Claims
- 1. A process for the coloration of cellulose diacetate, cellulose triacetate, polyurethane, polyolefine, polyamide or aromatic polyester fibers which comprises applying to said fibers a dyestuff of the general formula: ##STR13## in which R.sub.1 represents hydrogen, halogen, nitro, alkyl or alkoxy, and R.sub.2 represents hydrogen, halogen or cyano.
- 2. The process according to claim 1 in which the alkyl or alkoxy group of the dyestuff contains from one to four carbon atoms.
- 3. The process according to claim 1 in which R.sub.1 in said dyestuff is methyl, methoxy or ethoxy.
- 4. The process according to claim 1 in which the halogen in said dyestuff is chlorine or bromine.
- 5. The process according to claim 4 in which the alkyl or alkoxy group of the dyestuff contains from one to four carbon atoms.
- 6. The process according to claim 4 in which R.sub.1 in said dyestuff is methyl, methoxy or ethoxy.
- 7. The process according to claim 1 in which the dyestuff corresponds to the formula: ##STR14##
- 8. Cellulose diacetate, cellulose triacetate, polyurethane, polyolefine, polyamide or aromatic polyester fibers colored by means of a dyestuff of the general formula: ##STR15## in which R.sub.1 represents hydrogen, halogen, nitro, alkyl or alkoxy, and R.sub.2 represents hydrogen, halogen or cyano.
- 9. The colored fibers according to claim 8 in which the alkyl or alkoxy group of the dyestuff contains from one to four carbon atoms.
- 10. The colored fibers according to claim 8 in which R.sub.1 in said dyestuff is methyl, methoxy or ethoxy.
- 11. The colored fibers according to claim 8 in which the halogen in said dyestuff is chlorine or bromine.
- 12. The colored fibers according to claim 11 in which the alkyl or alkoxy group of the dyestuff contains from one to four carbon atoms.
- 13. The colored fibers according to claim 11 in which the halogen in said dyestuff is chlorine or bromine.
- 14. The colored fibers according to claim 4 in which the dyestuff corresponds to the formula: ##STR16##
