PROBLEM TO BE SOLVED: To provide an active-ray curable inkjet ink composition that achieves improvements in both stretchability and surface curability.SOLUTION: The present invention relates to an active-ray curable inkjet ink composition. The composition contains (a) a photopolymerizable oligomer that has a weight average molecular weight of 5,000 or more and 100,000 or less and contains 10 or more photopolymerizable functional groups per 1 molecule, (b) a photopolymerizable monomer, and (c) a photopolymerization initiator, where a content of the photopolymerizable oligomer is 3 mass% or more and 30 mass% or less relative to the total mass of the composition.SELECTED DRAWING: None 【課題】延伸性および表面硬化性をいずれも高めた活性光線硬化型のインクジェットインク組成物を提供する。【解決手段】本発明は、活性光線硬化型のインクジェットインク組成物に係る。前記組成物は、（ａ）重量平均分子量が５，０００以上１００，０００以下であり１分子あたり１０個以上の光重合性官能基を有する光重合性オリゴマー、（ｂ）光重合性モノマー、および（ｃ）光重合開始剤を含有し、前記光重合性オリゴマーの含有量は、前記組成物の全質量に対して３質量％以上３０質量％以下である。【選択図】なし
