Summary:PROBLEM TO BE SOLVED: To provide a hard coat laminate capable of preventing occurrence of peeling, splitting or cracking even after die-cutting is performed.SOLUTION: A curable composition for forming at least one layer between adjacent two hard coat layers constituting a hard coat laminate contains at least one kind of adhesion application component selected from among: mono(meth)-acrylate having an oxygen containing heterocyclic group, mono(meth)-acrylate having an aliphatic hydrocarbon group, mono(meth)-acrylate having a bridged cyclic hydrocarbon group, mono(meth)-acrylate having an allyloxy group, a polymer of the mono(meth)-acrylate having the allyloxy group, a multi-branched polyvinyl compound of which the weight average molecular weight is 1000 or more, di(meth)-acrylate having the bridged cyclic hydrocarbon group, alkanediol di(meth)-acrylate and polyalkylene glycol di(meth)-acrylate.SELECTED DRAWING: None 【課題】打ち抜き加工しても、剥離や割れ、クラックの発生を防止できるハードコート積層体を提供する。【解決手段】ハードコート積層体を構成する隣接した2層のハードコート層の少なくとも一方の層を形成するための硬化性組成物に、酸素含有ヘテロ環基を有するモノ(メタ)アクリレート、脂肪族炭化水素基を有するモノ(メタ)アクリレート、橋架環式炭化水素基を有するモノ(メタ)アクリレート、アリルオキシ基を有するモノ(メタ)アクリレート、アリルオキシ基を有するモノ(メタ)アクリレートの重合体、重量平均分子量1000以上の多分岐型ポリビニル化合物、橋架環式炭化水素基を有するジ(メタ)アクリレート、アルカンジオールジ(メタ)アクリレート及びポリアルキレングリコールジ(メタ)アクリレートから選択された少なくとも1種の密着付与成分を含有させる。【選択図】なし
