Zusammenfassung: | Dyestuffs of the formula (I) wherein F stands for an organic chromophore and Z stands for radicals of the formulae (II) (III) wherein R1-R2 denote hydrogen, alkyl, cycloalkyl, alkenyl, aryl, aralkyl or a heterocyclic structure or R2 and R3 represent an optionally substituted amino group or together form a ring or R1 with R2 and/or R3 with R4 form a ring, A(-) denotes an anion, Y denotes an anionic group, m denotes 0-2 and n 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. |
