PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition excellent in curability and hardness of a cured product, and to obtain a raw material diimide di (meth) acrylate in high yield and high purity, to obtain an odor and curability. Provided is a method for producing a composition having no problem of deterioration. An active energy ray-curable composition comprising a di (meth) acrylate having two cyclic imide groups and a mono (meth) acrylate having one cyclic imide group. Tetracarboxylic anhydride, dicarboxylic anhydride and amino alcohol are heated and stirred to obtain a mixture of a diol having two cyclic imide groups and a monool having one cyclic imide group. (Meta) A method for producing a composition for introducing an acryloyl group. |
