<p>An energy ray-curable inkjet ink composition comprising polymerizable compounds containing a monofunctional monomer, (A) a reactive oligomer having a rate of elongation of 130 % or more and a weight average molecular weight of not less than 800 and less than 3,000 and (B) a reactive oligomer having a rate of elongation of 130 % or more and a weight average molecular weight of not less than 3,000 and not more than 8,000, provided that one of the reactive oligomers (A) and (B) is not more than difunctional and the other is not less than difunctional, at least one polymerization initiator selected from the group consisting of (C) an acylphosphine oxide initiator and (D) an ±-aminoalkylphenone initiator, a surface tension modifier, and a colorant.</p> |
