Abstract: Quaternary compounds of the formula ##STR1## wherein K.sym. denotes a cationic organic radical,X denotes a linking member,R denotes the radical of a heterocyclic reactive group,m denotes the numbers 1 or 2,n denotes the numbers 1 or 2 andAn.crclbar. denotes an anion,can be used for increasing the affinity of anionic dyestuffs for natural or synthetic fiber materials containing nitrogen or hydroxyl groups.

Abstract: Sulphur dyestuffs which can be obtained by sulphurizing, in a manner which is in itself known, the residual mixtures obtained on dinitrating anthraquinone or on dinitrating by-products from the preparation of 1-nitroanthraquinone and partially isolating 1,5- and 1,8- and, if appropriate, 1,6- and 1,7-dinitroanthraquinones, optionally after prior reduction and/or hydroxylation and/or introduction of nitro groups, and their use in dyeing cellulose or material containing cellulose.
