Description

Verfahren zur Herstellung von Azofarbstoffen auf der Faser Es wurde gefunden, daß die Kondensationsprodukte von primären Aminen und Ketonen sich vorzüglich für die Zwecke der Entwicklungsfarben eignen. Die, wie üblich, durch Behandeln der mit Oxynaphthoesäurearyliden präparierten Ware mit den Diazoniumverbindungen der genannten Kondensationsprodukte hergestellten Färbungen zeigen vor den bereits bekannten den Vorteil einer sehr guten Beuchechtheit neben sehr guter Koch- und Chlorechtheit und einer bemerkenswerten Lichtechtheit.Process for the production of azo dyes on the fiber It was made found that the condensation products of primary amines and ketones are excellent suitable for the purpose of developing colors. Which, as usual, by handling the with Oxynaphthoesäurearyliden prepared goods with the diazonium compounds of The above-mentioned condensation products show dyeings before those already known the advantage of a very good touch fastness in addition to very good boiling and chlorine fastness and a remarkable lightfastness.

Beispiel i 50 g Baumwollstrang werden mit 5 g 2, 3-Oxynaphthoesäure-2'-methoxyanilid, wie üblich, in 1 1 Wasser gelöst, % Stunde behandelt, abgequetscht und in 1 1 einer Lösung entwickelt, welche die Tetrazoverbindung aus 1,35 g des Kondensationsproduktes aus Anilin und Cyclohexanon enthält. Man erhält ein klares, volles Rot von hervorragender Koch- und Chlorechtheit und sehr guter Beuchechtheit.Example i 50 g of cotton hank are dissolved with 5 g of 2,3-oxynaphthoic acid-2'-methoxyanilide, as usual, in 1 l of water, treated for 1 hour, squeezed off and developed in 1 l of a solution which contains the tetrazo compound from 1.35 g of the condensation product of aniline and cyclohexanone contains. A clear, full red of excellent boiling and chlorine fastness and very good touch fastness is obtained.

Ähnliche Töne und gleich gute Echtheiten erhält man bei Verwendung von 2, 3-Oxynaphthoesäure-2'-naphthalid, -4'-methoxyanilid, -1'-naphthalid us-,v.Similar shades and equally good fastness properties are obtained when used of 2,3-oxynaphthoic acid-2'-naphthalide, -4'-methoxyanilide, -1'-naphthalide us-, v.

Beispiel e 5o g Baumwollgarn werden mit 49 2, 3-Oxynaphthoesäure-2', 5'-dimethoxyanilid, wie üblich, in 1 1 Wasser gelöst, l/, Stunde behandelt, abgequetscht und in 11 einer Lösung entwickelt, welche die Tetrazoverbindung aus 1,45 g des Kondensationsproduktes aus Anilin und Acetophenon enthält. Man erhält ein klares Scharlachrot von hervorragender Kochechtheit, sehr guter Chlor- und Beuchechtheit.Example e 50 g of cotton yarn are dissolved with 49 2,3-oxynaphthoic acid-2 ', 5'-dimethoxyanilide, as usual, in 1 liter of water, treated for an hour, squeezed off and developed in a solution which contains the tetrazo compound from 1 , 45 g of the condensation product of aniline and acetophenone contains. A clear scarlet red of excellent boiling fastness, very good fastness to chlorine and beech is obtained.

Beispiel 3 50 g Baumwollgarn werden mit 1,5 g 2, 3-Oxynaphthoesäure-2'-naphthalid, wie üblich, in i 1 Wasser gelöst, % Stunde behandelt, abgequetscht und in 11 einer Lösung entwickelt, welche die Tetrazoverbindung aus i,i5 g des Kondensationsproduktes aus Anilin und Aceton enthält. Man erhält ein lebhaftes Scharlachrot von hervorragender Kochechtheit und sehr guter Chlor- und Beuchechtheit.Example 3 50 g of cotton yarn are dissolved in 1.5 g of 2,3-oxynaphthoic acid-2'-naphthalide, as usual, in 1 1 of water, treated for 1 hour, squeezed off and developed in 1 1 of a solution which contains the tetrazo compound from i, i5 g of the condensation product from aniline and acetone contains. A vivid scarlet red of excellent boiling fastness and very good fastness to chlorine and beech is obtained.
