Dye formulations for dyeing or printing cellulose or cellulosic fibrous material which in addition to the usual dispersing agents, water retention agents, disinfectants and water contain dyes devoid of sulfonic acid groups and of the general formula: ##STR1## in which A is an anthraquinonyl, anthrapyrimidone or anthrapyrimidine radical which may bear substituents; X is hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical; B is hydrogen or an aliphatic radical; B.sup.1 is an aliphatic, araliphatic or aromatic radical or the group ##STR2## is a five-membered, six-membered or seven-membered heterocyclic ring; and n is 1 or 2. Dyeings and prints having very good fastness properties and particularly very good fastness to wet treatments and crocking are obtained on cellulose. The dyes contained in the formulations are fixed on swollen cellulosic fibers by heating.

Triazinyl-anthraquinone dye formulations for cellulose or cellulosic

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;

Uniformly dyed water-swellable cellulosic fibers

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 ; and R.sup.1 --n--r.sup.2 and R.sup.3 --N--R.sup.4 independently of one another are saturated heterocyclic radicals.

Azo dyes having a 3-cyano- or 3-carbamoyl-2,6-diamino-pyridine coupling

Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers in the swollen state with a dye of the formula ##STR1## in which D is the radical of a diazo component;

Dye formulations for transfer printing which in addition to conventional ingredients contain dyes of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are hydrogen, hydroxy, chloro, bromo or alkylamino substituents, one of R.sup.1 to R.sup.3 being different from hydrogen. The dyes are distinguished by a comparatively very low transfer temperature.

Transfer dyes

A print paste for printing textiles of polyester, cellulose acetate, cellulose triacetate and mixtures of the same with other fibers which is based on a disperse dye, thickener, ethanolamide of a carboxylic acid and water and which is characterized by a content of at least one phenol which has been oxyethylated twice to six times. The paste yields prints having excellent color strength and levelness.
