Beschreibung
Zusammenfassung:	1. Whitener-containing spinning dopes for the production of regenerated cellulose fibres, characterised in that they contain virtually water-insoluble lowmolecular brightener salts of the formula see diagramm : EP0060439,P8,F4 wherein A denotes the anion of a high-affinity anionic whitener for cellulose, R1 denotes optionally substituted alkyl, alkenyl, aralkyl, aryl or cycloalkyl, R2 , R3 or R4 independently of one another denote hydrogen or R1 , or either 2 or 3 of these radicals jointly form, with the inclusion of the N atom, a heterocyclic structure, and n denotes an integer > 0.
