Abstract

Embodiments provide an active energy curable resin composition containing (A) 100 parts by mass of a UV-absorbing polymer and (B) 20-600 parts by mass of a polyfunctional (meth)acrylate. The UV-absorbing polymer (A) contains: (a1) 10-60 mol % of a structural unit derived from a (meth)acrylate including one or more of one or more types of backbone selected from the group consisting of a benzotriazole backbone, a triazine backbone, and a benzophenone backbone per molecule; (a2) 10-50 mol % of a structural unit derived from an alkyl (meth)acrylate; and (a3) 10-70 mol % of a structural unit derived from a compound including one or more isocyanate groups per molecule; the sum of the structural unit derived from a (meth)acrylate of component (a1), the structural unit derived from an alkyl (meth)acrylate of component (a2), and the structural unit derived from an isocyanate-group-including compound of component (a3) being 100 mol %.
