Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers in the swollen state with a dye of the formula ##STR1## in which one R is R 1 , OR 1 , SR 1 or ##STR2## the other R is ##STR3## R 1 and R 2 independently of one another are hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical, ##STR4## may also be a saturated heterocyclic radical, and D is the radical of a diazo component. The dyed fibers exhibit very good fastness properties. |
