Abstract: Dyestuffs of the formula ##STR1## wherein F stands for an organic chromophore andZ stands for radicals of the formulae ##STR2## wherein R.sub.1 -R.sub.2 denote hydrogen, alkyl, cycloalkyl, alkenyl, aryl, aralkyl or a heterocyclic structure orR.sub.2 and R.sub.3 represent an optionally substituted amino group or together form a ring orR.sub.1 with R.sub.2 and/or R.sub.3 with R.sub.4 form a ring,A.sup.(-) denotes an anion,Y denotes an anionic group,m denotes 0-2 andn denotes 1-6,and wherein the chromophore and said radicals can carry further substituents, provided that the total number of anionic substituents is smaller than the total number of quaternary and quaternizable amino groups, are used for dyeing cellulose fibres, in particular paper.

Abstract: Basic copper-phthalocyanine dyestuffs of the formula ##STR1## in which Cu--Pc denotes the radical of an x-valent copper-phthalocyanine,A and B independently of each other denote an alkylene radical having 2 to 5 carbon atoms,R.sub.1 and R.sub.3 independently of each other denote hydrogen or an alkyl radical having 1 to 3 carbon atoms which is optionally substituted by hydroxyl, C.sub.1 - to C.sub.3 -alkoxy, halogen or an NH.sub.2 group,R.sub.2 denotes an alkyl group having 1 to 3 carbon atoms which is optionally substituted by hydroxyl, C.sub.1 - to C.sub.3 -alkoxy or halogen,n denotes the number 1 to 3,x denotes the value 1.8 to 2.5,or if n=1 and A=C.sub.2 H.sub.4, R.sub.1 +R.sub.2 denotes an ethylene bridge.find utility for dyeing paper.

Abstract: Basic copper phthalocyanine dyestuffs of the general formula ##STR1## in which Cu-Pc denotes the radical of an m+n-valent copper phthalocyanine radical,A denotes alkyleneB denotes a radical of the formula ##STR2## R.sub.1 denotes hydrogen or alkyl, R.sub.2, R.sub.3 and R.sub.4, independently of one another, denote alkyl which can be substituted by hydroxyl or alkoxy groups,R.sub.5 denotes hydrogen, alkyl or aminoalkyl,R.sub.6 and R.sub.7, independently of each other, denote hydrogen or alkyl which can be substituted by hydroxyl, alkoxy or amino groups, andR.sub.8 denotes hydrogen or alkyl, orR.sub.1 can form a closed ring with R.sub.2,R.sub.2 can form a closed ring with R.sub.3,R.sub.5 can form a closed ring with R.sub.6 and/orR.sub.6 can form a closed ring with R.sub.7,m denotes a number from 1.0 to 2.5,n denotes a number from 0 to 1.4,wherem+n is 1.8 to 2.5,p denotes 0, 1, 2 or 3 andX.sup.(-) denotes an anion,are used for dyeing paper.
