The present invention can provide a method for producing a cured product of an episulfide-based resin, the method having: (A) a step for obtaining a composition for a resin by mixing compound (a), compound (b) and a polymerization catalyst; (B) a step for pouring the composition for a resin into a mold; and (C) a step in which, by increasing the temperature of a heating medium, the composition for a resin is polymerized in the heating medium that contains a liquid having a thermal conductivity of 0.2 W/m&#xb7;K or higher, or in a shower of the heating medium. The maximum temperature of the heating medium in step (C) is 55 to 110&#xb0; C. wherein m represents an integer from 0 to 4 and n represents an integer from 0 to 2

Method for producing cured product of episulfide-based resin

According to the present invention, a curable composition can be provided, said composition being characterized by comprising: (A) an episulfide compound; and (B) a photobase generator comprising an organoboron compound represented by general formula (1) below: (In general formula (1), R, R, R, Rand Rmay be the same as or different from one another and independently represent an alkyl group having 1 to 8 carbon atoms; and Ar, Arand Armay be the same as or different from one another and independently represent a group selected from the group consisting of a phenyl group, a naphthyl group, an anthracenyl group and a phenanthryl group, each of which may have a substituent selected from the group consisting of an alkyl group, an aryl group, an alkenyl group, a cycloalkyl group and a heterocyclic group.)
