Abstract: A radiation curable inkjet ink which has good surface curability even in air, and is capable of providing a cured product having low odor, good flexibility, and low-temperature impact resistance is described. In particular, radiation curable inkjet ink including from 20 to 40 parts by mass of a bifunctional urethane (meth)acrylate oligomer and from 50 to 80 parts by mass of a monofunctional monomer, based on 100 parts by mass of polymerizable components and an α-hydroxyketone oligomer and a benzophenone compound as photoinitiators are described.
