1. A curable composition comprising a polymerizable heterocyclic compound (A) and an initiator (C),
wherein the polymerizable heterocyclic compound (A) is a compound represented by the following formula (A1):

OG Complex Work Unit Chemistry
wherein, in the formula (A1), RA1, RA2, and RA3 each are an aromatic-ring-containing group, at least one of RA2 and RA3 is a group represented by the following formula (A2):

OG Complex Work Unit Chemistry
Wherein —NH— groups bonded to the triazine ring each are bonded to the aromatic ring in RA1, RA2, and RA3;
in the formula (A2), Ra1 and Ra2 are each independently an alkyl group having 1 or more and 4 or less carbon atoms, an alkoxy group having 1 or more and 4 or less carbon atoms, or a halogen atom;
n1 and n2 are each independently an integer of 0 or more and 4 or less;
Ra3 and Ra4 are each independently a hydrogen atom, an alkyl group having 1 or more and 4 or less carbon atoms, a halogenated alkyl group having 1 or more and 4 or less carbon atoms, or a phenyl group;
Ra3 and Ra4 may be bonded to each other to form a ring;
RA4 is a radically polymerizable group-containing group or a cationically polymerizable group-containing group; and
when RA2 and RA3 each are a group represented by the formula (A2), RA2 and RA3 each have a radically polymerizable group-containing group or each have a cationically polymerizable group-containing group.
