To provide an ink composition that has high discharge stability even though it is an ink composition to make a contact with a plastic member provided in an inkjet recording device and to be inkjet-discharged by the inkjet recording device.SOLUTION: The present invention provides an n ink composition to make a contact with a plastic member provided in an inkjet recording device and to be inkjet-discharged by the inkjet recording device. The ink composition contains an organic solvent, the organic solvent containing the following organic solvent A. The organic solvent A is at least one selected from the group consisting of an alkylamide solvent (a1) and a cyclic amide solvent (a2).SELECTED DRAWING: None 【課題】インクジェット記録装置に備えられるプラスチック部材と接触し、インクジェット記録装置によりインクジェット吐出されるインク組成物であっても、吐出安定性の高いインク組成物を提供する。【解決手段】インクジェット記録装置に備えられるプラスチック部材と接触し、インクジェット記録装置によりインクジェット吐出されるインク組成物であって、有機溶剤を含有し、前記有機溶剤は、下記有機溶剤Ａを含有するインク組成物である。有機溶剤Ａ：アルキルアミド系溶剤と環状アミド系溶剤からなる群より選ばれる少なくとも１つ【選択図】なし
