Zusammenfassung:	To provide a photohardenable ink for discharging capable of favorably performing printing or forming while maintaining discharging properties.SOLUTION: The photohardenable ink for discharging includes a radically polymerizable compound, a photoinitiator, and a thixotropic agent, where the first viscosity measured with a rate of share of 10,000 s-1 is 1,000 mPa s or less, and the second viscosity measured with a rate of share of 10-1 s-1 after applying a share force by a rate of share of 10,000 s-1 for 30 sec. is 10,000 mPa s or more.SELECTED DRAWING: None 【課題】吐出性を維持しつつ好適に印刷又は造形を行える光硬化性吐出用インクを提供する。【解決手段】光硬化性吐出用インクは、ラジカル重合性化合物と、光開始剤と、チキソ剤とを含有し、剪断速度１００００ｓ−１で測定した第１の粘度が１０００ｍＰａ・ｓ以下であり、剪断速度１００００ｓ−１で剪断力を３０秒間加え続けた後に、剪断速度を１０−１ｓ−１とした状態で測定した第２の粘度が１００００ｍＰａ・ｓ以上である。【選択図】なし
