PROBLEM TO BE SOLVED: To provide an electron beam-curable inkjet ink that achieves all of low odor, low migration, flexibility and high picture quality, and thereby that is applicable to packaging food products and medicines.SOLUTION: The electron beam-curable inkjet ink comprises a colorant and a polymerizable compound. The polymerizable compound comprises a monofunctional monomer and/or a bifunctional monomer, in which the total content of the monofunctional monomer and the bifunctional monomer is 95 to 100 wt.% in the whole amount of the polymerizable compound. The ink has a viscosity of 100 mPa s or less.SELECTED DRAWING: None 【課題】本発明は、低臭気、低マイグレーション、柔軟性、高画質の両立を実現することにより、食品・医薬品包装へ対応可能な電子線硬化型インクジェットインキを提供することを目的とする。【解決手段】着色剤、および、重合性化合物を含有する電子線硬化型インクジェットインキであって、前記重合性化合物が、単官能モノマーおよび／または二官能モノマーを含有し、単官能モノマーと二官能モノマーの合計含有量が、重合性化合物全量中９５〜１００重量％であり、インキの粘度が、１００ｍＰａ・ｓ以下であることを特徴とする、電子線硬化型インクジェットインキ。【選択図】なし
