Claim 1

Uniformly dyed water-swellable cellulosic fibers, said fibers being fast to washing, dry cleaning, sublimation and light and having been produced by contacting water-swellable cellulose fibers subsequently or concomitantly with water, ethylene glycol or a derivative thereof and, while the fibers are still swollen, an essentially water-insoluble dye of the formula ##STR342## in which D is phenyl substituted by cyano, trifluoromethyl, methyl, fluoro, chloro, bromo, C 1 to C 4 alkylsulfonyl, phenylsulfonyl, ##STR343## anthraquinonyl; anthraquinonyl substituted by methyl, chloro, bromo or carboxyl; or benzoisothiazolyl substituted by nitro, chloro or bromo; R is hydrogen, C 1 to C 3 alkyl or phenyl; X is cyano, carbamoyl or ##STR344## R 1 and R 3 independently of one another are hydrogen; C 1 to C 8 alkyl; C 2 to C 8 alkyl substituted by hydroxy, C 1 to C 8 alkoxy, phenoxy, tolyloxy, cyclohexyloxy, benzyloxy, β-phenylethoxy, carboxyl, carboxylic ester with a total of 2 to 9 carbon atoms, carboxylic acyloxy with a total of 1 to 11 carbon atoms, C 1 to C 8 alkylaminocarbonyloxy, benzoylaminocarbonyloxy, tolylaminocarbonyloxy, chlorophenylaminocarbonyloxy, dichlorophenylaminocarbonyloxy or pyrrolidonyl; cyclohexyl, norbornyl; phenyl-C 1 to C 4 -alkyl; tolyl-C 1 to C 4 -alkyl; β-phenyl-β-hydroxy-ethyl; phenyl; phenyl substituted by fluoro, chloro, bromo, methyl, trifluoromethyl, ethyl, methoxy, ethoxy or pyrrolidonyl; CH 2 CH 2 OCH 2 CH 2 OH; or (CH 2 ) 3 (OC 2 H 4 ) n OB; n is zero, 1 or 2; B is hydrogen, C 1 to C 4 alkyl, cyclohexyl, benzyl, phenylethyl, phenyl or tolyl; R 2 and R 4 independently of one another are hydrogen or C 1 to C 4 alkyl; R 1 to R 2 together with the nitrogen are pyrrolidino, piperidino, morpholino or hexamethyleneimino; T 1 is hydrogen, chloro, bromo or methyl; T 2 is hydrogen or methyl; T 3 is hydrogen, ##STR345## or COOB 1 ; B 1 is hydrogen, C 1 to C 8 alkyl, phenyl-C 1 to C 4 -alkyl or (OC 2 H 4 ) n OB; Y is --SO 2 -- or --CO--; T 4 is hydrogen or chloro; and T 5 is hydrogen, methyl or ethyl.
