Cationic dyes and their use

Abstract

Abstract 1. A cationic dye of the formula see diagramm : EP0061624,P10,F2 where F is an (n+m+p)-valent radical of a quinophthalone or a xanthene dye, R**1 is hydrogen or C1 -C4 -alkyl, R**2 and R**3 independently of one another are C1 -C14 -alkyl, C2 -C4 -hydroxylalkyl, C5 -C8 -cycloalkyl, 2-aminocyclopentylmethyl, benzyl, N,N-di-C1 -C5 -alkylamino-C2 -C4 -alkyl, N-C5 -C8 -cycloalkylamino-C2 -C4 -alkyl or N-C1 - or C2 -alkyl-N-C5 -C8 -cycloalkylamino-C2 -C4 -alkyl, and R**2 can also be hydrogen if n is 0, or see diagramm : EP0061624,P10,F3 is a pyrrolidine, imidazole, 2-ethyl-4-methylimidazole, morpholine, piperazine, N'-C1 -C4 -alkylpiperazine, pyridine or 2-, 3- or 4-methylpyridine radical or is see diagramm : EP0061624,P10,F4 R**4 is hydrogen or methyl, R**5 is C1 -C12 -alkyl, C2 -C4 -hydroxyalkyl or benzyl, X(cation) is one equivalent of an anion, M(anion) is H(anion) or one equivalent of a cation, z is 1 or 2, p is 0 or 1, m is 0, 1, 2, 3 or 4 and n is 0, 1, 2, 3 or 4, and 1 =< (m+n) =< 4.
