2. Description of the Related Art Originally, most of epoxy resins were used as adhesives by making use of the properties of cured products. Subsequently, new uses such as paints and glass fiber reinforced plastics have increased due to the excellent mechanical strength and electrical insulation properties of the cured products. Recently, applications for electric and electronic materials such as laminates, molding materials, Applications such as stop materials have become noticeable. In the wake of a series of fires and fire accidents in home appliances, the demand for flame-retardant insulating materials has increased, and the use of flame-retardant epoxy resins has started in insulating materials, vehicles, ships, aircraft, and building materials. It is also used for flame retardation of housings and the like.

Conventionally, as a method for making an epoxy resin flame-retardant, for example, as described in "Plastic Age", June 1991, pp. 146-153, glycidyl ether of tetrabromobisphenol A, bromide A method using a halogen-containing epoxy compound such as polyglycidyl ether of phenolized novolak or a halogen-containing organic compound such as decabromobiphenyl ether is known. However, these flame retardants are heat resistant,
There is a possibility that electric insulation and the like may be reduced, and that toxic gas may be generated at the time of fire combustion. In addition, since a communication network was paralyzed by a fire at a nuclear power plant or a telephone office, it has been desired to suppress toxic gas generation and reduce smoke generation.

On the other hand, as phosphorus-based flame retardants,
Inorganic compounds such as polyphosphates and red phosphorus, and organic compounds such as phosphate esters, particularly triphenyl phosphate, are widely used. However, these phosphorus-containing flame retardants have a problem that they lower the moisture resistance and heat resistance of the epoxy resin. Examples of the phosphorus-containing epoxy compound include aromatic compounds in which a phosphorus atom is incorporated into a skeleton chain (JP-A-61-134395, JP-A-Hei.
JP-A-272014), aliphatic ether compounds (JP-A-62-223215), and aromatic compounds having a phosphorus atom in the side chain (JP-A-5-39345, JP-A-6-239345).

[0005] However, compounds in which an aromatic ring is not directly bonded to a phosphorus atom (JP-A-62-223215 and JP-A-61-148219) have low heat resistance and do not have the same properties as triphenylphosphine oxides. Compound having two or more aromatic rings bonded to a phosphorus atom (see JP-A-61-13)
No. 4395, JP-A-5-39345) are expensive and the purification of synthetic products is not easy. One aromatic ring on the phosphorus atom

No. 10, Vol. 1984, pp. 2404-2405), but there is a problem that industrialization is difficult because sodium hydride, which has high reactivity and is not easy to handle, is used as an acid acceptor. In addition, since benzene is used as the solvent, it takes a long time to distill off the solvent, and there is a problem that the side reaction and the oligomerization of the phosphorus-containing epoxy compound are apt to proceed due to heat applied during that time, and the color is easily discolored. On the other hand, as another method, there is a method in which triethylamine is used instead of sodium hydride and toluene is used instead of benzene in the above synthesis example (European Patent Application No. 92/02705, page 9). It does not lead to the solution of the problem caused by the long time.
