PROBLEM TO BE SOLVED: To provide a polymerizable composition having a low viscosity, an extremely fast curing rate, and excellent low odor property and storage property, and an active energy ray-curable inkjet ink using the composition.SOLUTION: The polymerizable composition comprises a compound having a (meth)acryl group, and an allyl ether group or a vinyl ether group in the same molecule. With radicals generated by the combination of the above compound with a radical polymerization initiator, a polymerization reaction, a crosslinking reaction or the like can be reliably carried out in a short time for curing the composition, and further, a low viscosity, low odor and high storage stability can be achieved. 【課題】低粘度で硬化速度が極めて速く、かつ低臭気、保存安定性に優れた重合性組成物及びそれを用いた活性エネルギー線硬化型インクジェットインキを提供することである。【解決手段】同一分子中に（メタ）アクリル基とアリルエーテル基もしくはビニルエーテル基とを有することを特徴とする化合物を含んでなる重合性組成物を用いることによって、ラジカル重合開始剤との組み合わせにより発生したラジカルによる重合反応、架橋反応などをより短時間に確実に硬化することが可能となり、さらには低粘度、低臭気、高い保存安定性を示すことが可能となる。【選択図】なし
