Abstract

Metal-free compounds of the formula ##STR1## a 1:1 or 1:2 metal complex of a metallizable compound of said formula or a salt of a metal-free compound of said formula or of a 1:1 or 1:2 metal complex thereof each cation of which is independently a non-chromophoric cation, or a mixture, thereof, wherein PA1 F.sub.c is the radical of a water-soluble azo, formazan, phthalocyanine, azomethine, oxazine, thiazine, phenazine or triphenylmethane dye, PA1 each W is independently --NR.sub.1 --B.sub.1 --NR.sub.1 --, ##STR2## wherein B.sub.1 is linear or branched C.sub.2-6 alkylene; linear or branched C.sub.2-6 alkylene interrupted by --O-- or --NR.sub.1 --; linear or branched C.sub.3-6 alkylene monosubstituted by hydroxy or carboxy or disubstituted by hydroxy, ##STR3## wherein R.sub.2 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, carboxy or sulfo, and PA3 n is 0, 1, 2, 3 or 4, and PA2 m is 0 or 1, PA1 each X is independently a direct bond, --CO-- or --SO.sub.2 --, PA1 each a is independently 0 or 1, and b is 1 or 2, wherein PA1 each Alk is independently linear or branched C.sub.2-4 alkylene, and PA1 each R.sub.1 is independently hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkyl monosubstituted by…
