摘要

A radiation-curable ink composition comprises a polymerizable compound as Component A; a photopolymerization initiator as Component B; and two or more types of surfactants as Component C, wherein Component C comprises at least a surfactant that has a polymerizable group and a surfactant that does not have a polymerizable group, and the mass ratio of a content C 1 of the surfactant that has a polymerizable group and a content C 2 of the surfactant that does not have a polymerizable group is C 1 :C 2 = 35:1 to 1 :10.
