Abstract:
To provide an active-energy-ray-curable composition including a compound represented by General Formula (I) below:
where in the General Formula (I), R is hydrogen or a methyl group; A is a structure expressed by one selected from the group consisting of Structural Formulas (II) to (VII) below, each of which may have a substituent such as an alkyl group or an alkoxy group, or both; j and k in the Structural Formulas (VI) and (VII) are an integer of 0 or more; X denotes a substituent including a heteroatom; n is an integer of 0 or more, m is an integer of 1 or more, and n+m is 3 or more, or n is an integer of 0 and m is an integer of 2; and wavy lines in the Structural Formulas (II) to (VII) each independently denote a bond with X or a (meth)acryloyl group (H2C═CR—C(═O)—):
