ABSTRACT:
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.
