monomer and / or oligomer having a glass transition temperature of 80 ° C. or higher, and has an amino group and / or an amide group. An active energy ray-curable ink composition for inkjet printing, which contains a monomer and / or oligomer and has a viscosity of 10 mPa · s or less at 25 ° C. [Selection] Figure 1 |
