ABSTRACT:
Dyes of the formula ##STR1## where R.sup.1 is hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkenyl, R.sup.2 and R.sup.3 independently of one another are hydrogen, C.sub.1 -C.sub.5 -alkyl or C.sub.2 -C.sub.5 -alkenyl, R.sup.4 is C.sub.1 -C.sub.12 -alkyl or hydroxy-C.sub.2 -C.sub.4 -alkyl, X.sup..crclbar. is one equivalent of an anion, mis from 0 to 5 and n is from 0 to 5, with 1.ltoreq.(m+n).ltoreq.5, and F is an (m+n)-valent radical of a monoazo dye, a disazo dye, a polyazo dye, a quinophthalone, a bis-dioxazine, a compound of the 5,6-arylo-2-pyrone series, a naphtholactam dye, a triphenylmethane dye, a xanthene dye, a phthalocyanine, an indigoid, an anthraquinone dye containing one or more phenyl or naphthyl groups, a more highly fused carbonyl-containing dye, a quinacridone, a perylene-3,4,9,10-tetracarboxylic acid diimide, an anthrapyrimidine, a pyrazoloanthrone, a diaminonaphthoquinone, a naphthazarine or a naphthalene-1,4,5,8-tetracarboxylic acid diimide.
The dyes give brilliant wet-fast colorations on cellulose-containing fiber material, especially on paper. When used for wet-end coloring of paper, the waste water is virtually or completely colorless.
