Abstract
Abstract Aqueous dye formulations which contain one or more sparingly water-soluble, or water-insoluble, phthalocyanine-sulfonamides of the formula ##STR1## where A is a (n+m)-valent radical of copper phthalocyanine, cobalt phthalocyanine or nickel phthalocyanine which may be substituted by up to 4 chlorine or bromine atoms, R is hydrogen, alkyl of 1 to 5 carbon atoms or alkoxyalkyl of a total of 3 to 7 carbon atoms, R 1 is a substituted or unsubstituted aliphatic, cycloaliphatic, araliphatic or aromatic radical, or ##STR2## is a saturated 5-membered or 6-membered heterocyclic ring, X.sup.⊕ is H.sup.⊕, an alkali metal ion, (NH 4 ).sup.⊕ or ##STR3## (where R and R 1 have the above meanings), n is 2, 3 or 4 and m is 0 or 1, together with one or more conventional dispersing agents and humectants and with or without a disinfectant. The formulations give very fast prints and dyeings on cellulose and on cellulose-containing fibers.
