Description

Verfahren zur Herstellung blauer Färbungen auf Celluloseestern oder -äthern Gegenstand des Patents 509 401 ist ein Verfahren zur Herstellung überfärbeechter violetter Färbungen auf Celluloseestern und -äthern, das darin besteht, daß man diazotierte 4-.,#-mino-6-acylaminortsorcindiall<yl-oder -diaryläther oder ihre Substitutionsprodukte auf der zu färbenden Substanz mit 2,3-Oxynaphthoesäure oder ihren 'Aryliden kuppelt.Process for the production of blue dyeings on cellulose esters or ethers The object of the patent 509 401 is a process for the production of violet dyeings on cellulose esters and ethers which are fast to over-dyeing. or -diaryl ethers or their substitution products on the substance to be colored with 2,3-oxynaphthoic acid or their 'arylids.

Bei weiterer Ausarbeitung des Erfindungsgedankens obiger Patentschrift ist nun gefunden worden, daß man zu klaren blauen Farbtönen auf Celluloseestern und -äthern kommt, wenn man diazotierte 2-Amino-5-acvlaminohvdrocbinondiallkyl-, -aralkyl- oder -aryiäther od'er ihre Substitutionsprodukte auf der zu färbenden Substanz mit 2, 3-OxY-naphthoesäure oder ihren Aryliden kuppelt. Die Färbungen zeichnen sich durch vorzügliche Wasch-, Wasser-, Überfärbe- und Chlorechtheit aus, besitzen eine praktisch genügende Lichtechtheit und sind ätzbar. B e i s p i e 1 e i. i kg Acetatseide wird in ein Färbebad von 4o 1, in welchem io g 2,-Amino-5-benzoylaminohydrochinond#imethyläther mit der iofachen Menge Türkischrotöl gelöst sind, gebracht. (Y Es wird langsam erwärmt und '/, Stunden bei 7o bis 75' C umgezogen. Darauf wird gespült, wie üblich in einem frischen Bade diazotiert und in einem weiteren Bade mit 2, 3-Oxynaphthoesätire i Stunde bei 5o' C schwach essigsauer entwickelt.In further elaboration of the inventive concept of the above patent, it has now been found that clear blue tones are obtained on cellulose esters and ethers if diazotized 2-amino-5-acvlaminohvdrocbinondialkyl, aralkyl or aryl ethers or their substitution products are used to be colored substance with 2, 3-OxY-naphthoic acid or its arylids. The dyeings are characterized by excellent fastness to washing, water, over-dyeing and chlorine, have practically sufficient lightfastness and are etchable. Eg p ie 1 e i. 1 kg of acetate silk is placed in a dyebath of 40 1, in which 10 g of 2, -amino-5-benzoylaminohydroquinone / methyl ether are dissolved with 10 times the amount of Turkish red oil. (Y It is warmed up slowly and changed for 1/2 hours at 70 to 75 ° C. It is then rinsed, diazotized as usual in a fresh bath and developed in a further bath with 2,3-Oxynaphthoesätire for 1 hour at 50 ° C. weakly acetic acid .

Man erhält auf diese Weise ein kräftiges, klares Blau.In this way, a strong, clear blue is obtained.

2. 1 kg Acetatseide wird in ein Färbebad von 4o 1, in welchem 20 g 2-Amino-5-P-clilorbenzovlainiii!ohvdrochinond!iäthyl-iither mit der i ofac#en Menge- Tfirlzischrotöl gelöst sind, gebracht. Es wird langsam erwärmt und "/, Stunden bei 7o bis 75' C umgezogen. Darauf wird gespült, wie Üblich in einem frischen Bade diazotiert und in einem weiteren Bade mit 2, 3-Oxynaphthoesäure i Stunde bei 50' C schwach essigsauer eniwickelt.2. 1 kg of acetate silk is placed in a dyebath of 40 l , in which 20 g of 2-amino-5-P-chlorobenzovlainiii / ohvdroquinone / iäthyl-iither are dissolved with the iofac # en amount of Tfirlzischrotöl. It is slowly warmed up and removed for 1/2 hours at 70 ° to 75 ° C. It is then rinsed, diazotized as usual in a fresh bath and wrapped in weak acetic acid in a further bath with 2,3-oxynaphthoic acid for 1 hour at 50 ° C.

Man erhält hierbei ebenfalls ein kräftiges Blau.A strong blue is also obtained here.

3. 1 kg Acetatseide wird in einem Färbebad voll 30 1, in welchem 5 g 2-Amino-5-bellzoylaminohydrochino,ndimethyläther unter Zusatz von Salzsäure gelöst sind, unter langsamer Temperatursteigerung si, Stunden bei 70 bis 75' behandelt. Nach 1/,stündigem. Umziehen werden hierbei zweckmäßig 5117, Natriumacetat zugegeben. Darauf wird gespült, wie üblich in einem frischen Bade diazotiert und in einem weiteren Bade mit 5 "/" 2, 3-Oxynap#htho#esäureanilid in neutraler Suspension i Stunde bei 65 bis 70' entwickelt. Man erhält eine kräftige violette Färbung. 4. Statt der in BeisPiel 3 genannten Base nimmt man hier i o g 2-Amino- 5-belizoylaminohydrocliinondiäthyläther und färbt wie vorher. Man erhält eine kräftige, blauviolette Färbung. 3. 1 kg of acetate silk is treated in a dyebath full of 30 liters, in which 5 g of 2-amino-5-bellzoylaminohydrochino-dimethyl ether are dissolved with the addition of hydrochloric acid, while slowly increasing the temperature for 70 to 75 hours. After 1 /, hour. It is advisable to add 5117 sodium acetate during this process. It is then rinsed, diazotized as usual in a fresh bath and developed in a further bath with 5 "/" 2, 3-Oxynap # htho # esäureanilid in neutral suspension for 1 hour at 65 to 70 ' . A strong purple color is obtained. 4. Instead of the base mentioned in Example 3 , take 10 g of 2-amino-5-belizoylaminohydroclinone diethyl ether and dye as before. A strong, blue-violet color is obtained.
