PROBLEM TO BE SOLVED: To provide an active energy ray-curable ink good in curing even under low energy irradiation conditions, also having low migration properties and having reduced odor.SOLUTION: Provided is an active energy ray-curable ink characterized in that, provided that an active energy ray-curable ink is applied to the surface of the ink receiving face 3 of a base material 1 provided with an ink receiving layer at 1.6×10g/cm, ultraviolet irradiation is performed under the conditions where laminated light quality reaches 10 mJ/cmso as to be a cured film 2, the cured film face 3 of the base material p1 free from odor from the cured film face 3 and provided with the cured film 2 cut to the area of 600 cmand the resin layer face of the base material p2 not provided with the cured film are superimposed, it is placed in a 95% ethanol aqueous solution of 1,000 ml under a load of 0.5 kg/cmunder the environment of 25°C and 50%RH for 48 hr. After that, when the base material p2 is immersed in an ethanol aqueous solution at 25°C in a 50% RH environment for 24 hr, and thereafter, when the whole concentration of a photopolymerization initiator present in the ethanol is measured, it is below 100 ppb.SELECTED DRAWING: Figure 1 |
