ABSTRACT:
A novel quaternary phosphorus compound is a salt between tetraphenyl borate and a phosphonium having an aromatic group attached to a phosphorus atom through an oxygen atom. It is blended with an epoxy resin as a curing catalyst to form an epoxy resin composition which flows smoothly and quickly cures into a product having improved moisture resistance and adhesion.
