Claims
- 1. A dioxazine compound represented by the formula (1): ##STR12## wherein R represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; and each of Z.sup.1 and Z.sup.2 independently represents a hydrogen atom or a halogen atom, said compound having a plate-like crystal form having a vertical and horizontal ratio of 1:1 to 1:4 in the mean value of crystal size.
- 2. A reaction product obtained by subjecting a compound represented by the formula (2): ##STR13## wherein R represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; and each of Z.sup.1 and Z.sup.2 independently represents a hydrogen atom or a halogen atom, to ring closure reaction in the presence of a compound represented by the formula (3): ##STR14## wherein R' represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; each of Z.sup.3 and Z.sup.4 independently represents a hydrogen atom or a halogen atom; each of X and Y independently represents a substituent; i is a number of 1 to 6; and j is a number of 0 to 6, but i+j=1 to 6; said substituent represented by X is --A--(CH.sub.2).sub.1 --B or a phthalimidoalkyl group and said substituent represented by Y is --A'--(CH.sub.2).sub.n --B' or a phthalimidoalkyl group (wherein A represents a divalent bonding group selected from --SO.sub.2 --, --CO--, --S--, --CH.sub.2 NHCO--, --O--, --CONR.sup.3 --, --SO.sub.2 NR.sub.4 -- and NR.sup.5 (wherein each of R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 independently represents a hydrogen atom or a saturated or unsaturated aliphatic or aromatic group which may contain a chalcogen atom, a nitrogen atom and/or a halogen atom); A' represents a divalent bonding group selected from --SO.sub.2 --, --CO--, --S--, --CH.sub.2 NHCO--, --O--, CR.sup.1 R.sup.2 --, --CONR.sup.3 --, --SO.sub.2 NR.sup.4 -- and NR.sup.5 (wherein each of R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 independently represents a hydrogen atom or a saturated or unsaturated aliphatic or aromatic group which may contain a chalcogen atom, a nitrogen atom and/or a halogen atom); each of B and B' independently represents a bonding group selected from --OR.sup.6 (wherein R.sup.6 represents a hydrogen atom, a metal atom or a saturated or unsaturated aliphatic or aromatic group which may contain a chalcogen atom, a nitrogen atom and/or a halogen atom), --NR.sup.7 R.sup.8 and --R.sup.9 (wherein each of R.sup.7, R.sup.8 and R.sup.9 independently represents a hydrogen atom or a saturated or unsaturated aliphatic or aromatic group which may contain a chalcogen atom, a nitrogen atom and/or a halogen atom); and each of n and 1 independently represents a number of 0 to 8)), said reaction product being in plate-like crystal form.
