Disclosed is a shrink-resistant curable composition that provides a cured product having high heat resistance. A polymerizable substituent is introduced into a 1,1-'binaphthyl skeleton in which the 2,2'-position represented by the following general formula (I) is connected by a divalent substituent or an atom. A curing shrinkage-resistant curable composition containing a polymerizable compound and a polymerization initiator capable of polymerizing the polymerizable substituent is used. In the above general formula (I), (R) m or (R) n means m or n identical or different substituents, respectively, which can be substituted on the naphthalene ring to which they are bonded. It may be bonded to any carbon atom, and X is a divalent substituent or atom. [Selection figure] None |
