CURABLE COMPOSITION, CONNECTED STRUCTURES, AND MERCAPTO-CONTAINING (METH)ACRYLATE COMPOUND

摘要

Provided is a curable composition which can yield a cured product that exhibits a reduced moisture absorption and an enhanced bond strength to a member to be connected. Also provided is a novel (meth)acrylate compound containing a thiol group, which is usable as a material for the curable composition. The curable composition contains both a mercapto-containing (meth)acrylate compound and an initiator for actinic energy ray polymerization. The novel mercapto-containing (meth)acrylate compound has a structure represented by general formula (31) [wherein R1 and R2 are each hydrogen or a methyl group; R3 and R4 are each a C1-5 alkylene group; X is a specific aromatic group; and Z1 and Z2 are each a mercapto group, or alternatively Z1 is a mercapto group with Z2 being a hydroxyl group].
