Description
Verfahren zur Herstellung eines wasserunlöslichen Azofarbstoffes zum Färben und Drucken von Zelluloseestern und -äthern. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines wasserunlös lichen Azofarbstoffes zum Färben und Druk- ken von Zelluloseestern und -äthern, dadurch gekennzeichnet,
dass man diazotiertes 4- Aminoacetophenon in essigsaurem Medium mit N-Ogäthyl-eyanäthyl-m-toluidin kuppelt.
Der so erhaltene Farbstoff färbt Acetat seide nach Zusatz eines geeigneten Dsper- giermittels in orangen Farbtönen von sehr guter Lichtechtheit und guten Nassechtheiten. Beispiel: 135 Teile 4-Aminoacetophenon werden in der üblichen Weise diazotiert und in essig saurem Medium mit 205 Teilen N-Ogäthyl- cyanäthyl-m-toluidin gekuppelt. Der ,gebil- dete Farbstoff wird abgesaugt, gewaschen und getrocknet.
Process for the production of a water-insoluble azo dye for dyeing and printing cellulose esters and ethers. The present patent relates to a process for the production of a water-insoluble azo dye for dyeing and printing cellulose esters and ethers, characterized in that
that one couples diazotized 4-aminoacetophenone in acetic acid medium with N-Ogäthyl-eyanäthyl-m-toluidine.
The dye obtained in this way dyes acetate silk, after the addition of a suitable dispersant, in orange shades of very good lightfastness and good wetfastness. Example: 135 parts of 4-aminoacetophenone are diazotized in the usual way and coupled with 205 parts of N-Ogäthyl-cyanäthyl-m-toluidine in an acetic acid medium. The dyestuff formed is filtered off with suction, washed and dried.
