There is provided an epoxy resin composition having low viscosity and a high cationic curing property. An epoxy compound of Formula (1): (in Formula (1), A is an (n4)-valent Clinear hydrocarbon group optionally containing an epoxy group, an (n4)-valent Ccyclic hydrocarbon group optionally containing an epoxy group, or an (n4)-valent group of a combination of the linear hydrocarbon group and the cyclic hydrocarbon group; Rand Rare each independently a hydrogen atom or a Calkyl group; n1 is an integer of 2 to 6; n2 is an integer of 2; n3 is an integer of 1; and n4 is an integer of 3 to 8). For example, A is an (n4)-valent organic group formed by removing (n4) hydrogen atoms from butane, pentane, or hexane, or an (n4)-valent organic group formed by removing (n4) hydrogen atoms from cyclobutane, cyclopentane, cyclohexane, epoxycyclohexane, alkyl-substituted epoxycyclohexane, bicycloheptene, or bicyclooctene.

Polyfunctional epoxy compound

There is provided an epoxy compound that provides properties of cured products combining high transparency with high flexural strength by being thermally cured while maintaining advantageous handling properties in a liquid state thereof; and a method for producing a composition by using the epoxy compound. A method for producing an epoxy compound of Formula (1): (in Formula (1), n1, n2, and n3 are individually any one of integers of 2 to 6; n4, n5, and n6 are individually an integer of 2; n7, n8, and n9 are individually an integer of 1; and R, R, R, R, R, and Rare independently a hydrogen atom or a Calkyl group), including: reacting cyanuric chloride with a Calkenol and reacting the obtained compound having an unsaturated bond with a peroxide.

Method for producing epoxy compound having cyanuric acid skeleton

There is provided a curable composition having a low viscosity and high cationic curability. A curable composition including an epoxy compound of Formula (1): [in Formula (1), A is a monocyclic aliphatic hydrocarbon group optionally containing an epoxy group; R, R, Rand Rare independently a hydrogen atom or a Calkyl group; n1 and n2 are independently an integer of 2 to 6; n3 and n4 are individually an integer of 2; and n5 and n6 are individually an integer of 1], and an acid generator.
