摘要

Metal-free compounds of the formula, ##STR1## and 1:1 copper complexes of metallizable metal-free compounds of said formula and internal and external salts of metal-free compounds of said formula and of 1:1 copper complexes of metallizable metal-free compounds of said formula, whereinPPeach Q is independently linear or branched C.sub. 2-6 alkylene; linear or branched C.sub.2-6 alkylene interrupted by --O--, --S-- or --NR.sub.4 --; linear or branched C.sub.3- 6 alkylene monosubstituted or disubstituted by hydroxy or --*NHCO--CH.sub. 2 --, wherein the * denotes the atom attached to the --NR.sub.4 -- radical, PPeach R.sub.1 is independently hydrogen, halo, nitro, C.sub. 1-4 alkyl, C.sub.1-4 alkoxy, (C.sub.1-4 alkyl)carbonylamino, --SO.sub.2 NR.sub.3 R.sub.4, --CONR.sub.4 --C.sub.6 H.sub.5 or benzamido, P PR.sub.2 is hydrogen, hydroxy, halo, nitro, C.sub.1-4 alkyl, C. sub.1-4 alkoxy, (C.sub.1-4 alkyl)carbonylamino or --NHCONR.sub. 3 R.sub.4, PPX is --NR.sub.5 R.sub.6 or --N.sup. R. sub.7 R.sub. 8 R.sub.9 An.sup., wherein R.sub.5 -R.sub.9 and An. sup. are as defined in the specification, andPPn is 0 or 1 PPwhereinPPeach R.sub.3 is independently hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkyl monosubstituted by hydroxy, halo, cyano or C.sub.1-4 alkoxy, andP Peach R.sub.4 is independently hydrogen or C.sub.1-4 alkyl, are useful, as such and in the form of solid and liquid aqueous dye preparations as direct dyes for dyeing or printing hydroxy-group or nitrogen-containing organic substrates, such as textiles consisting of or containing cellulose, leather and especially paper; they are also suitable for dyeing glass and products thereof and in inks.
