ABSTRACT:
The present invention provides a novel epoxy compound, which can be converted into a cured epoxy resin product having liquid crystal properties by curing with a curing agent. Since the cured epoxy resin product of the present invention exhibits good heat conductivity, it is also useful as an insulating material requiring high heat releasability such as a printed circuit substrate and the like.
