PROBLEM TO BE SOLVED: To provide an active ray curable composition which poses no problem of corrosion, denaturation and the like due to reaction active species, and can reduce remaining monomers (polymerizable compounds) because the reaction and curing progress even after the light irradiation; and to provide an active ray curable inkjet ink which is good in quality for a recording medium, and can be printed at a high speed.SOLUTION: An active ray curable inkjet ink is made by using an active ray curable composition containing a photobase generating agent generating a base by active ray irradiation and represented by formula (I), and a polymerizable compound reacting with the base generated by the active ray irradiation. In the formula, Rand Rare each independently a hydrogen atom, an alkyl group which may have a substituent or a group composed of an alicyclic structure, or Rand Rbond to form a heterocyclic structure which may have a substituent; and Ris a hydrogen atom or a methyl group. |
