Abstract

An object of the present invention is to provide a cationic polymerization initiator which is thermally latent and can control the initiation of polymerization of a compound having a cationically curable functional group by adjusting the temperature, a curable resin composition containing the cationic polymerization initiator, a bonded body of a cured product and a metal in which discoloration of the cured product and the metal under humid heat conditions is suppressed, use of a composition containing the cationic polymerization initiator and an amine compound as a thermal-latent cationic polymerization initiator, a method for curing a curable resin composition containing the cationic polymerization initiator and a compound having a cationically curable functional group, a method for producing a cured product using the cationic polymerization initiator, and a cured product produced by the production method. The thermal-latent cationic polymerization initiator of the present invention includes a specific Lewis acid-type cationic polymerization initiator and an amine compound, wherein the Lewis acid-type cationic polymerization initiator and a moiety of the amine compound form a complex, a remaining moiety of the amine compound is present in a state free from the Lewis acid-type cationic polymerization initiator, and a mole ratio of an amino group contained in the free amine compound to 1 mole of a boron atom contained in the Lewis acid-type cationic polymerization initiator is from 0.15 to 1.70.
