S), styrene-based resins such as ABS have good mechanical properties, and excellent electrical insulation properties and moldability, and thus are widely used in recent years, such as OA equipment, housings of home electric appliances, and automobile parts. However, since styrene resins are flammable, flame retardancy is required for safety. In particular, in the fields of OA equipment, home electric appliances, etc., they are used indoors, but are exposed to fluorescent light and light coming from outside, so that light resistance is emphasized. Conventionally, various halogenated organic compounds have been proposed for imparting flame retardancy to styrene resins. Typically, tetrabromobisphenol A (TBA), decabromodiphenyl ether (DBDPE), brominated epoxy resin, and the epoxy group of this brominated epoxy resin are blocked with tribromophenol (TBP). Are known. Particularly, the above two are widely used because they are inexpensive. However, when TBA is blended with a styrene-based resin, there is a drawback that heat resistance and light resistance are significantly reduced, and an epoxy resin blocked with DBDPE and TBP has a drawback of reducing light resistance. In addition, the brominated epoxy resin has high adhesion to metal parts such as an extruder at the time of melt-kneading and a molding machine at the time of molding, so that the attached matter is exposed to a high temperature for a long time, causing discoloration and deterioration. As a result, it is mixed as a foreign substance into a compound or a molded product.
