PROBLEM TO BE SOLVED: To provide an ultraviolet ray-curable inkjet ink which can decorate a resin film, and which especially exhibits good flexibility at the time of insert molding, and which is excellent in flexibility after the insert molding and can even suppress yellowing by long term exposure to high temperature.SOLUTION: An ultraviolet ray-curable inkjet ink comprises a reactive monomer, a reactive oligomer, and a photoinitiator. The reactive monomer is a polymerizable monofunctional monomer containing in the molecule a cyclic structure except an aromatic ring and a lactam ring. The photoinitiator is a hydroxyketone-based photoinitiator. |
