| abstract |
This invention provides an adamantane derivative that can provide a cured product having excellent optical properties such as transparency and lightfastness, long-term heat resistance, and electric characteristics such as permittivity, and an epoxy resin having an adamantane skeleton, a resin composition comprising them, and an optical electronic member using the resin composition. The adamantane derivative is represented by general formula (I). The epoxy resin having an adamantane skeleton is represented by general formula (V) or (VI). The resin composition comprises them. The optical electronic member uses the resin composition. In the formula, W represents, for example, a hydrogen atom, X represents a group represented by general formula (II), Y represents, for example, -O-, Z represents a group represented by formula (III) or (IV), R1 represents a methyl or ethyl group, R2 represents an alkyl group having 1 to 4 carbon atoms, k is an integer of 0 to 10, m is an integer of 0 to 14, n is an integer of 2 to 16, m + n = 16, and p and q are an integer of 0 to 5. |
