<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable ink which has curability by an active energy ray, is especially designed considering ultraviolet irradiated by a light-emitting diode which generates ultraviolet having 350-420 nm of an emission peak wavelength range as a curing wavelength, has outstanding curability to ultraviolet irradiated by a light-emitting diode which generates ultraviolet having 350-420 nm of an emission peak wavelength range, and further is excellent also in storage stability. <P>SOLUTION: The active energy ray-curable ink includes: a compound which has an ethylenic double bond; a photopolymerization initiator; and a tertiary amine compound, wherein the photopolymerization initiator is (A1) an α-aminoalkylphenone compound, (A2) an acylphosphine oxide compound and (B1) a thioxanthone compound. In addition, a printed matter printed by the active energy ray-curable ink is disclosed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
