Abstract
A photocurable ink composition for inkjet printing is obtained that has superior curability with respect to light from a light-emitting diode, has favorable adhesion to a polyvinyl chloride-based sheet, and is able to adequately inhibit the occurrence of cockling. The photocurable ink composition for inkjet printing at least has: a photopolymerizable compound; a photopolymerization initiator; and a sensitizer, wherein benzyl acrylate, N-vinylcaprolactam and an acrylated amine compound having two photopolymerizable functional groups and two amino groups in a molecule thereof are contained as the photopolymerizable compound, the content of the benzyl acrylate is 20 to 65% by mass in the photocurable ink composition for inkjet printing, a compound exhibiting an initiator function when irradiated with light having a wavelength of 450 to 300 nm is contained as the photopolymerization initiator, a compound exhibiting a sensitizer function when irradiated with light having a wavelength of 400 nm or longer is contained as the sensitizer, and a flash point as measured using a SETA closed-cup flash point tester according to a method in compliance with JIS K2265 is 70° C. or higher.
