Beschreibung
Zusammenfassung:	Fluorescent brightener salts of the formula in which A denotes the anion of an anionic cellulose fluorescent brightener, R1 denotes alkyl, alkenyl, aralkyl, aryl or cycloalkyl, R2, R3 and R4 denote hydrogen or R1, or together, including the N atom, form a heterocyclic ring, and n denotes 1 or 2, are suitable for incorporation into paper-coating slips. The brightened coating slips are distinguished, inter alia, by the fact that the achievable greying limit is very high.
