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 C4-20 linear hydrocarbon group optionally containing an epoxy group, an (n4)-valent C4-20 cyclic 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; R1 and R2 are each independently a hydrogen atom or a C1-10 alkyl 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.
提供一种低粘度和高阳离子固化性的环氧树脂组合物。其中,化学式(1)的环氧化合物为:(在化学式(1)中,A是一个(n4)价的C4-20线性烃基,可选含有环氧基,一个(n4)价的C4-20环烃基,可选含有环氧基,或者是由线性烃基和环烃基的组合形成的(n4)价基团;R1和R2各自独立地是氢原子或C1-10烷基;n1是2到6的整数;n2是2的整数;n3是1的整数;n4是3到8的整数)。例如,A是由丁烷、戊烷或己烷去除(n4)个氢原子形成的(n4)价有机基团,或者是由环丁烷、环戊烷、环己烷、环氧基环己烷、烷基取代的环氧基环己烷、双环庚烯或双环辛烯去除(n4)个氢原子形成的(n4)价有机基团。
