DIRECT PURPOSES FOR FIBERS OF NATURAL ORIGIN AND SYNTHETIC FIBERS |
| abstract |
A new process is disclosed for preparing N-(2-nitro-4-aminophenyl)-aminoalkane sulfonic acids having formula (I), in which R<1>, R<2> and R<3> stand for hydrogen, alkyl groups with 1 to 4 C atoms or hydroxyalkyl groups with 2 to 4 C atoms and n is an integer from 1 to 6. Also disclosed are the salts of these compounds and their use as colouring agents for natural and synthetic fibres. They are preferably used for dyeing keratin-containing fibres, above all human hair. |
