A photopolymerization-curable inkjet-recording ink composition, including an ethylenic unsaturated monomer, a colorant, and a photopolymerization initiator containing an organic dye and an organic boron compound. The ethylenic unsaturated monomer is preferably a compound which polymerizes to form a polymer having an oxygen permeability coefficient at 25° C. of 2.6×10 −13 [m 3 (STP)·m/(s·m 2 ·kPa)] or lower. |
