<p>Dyes of the formula <IMAGE> (I) where R1 is hydrogen, C1-C6-alkyl or C2-C6-alkenyl, R2 and R3 independently of one another are hydrogen, C1-C5-alkyl or C2-C5-alkenyl, R4 is C1-C12-alkyl or hydroxy-C2-C4-alkyl, X(-) is one equivalent of an anion, mis from 0 to 5 and n is from 0 to 5, with 1</=(m+n)</=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.</p> |
