(57) [Problem] To provide an active energy ray-curable composition having excellent curability and excellent flexibility of a cured product. A composition comprising (A) a (meth) acrylate represented by the following formula (1) and (B) a (meth) acrylate represented by the following formula (2), wherein the component (B): Is 0.1 to 20% by weight based on the total amount of the components (A) and (B). Embedded image Embedded image [However, in the formulas (1) and (2), R 1 and R 5 are a hydrogen atom or a methyl group, and R 2 is an alkylene group. R 3 and R 4 is an independent hydrogen atom and / or an alkyl group having 4 or less carbon atoms, or a saturated or unsaturated hydrocarbon group forming a 5- or 6-membered ring together. n is an integer of 1 to 6, and m represents an integer of 1 to 20. The dotted line in the 5-membered imide ring means a single bond or a double bond. ] |
