    • Uniformly dyed water-swellable cellulosic fibers which are fast to washing, dry-cleaning, sublimation and light and have been produced by contacting water-swellable cellulose fibers sequentially 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 ##STR1## in which D is the radical of a diazo component;R is hydrogen, C.sub.1 to C.sub.7 alkyl, phenyl or phenyl bearing methyl as a substituent;X is cyano, carbamoyl or substituted carbamoyl;R.sup.1 is hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical;R.sup.2 is hydrogen or an aliphatic, cycloaliphatic or araliphatic radical;R.sup.3 and R.sup.4 independently of one another have the same meanings as R.sup.1 and R.sup.2 ; andR.sup.1 --n--r.sup.2 and R.sup.3 --N--R.sup.4 independently of one another are saturated heterocyclic radicals.
    • 均匀染色的水溶胀性纤维素纤维,其快速洗涤,干洗,升华和光亮,并且是通过使水溶胀性纤维素纤维顺序或顺序地与水,乙二醇或其衍生物接触而产生的,而纤维仍然 溶胀,基本上不溶于式(I)的水不溶性染料,其中D是重氮组分的基团; R为氢,C1至C7烷基,苯基或含苯基的甲基作为取代基; X是氰基,氨基甲酰基或取代的氨基甲酰基; R1是氢或脂族,脂环族,芳脂族或芳族基团; R2是氢或脂族,脂环族或芳脂族基; R 3和R 4彼此独立地具有与R 1和R 2相同的含义; 并且R 1 -N-R 2和R 3 -N-R 4彼此独立地是饱和杂环基。
