Abstract
A 1,1-bis(2,7-diglycidyloxy-1-naphthyl)alkane as an epoxy resin; a 1,1-bis(2,7-dihydroxy-1-naphthyl)alkane as an intermediate for said epoxy resin; a process for producing said intermediate comprising reacting 2,7-dihydroxy-1-naphthalene and an aldehyde; a process for producing said epoxy resin comprising reacting said intermediate and an epihalohydrin; and an epoxy resin composition comprising said epoxy resin and a curing agent. The epoxy resin has a low melt viscosity while exhibiting excellent heat resistance.
