摘要

Benzthiazole compounds of the formula or a tautomeric form thereof, in which KK is the radical of a pyrimidine coupling compound as defined, W is a radical of the formula -CH2-NH-CO-C1-C4-alkyl-Q(+) An(-) in which An is an anion and Q is a quaternary radical of the formula in which R1 to R6 independently of one another are a substituted or unsubstituted C1-C4-alkyl radical, or the radicals R1 and R2, or R3 and R4, or R3 and R4 and R5, together with the N atom, form a heterocyclic ring, m is the number 1, 2 or 3 and n is the number 0 or 1, and in which the benzene radicals A, B and/or C may be further substituted are particularly suitable as dyes for paper, brilliant yellow to orange dyeings which have, in particular, good wet-fastness and light-fastness, being obtained.
