Inkjet-recording ink composition and image-forming process

摘要

A photopolymerization-curable inkjet-recording ink composition, comprising 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 2.6x10^-13 [m³(STP).m/(s.m².kPa)] or lower.
