Abstract

The invention is that of a new triphenodioxazine dye of the formula: ##STR1## wherein: ##STR2## K is independently selected from SO.sub.3 H and COOH; W=a substituted or unsubstituted arylene, alkylene or arylene-alkylene group; PA1 Y.sup.1 =Vinyl, .beta.-Sulfatoethyl, .beta.-Thiosulfatoethyl, .beta.-Halogenethyl-group, .beta.-Phosphatoethyl, and PA1 X=H. PA1 R, R.sub.1 and R.sub.2 are independently selected from hydrogen and substituted or unsubstituted alkyl. PA1 T is independently selected from hydrogen, Cl, Br, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, phenyl or phenoxy; and PA1 n is selected from 0, 1 or 2.
