Abstract:
An epoxy resin composition, comprising:(A) a phenol epoxy resin represented by the following formula (I) ##STR13## wherein each R.sup.1 is the same or different and is independently selected from the group consisting of hydrogen, C.sub.1 to C.sub.6 hydrocarbyl groups, C.sub.6 to C.sub.10 aromatic groups, and C.sub.1 to C.sub.6 hydrocarbyl-substituted C.sub.6 to C.sub.10 aromatic groups,each R.sup.2 is the same or different and is independently selected from the group consisting of hydrogen, C.sub.1 to C.sub.6 hydrocarbyl groups, C.sub.6 to C.sub.10 aromatic groups, C.sub.1 to C.sub.6 hydrocarbyl-substituted C.sub.6 to C.sub.10 aromatic groups, ##STR14## wherein R.sup.3 is selected from the group consisting of hydrogen, C.sub.1 to C.sub.10 hydrocarbyl groups, C.sub.6 to C.sub.10 aromatic groups, and C.sub.1 to C.sub.6 hydrocarbyl-substituted C.sub.6 to C.sub.10 aromatic groups, and each R.sup.4 is the same or different and is independently selected from the group consisting of hydrogen, C.sub.1 to C.sub.6 hydrocarbyl groups, C.sub.6 to C.sub.10 aromatic groups, and C.sub.1 to C.sub.6 hydrocarbyl-substituted C.sub.6 to C.sub.10 aromatic groups,n is an integer of 0 or 1;(B) an epoxy resin different from formula (I); and(C) a curing agent,wherein the phenol epoxy resin (A) is present in an amount of 1 to 99 wt % based on the total weight of the epoxy resins, the epoxy resin (B) is present in an amount of 1 to 99 wt % based on the total weight of the epoxy resins, and the curing agent is present in an amount of 1 to 90 wt % based on the total weight of the epoxy resin composition; wherein, said phenol epoxy resin is an ortho-biphenyl epoxy resin.
