Abstract
A photocurable inkjet printing ink composition contains a pigment, a pigment dispersant, a photopolymerization initiator, and a photopolymerizable compound, wherein the photopolymerizable compound contains a hydrophilic monofunctional monomer and a phosphate (meth)acrylate; the phosphate (meth)acrylate is included in an amount of 0.2 to 4.0 mass % based on the entire ink composition; a mass ratio of the hydrophilic monofunctional monomer to the phosphate (meth)acrylate is 15 to 300; and the pigment dispersant is included in an amount of 38 to 90 parts by mass based on 100 parts by mass of the pigment.
