Abstract
An object is to obtain a photocurable inkjet printing ink composition demonstrating not only excellent LED curability and anti-yellowing property but also excellent solubility, while allowing its viscosity to be adjusted to an appropriate level even in the absence of solvent. As a solution, a photocurable inkjet printing ink composition is provided that contains 1.0 to 10.0% by mass of amine-modified oligomers relative to all photopolymerizable components, as well as 1.0 to 40.0 parts by mass of photopolymerization initiators expressed by formula (1) below, and 0.3 to 5.0 parts by mass of thioxanthone-based sensitizers relative to all photopolymerizable components representing 100 parts by mass.
