摘要： According to the present invention, it is possible to provide a photocurable composition which comprises a cyclic compound (a) represented by formula (1), an episulfide compound (b), and a photopolymerization initiator (c). In a preferred embodiment, the proportion of the cyclic compound (a) in the photocurable composition is 5-80 mass %, the proportion of the episulfide compound (b) is 20-95 mass %, and the proportion of the photopolymerization initiator (c) is 0.1-10 parts by mass per 100 parts by mass of the sum of the cyclic compound (a) and the episulfide compound (b). In the formula, C represents a carbon atom, X represents S, Se, or Te, and a to f are integers of 0-3, provided that 8≥(a+c+e)≥1, 8≥(b+d+f)≥2, and (b+d+f)≥(a+c+e).

摘要： 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·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° C. (a) A compound which has two episulfide groups per molecule and which is represented by formula (1): wherein m represents an integer from 0 to 4 and n represents an integer from 0 to 2 (b) A compound having one or more thiol groups per molecule.
