<p><P>PROBLEM TO BE SOLVED: To provide active energy ray-curable ink that is curable by an active energy ray and designed to be cured by a wavelength of ultraviolet ray irradiated by a light emitting diode, and has excellent curability to ultraviolet ray irradiated by the light emitting diode which emits specific ultraviolet ray, and also has excellent storage stability. <P>SOLUTION: The active energy ray-curable ink including a compound (C) having an ethylenic double bond contains a thioxanthone compound (A) and anα-aminoalkyl phenone-based photoinitiator (B) as a photoinitiator, and further includes a tertiary amine compound (D). The level of the thioxanthone compound (A) is a specific amount when multi-color printing using a multi-color set of the active energy ray-curable ink including the compound having the ethylenic double bond. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
