The invention relates to a process for printing cellulose textile fibre material or cellulose/polyester mixed textile fibre material, characterised in that the fibre material is treated with a printing paste or printing ink containing a disperse dye of the formula
wherein
R1-R3 are each independently of the other hydrogen, halogen, C1-C8-alkyl or C1-C8-alkoxy,
R4 denotes hydrogen, C1-C8-alkyl or a group of the formula —SO2—NR6R7,
wherein R6 and R7 each independently of the other denote hydrogen,
C1-C8-alkyl which is unsubstituted or substituted by hydroxy, halogen, C1-C8-alkoxy or C6-C24aryl, or
C6-C30aralkyl which is unsubstituted or substituted by hydroxy, C1-C8alkyl, C1-C8alkoxy or halogen,
R5 represents hydrogen, C1-C8-alkyl or a radical of the formula
wherein R1-R4 are as defined above.
