摘要：
Dye formulations for dyeing and printing cellulose and cellulosic textile material which in addition to conventional components contain a dye of the general formula (I): ##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.
