摘要：
A stilbene type epoxy resin represented by the general formula (1) consisting of 100 mol% of the cis -isomer, or 10 mol% or more of the cis -isomer and the rest of the trans -isomer:
wherein R 1 to R 8 are independently an acyclic or cyclic alkyl group having 1 to 6 carbon atoms, hydrogen atom or a halogen atom, and a production process thereof.
The invention provides a stilbene type epoxy resin having lower melting point and lower viscosity than the trans-stilbene type epoxy resin hitherto known.
