Abstract

Disazo and polyazo compounds of the formula ##STR1## wherein each A is independently ##STR2## and each R.sub.3 is independently C.sub.1-4 alkyl, or PA0 each A, R.sub.3 and the ##STR3## radical to which they are attached, taken together, independently, are ##STR4## wherein each R.sub.21 is independently halo, C.sub.1-4 alkyl or C.sub.1-4 alkoxy, PA1 p is 0, 1 or 2, PA1 the * denotes the carbon atom attached to the --N.dbd.N-- radical, and PA1 the ** denotes the carbon atom attached to X, PA0 each R.sub.1 and the ##STR5## radical to which it is attached taken together, independently, are the radical of an aromatic or heterocyclic coupling component, PA0 each A.sub.1 and A.sub.2 taken together are --O--Me--O--, wherein Me is copper, cobalt, iron, nickel, manganese or zinc, or PA0 each A.sub.1 is hydroxy, and PA0 each A.sub.2 is independently hydrogen, hydroxy or C.sub.1-4 alkoxy, PA0 X is a direct bond or a bridging radical, PA0 each Y is independently a direct bond, C.sub.1-4 alkylene, --CO--NH--(CH.sub.2).sub.m --, --NH--CO--(CH.sub.2).sub.m -- or --SO.sub.2 --NR.sub.4 --(CH.sub.2).sub.m --, PA0 wherein PA1 R.sub.4 is hydrogen or C.sub.1-4 alkyl, PA1 m is 1, 2, 3 or 4, and PA1 the *…
