Abstract:
1. An active energy ray-curable ink composition comprising: (component A) monofunctional radically polymerizable monomers, (component B) a polyfunctional oligomer having a glass transition temperature of 20° C. or lower and an acrylate value of 300 g/value or more, and (component C) a bifunctional radically polymerizable monomer having a viscosity at 25° C. of 15 mPa·s or less, wherein the component A includes an N-vinyl compound and a compound represented by the following formula (I), the content of the N-vinyl compound with respect to the total amount of the ink composition is from 10 to 50% by mass, and the content of the component A with respect to the total amount of the ink composition is 70% by mass or more: wherein R represents a hydrogen atom or a methyl group, A the component B is an oligomer having an isophorone structure.
