Abstract
A photocurable inkjet printing ink composition contains a photopolymerizable compound and a photopolymerization initiator, wherein in 100 percent by mass of the photocurable inkjet printing ink composition, included are: an acrylamide-based monomer by 5.0 to 50 percent by mass; a monofunctional monomer other than acrylamide-based monomer by 15 to 70 percent by mass; a polymerizable compound having two or more functionalities by 5.0 to 30.0 percent by mass; vinyl caprolactam by 0.1 to 15 percent by mass and/or an acrylated amine compound having two photopolymerizable functional groups and two amino groups in the molecule by 0 to 10 percent by mass; and the percentage of monofunctional monomers in the photopolymerizable compound is 60 to 99.5 percent by mass.
