Abstract

Provided is a photocurable ink composition for inkjet printing which is favorably cured with light from a light-emitting diode (LED), favorably adheres to a polyvinyl chloride sheet such as a tarpaulin and a vinyl chloride resin sheet, suppresses the occurrence of cockling, and has both safety and favorable ejection stability at room temperature when ejected from an inkjet head for low-viscosity ink, and a printed material. The present invention is a photocurable ink composition for inkjet printing containing photopolymerizable compounds and a photopolymerization initiator. The photopolymerizable compounds are vinyloxyethoxyethyl acrylate and benzyl acrylate, and contained in specific amounts. The photopolymerization initiator is a compound that expresses an initiator function when irradiated with light having a wavelength within the range of 450 to 300 nm. The photocurable ink composition has a flash point of 70° C. or higher and a viscosity at 25° C. of 5 mPa·s or lower, and further contains 50% by mass or more of a monofunctional monomer.
