摘要： This invention provides a modified liquid epoxy resin having a low viscosity and a high performance, which is obtained by reacting a mixture of a bisphenol and a phenol aralkyl resin with an epiholohydrin. The bisphenol is preferable to be bisphenol F and is further preferable to have a bifunctional form purity as detected by gel permeation chromatography at UV 254 nm of not less than 95% by area in view of the fluidity. Moreover, the mixture of bisphenol and the phenol aralkyl resin is preferable to have a ratio of the phenol aralkyl resin of 10-70% by mass.
