PROBLEM TO BE SOLVED: To provide an aqueous ink containing a water-insoluble colorant and having excellent storage stability.SOLUTION: An ink contains a water-insoluble colorant, a polymer, a polyalkylene wax, and water. Monomers constituting the polymer comprise at least one monomer selected from methacrylic acid derivatives and at least one monomer selected from acrylic acid derivatives. Thus, it is possible to provide an aqueous ink containing a water-insoluble colorant and having excellent storage stability.SELECTED DRAWING: None 【課題】水不溶性着色剤を含有し、保存安定性が良好な水性インクの提供。【解決手段】水不溶性着色剤、ポリマー、ポリアルキレンワックス、及び水を含有するインクであって、前記ポリマーを構成するモノマーが、メタクリル酸誘導体、及びアクリル酸誘導体のそれぞれから少なくとも１種類ずつ選択されるモノマーを含有するインクにより、水不溶性着色剤を含有し、保存安定性が良好な水性インクを提供できた。【選択図】なし
