<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable ink having curability by an active energy ray, which is especially designed so that an ultraviolet ray, irradiated by a light emitting diode generating an ultraviolet ray with an emission peak wavelength in the range of 350-420 nm, is used as a curing wavelength; which has excellent curability to the ultraviolet ray irradiated by the light emitting diode for generating the ultraviolet ray with the emission peak wavelength in the range of 350-420 nm; and which is excellent in storage stability. <P>SOLUTION: In the active energy ray-curable ink containing a compound having an ethylenic double bond and a photopolymerization initiator, the photopolymerization initiator is (A1) an α-aminoalkylphenone compound, (B1) a thioxanthone compound and (B2) a benzophenone compound. Printed matter printed by the active energy ray-curable ink is also provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
