Abstract: The compounds of the formula where Y is hydrogen, chlorine, bromine or nitro, Z is hydrogen, chlorine, bromine, a sulfonic ester group or unsubstituted or substituted sulfamyl, X is -O- or R is alkylene which may or may not be interrupted by oxygen or m is 0 or 1, p is 1 or 2, R1 and R2 independently of one another are each hydrogen, unsubstituted or substituted alkyl, alkenyl, cycloalkyl, aralkyl, or aryl, or R1 and R2 together with the nitrogen form a heterocyclic structure, R3 is hydrogen or unsubstituted or substituted alkyl, R6 and R7 independently of one another are each hydrogen, unsubstituted or substituted alkyl, alkoxy or acylamino, K is a radical of a coupling component, A(-) is an anion, R4 is unsubtituted or substituted alkyl and R5 is hydrogen or C1-C4-alkyl, and the radical may furthermore be an unsubstituted or substituted piperazine radical, are useful for dyeing acid-modified fibers, leather and in particular paper.

Abstract: The invention relates to a process for the preparation of largely salt-free aqueous solutions of ionic dyestuffs by electrodialysis, which is characterised in that the flow rate of diluate (= solution to be treated) is chosen to be less than that of the concentrate.

Abstract: Dihydroquinacridones, quinacridones and quinacridonequinones are prepared by cyclisation of 2,5-dianilino-3,6-dihydroterephthalic acid derivatives or 2,5-dianilinoterephthalic acid derivatives in liquid or solid aggregate state or as a solution, in each case in finely divided form, if appropriate in the presence of an oxidising agent.
