Description

Verfahren zum Färben von Acotylcellulose. Es wurde gefunden, daß die Azofarbstoffe, die man erhält, wenn man die :2 - 8-Naphthylamin- bzw. 2 - 8-Naphtholsulfosäure oder ihre Derivate mit den Diazoverbindungen von Aminen, die keine Sulfogruppen enthalten, kombiniert, zum Färben von Acetatseide geeignet sind.Method for coloring acotyl cellulose. It has been found that the azo dyes which are obtained when the 2 - contain from 8-Naphtholsulfosäure or their derivatives with diazo compounds of amines which no sulfo groups, combined, suitable for the dyeing of acetate rayon - 8-naphthylamine and 2 are.

Die Farbstoffe ziehen außerordentlich kräftig auf Acetatseide auf und besitzen vorzügliche Echtheitseigenschaften.The dyes are extremely strong on acetate silk and have excellent fastness properties.

Beispiel i.Example i.

153 Teile Aminohydrochinondimethyläther werden diazotiert und mit 223 Teilen 2 - 8-Naphthylaminsulfosäure gekuppelt. Der Farbstoff wird in der üblichen Weise aufgearbeitet. Er färbt Acetatseide in gelben Tönen an. Beispiel 2.153 parts Aminohydrochinondimethyläther are diazotized with 223 parts of 2 - 8-coupled Naphthylaminsulfosäure. The dye is worked up in the usual way. He dyes acetate silk in yellow tones. Example 2.

168 Teile p-Nitro-o-anisidin werden diazotiert und mit 299 Teilen Phenyl-2 - 8-naphthylaminsulfosäure gekuppelt. Der Farbstoff wird in der üblichen Weise aufgearbeitet. Er färbt Acetatseide in ziegelroten Tönen an. Beispiel 3. 168 parts of p-nitro-o-anisidine are diazotized with 299 parts of phenyl 2 - 8-naphthylaminsulfosäure coupled. The dye is worked up in the usual way. He dyes acetate silk in brick-red tones. Example 3.

127,5 Teile o-Chloranilin werden diazotiert und mit :299 Teilen Phenyl-# - 8-naphthviaminsulfosäure gekuppelt. Der Farbstoff wird in üblicher Weise aufgearbeitet. Er färbt Acetatseide in rötlichgelben Tönen an.127.5 parts of o-chloroaniline are diazotized and coupled with: 299 parts of phenyl- # - 8-naphthviaminesulfonic acid. The dye is worked up in the usual way. He dyes acetate silk in reddish yellow tones.

Beispiel 4.Example 4.

153 Teile Aminohydrochinondirnethyläther werden diazotiert und mit :22,4 Teilen :2 - 8-Naphtholsulfosäure gekuppelt. Der Farbstoff färbt Acetatseide in Rosatönen an.153 parts Aminohydrochinondirnethyläther are diazotized with 22.4 parts of 2 - 8-coupled Naphtholsulfosäure. The dye stains acetate silk in shades of pink.
