Beschreibung
Zusammenfassung:	It is an object of the present invention to provide a bisbenzoxazinone compound which does not substantially contain an alkali metal salt, has high purity and provides a resin composition having excellent resistance to hydrolysis when it is contained in a resin, a production method thereof, and a resin composition comprising the compound. The present invention is a bisbenzoxazinone compound represented by the following formula (4): (R 1 and R 2 are each independently a hydrogen atom, hydroxyl group, alkyl group having 1 to 3 carbon atoms, or the like), and has (i) a purity of 98 % or more, (ii) a content of a compound represented by the following formula (7) of less than 0.15 wt%: (iii) a maximum peak in the measurement of the light reflectance at a visible range of its powder at 380 to 480 nm and a maximum light reflectance of 100 to 120 %, (iv) a metal sodium content of less than 50 ppm and (v) a YI value of -10 to 10.
