Description
Verfahren zum Färben von Celluloseestern oder -äthern ' oder ihren Umwandlungsprodukten Gegenstand des Patents 5 z 5o29 ist ein Verfahren zum Färben von Celluloseestern oder -äthern oder ihren Umwandlungsprodukten mit Naphthalsäurederivaten vom allgemeinen Typ wobei X Wasserstoff, Alkyl, Aryl oder Aralkyl bedeutet. Man erhält Färbungen z. B. auf Acetatseide in kräftigen gelben Farbtönen, die durch ihren Grünstich alle bisher im Handel befindlichen Acetatseidefarbstoffe übertreffen und eine außergewöhnliche Klarheit besitzen. Es wurde nun weiter gefunden, daß man gleiche Färbungen erhält, wenn man zum Färben die. Sulfaminsäuren der allgemeinen Formel: wobei X Wasserstoff, Alkyl, Aryl oder Aralkyl bedeutet, anwendet.Process for dyeing cellulose esters or ethers or their conversion products The subject of patent 5 z 5o29 is a process for dyeing cellulose esters or ethers or their conversion products with naphthalic acid derivatives of the general type where X is hydrogen, alkyl, aryl or aralkyl. One obtains colorations such. B. on acetate silk in strong yellow shades, which surpass all the acetate silk dyes currently on the market due to their green tint and have an exceptional clarity. It has now been found that the same dyeings are obtained if the dyeing is used. Sulphamic acids of the general formula: where X is hydrogen, alkyl, aryl or aralkyl, uses.
Diese Sulfaminsäuren können dargestellt werden durch Kondensation der 4.-Sulfaminsäure von Naphthalsäureanhydrid oder deren Salzen mit Ammoniak, aliphatischen und aromatischen Aminen oder durch überführen der im Hauptpatent beschriebenen Aminonaphthalsäurederivate in die entsprechenden Sulfaminsäuren.These sulfamic acids can be represented by condensation the 4th sulfamic acid of naphthalic anhydride or its salts with ammonia, aliphatic and aromatic amines or by converting those described in the main patent Aminonaphthalic acid derivatives into the corresponding sulfamic acids.
Beispiele i. i kg Acetatseide wird in einem Färbebad von 3o bis 40 1, in welchem a 5 g des Farbstoffes gelöst sind, unter Zusatz von 4oo7o Glaubersalz und 30,!o Schwefelsäure 3/.. Stunden bei o bis 75'C gefärbt. Man erhält ein gr ünstichiges Gelb von hervorragender Klarheit und stark grünlicher Fluoreszenz.Examples i. i kg of acetate silk is in a dye bath of 3o to 40 l, in which a 5 g of the dye are dissolved, colored with the addition of 4oo7o Glauber's salt and 30,! o sulfuric acid for 3 / .. hours at 0 to 75 ° C. A greenish yellow of excellent clarity and strongly greenish fluorescence is obtained.
z. Nimmt man an Stelle des Farbstoffes des Beispiels i die äquivalente Menge des Farbstoffes so erhält man .ebenfalls eine grünstichiggelbe Färbung von ähnlichen Eigenschaften. Bei Verwendung von q.-Sulfaminoi . 8-naphthal-z', 4'-dimethylphenylimid: erhält man ebenfalls eine hervorragend klare, stark grünstichige Färbung.z. If the equivalent amount of the dye is used instead of the dye of Example i this also gives a greenish yellow color with similar properties. When using q.-sulfaminoi. 8-naphthal-z ', 4'-dimethylphenylimide: an outstandingly clear, strongly greenish coloration is also obtained.
