PROBLEM TO BE SOLVED: To provide: a polymerization inhibitor enabling thermal stability and storage stability of a radical curable composition to be improved without changing the curing property of the radical curable composition; and a radical curable composition using the polymerization inhibitor.SOLUTION: There is provided the radical curable composition which is obtained by using as a raw material, at least a radical curable oligomer (A) and a polymerization inhibitor (C). In the radical curable composition, a compound having a condensed polycyclic aromatic skeleton represented by the general formula (1) is used as the polymerization inhibitor (C). (1), where n represents an integer of 1 to 4, R represents any of a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, an alkoxyalkyl group, a glycidyl group, a hydroxyalkyl group or an aryloxyalkyl group, R may be same or different when there are a plurality of OR groups. |
