Abstract

The invention relates to triphendioxazine compounds of the formula (I) ##STR1## where the rings marked with A comprise, independently of one another, rings which are fused linearly in positions 2,3 and 9,10 or angularly in positions 1,2 and 8,9 or 3,4 and 10,11 and have the radical members of the formula (i) --NR.sub.1 (CO).sub.m --NH--, (ii) --CR.sub.1 .dbd.CH--CO--NH--, (iii) --O--CH.sub.2 --CO--NH--, (iv) --CO--CH.dbd.CR.sub.1 --NH--, (v) --CO--NH--CO--NH--, (vi) --CO--NH--CR.sub.2 .dbd.N--, (vii) --CR.sub.2 .dbd.N--CO--NH--, (viii) --NR.sub.1 --(CO).sub.m --O--, (ix) --NH--CR.sub.1 .dbd.N--, (x) --NH--CO--CR.sub.1 .dbd.N--, (xi) --NH--CO--CHR.sub.1 --NH--, (xii) --NR.sub.3 --(CO).sub.m --NR.sub.4 --, (xiii) --NR.sub.5 --(CO).sub.m --NR.sub.6 --, (xiv) --NR.sub.4 --CO--O-- or (xv) --NR.sub.6 --CO--O--, PA1 m is 1 or 2, PA1 R.sub.1 is hydrogen, C.sub.1-4 alkyl or phenyl, preferably hydrogen, methyl or ethyl, PA1 R.sub.2 is hydrogen, C.sub.1-4 alkyl or phenyl, preferably hydrogen, methyl or ethyl, PA1 R.sub.3, R.sub.4, R.sub.5 and R.sub.6 independently of one another are hydrogen, a C.sub.1-8 alkyl radical, a substituted or unsubstituted phenyl, benzyl, naphthyl or benzanilide rad…
