Abstract

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

R 1 -R 3 are each independently of the other hydrogen, halogen, C 1 -C 8 -alkyl or C 1 -C 8 -alkoxy,

R 4 denotes hydrogen, C 1 -C 8 -alkyl or a group of the formula —SO 2 —NR 6 R 7 ,

wherein R 6 and R 7 each independently of the other denote hydrogen,

C 1 -C 8 -alkyl which is unsubstituted or substituted by hydroxy, halogen, C 1 -C 8 -alkoxy or C 6 -C 24 aryl, or

C 6 -C 30 aralkyl which is unsubstituted or substituted by hydroxy, C 1 -C 8 alkyl, C 1 -C 8 alkoxy or halogen,

R 5 represents hydrogen, C 1 -C 8 -alkyl or a radical of the formula

wherein R 1 -R 4 are as defined above.

First claim

The invention claimed is:

1. 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
R 1 -R 3 in formulas (1)-(4) are a C 1 -C 8 alkyl,
R 4 denotes hydrogen, C 1 -C 8 alkyl or a group of the formula —SO 2 —NR 6 R 7 ,
wherein R 6 and R 7 each independently of the other denote hydrogen,
C 1 -C 8 alkyl which is unsubstituted or substituted by hydroxy, halogen, C 1 -C 8 alkoxy or C 6 -C 24 aryl, or
C 6 -C 30 aralkyl which is unsubstituted or substituted by hydroxy, C 1 -C 8 alkyl, C 1 -C 8 alkoxy or halogen,
R 5 represents hydrogen, C 1 -C 8 alkyl or a radical of the formula

wherein R 4 is as defined above and R 1 -R 3 in formula (5) are each independently of the other hydrogen, halogen, C 1 -C 8 alkyl or C 1 -C 8 alkoxy.

2. The process according to claim 1 wherein R 4 in formulas (1)-(4) denotes a radical of the formula —SO 2 —NR 6 R 7 ,
wherein R 4 in formula (5) denotes hydrogen, C 1 -C 8 alkyl or a group of the formula —SO 2 —NR 6 R 7, and
R 6 and R 7 in R 4 of formulas (1)-(5) are as defined in claim 1 .

3. The process according to claim 1 , characterised in that the fibre material is treated with a printing paste or printing ink containing a disperse dye of the formula (1), (2) or (3), wherein R 5 is a radical of the formula (5) and wherein R 1 -R 3 in formula (5) are C 1 -C 8 alkyl.

4. The process according to claim 3 , wherein R 4 in formula (5) is —SO 2 —NR 6 R 7.

5. The process according to claim 1 , characterised in that the fibre material is treated with a printing paste or printing ink containing a disperse dye of the formula (1), wherein
R 1 -R 3 are C 1 -C 8 alkyl,
R 4 is hydrogen or a radical of the formula —SO 2 —NR 6 R 7 , wherein R 6 is hydrogen and R 7 is 3-methoxypropyl, and
R 5 is a radical of the formula (5), wherein R 1 -R 3 are C 1 -C 8 alkyl and R 4 is hydrogen or a radical of the formula —SO 2 —NR 6 R 7 , wherein R 6 is hydrogen and R 7 is 3-methoxypropyl.

6. The process of claim 1 , characterised in that the fibre material is treated with a printing paste according to the screen printing method.

7. The process of claim 1 , characterised in that the fibre material is treated with a printing ink according to the inkjet printing method.

8. The process according to claim 7 , wherein the fibre material in a first step is treated with a water-soluble organic solvent having a boiling point >150° C. and subsequently is printed with an aqueous ink comprising at least one disperse dye of the formula (1), (2), (3) or (4).

9. The process according to claim 8 , characterised in that a drying step is applied after the treatment with the water-soluble organic solvent.
