Description
Zusatzpatent zum <B>Hauptpatent Nr. 430 001</B> <B>Verfahren zur Herstellung</B> chromhaltiger Reaktivfarbstoffe Es wurde nun gefunden, dass man wertvolle chromhaltige Reaktivfarbstoffe erhält, indem man einen Chrom-Komplex-Farbstoff der Formel<B>l</B>
EMI0001.0010
in der A1 einen von reaktiven Gruppen freien Rest der Benzol- oder Naphthalinreihe, B einen von reaktiven Gruppen freien Rest der Benzol-,
Napthalin- oder Pyrazolreihe, wobei A1 und B den Sauerstoff -O- je in o-Stellung zur Azobindung enthalten, n eine positive ganze Zahl von höchstens 3 und A2 einen von reaktiven Gruppen freien, unsulfier- ten Rest der Benzol- oder Naphthalinreihe bedeuten,
mit einem den Rest Z einführenden Azinylierungs- mittel zu einer Verbindung der Formel II,
EMI0001.0031
in welcher Z eine Gruppe, welche mindestens einen als Anion abspaltbaren Substituenten enthält, bedeutet und Al, B, n und A2 die unter Formel I angegebene Bedeutung haben, umsetzt.
Bedeuten A1 und B einen Rest der Naphthalinreihe, so ist dieser entweder in 1-Stellung an die Azo- und in 2-Stellung an -O- gebunden oder umgekehrt.
Ist B ein Rest der Pyrazolreihe, so handelt es sich hierbei um den Rest eines 1-Aryl-, insbesondere 1-Phenyl-3-methyl-pyrazols, der in 4-Stellung an die Azogruppe und in 5-Stellung an -O- gebunden ist.
Bedeutet A2 einen von reaktiven Gruppen freien, unsulfierten Rest der Naphthalinreihe, so handelt es sich um den 2- und insbesondere den 1-Naphthylrest. Vorzugsweise bedeutet A2 einen von reaktiven Grup pen freien, unsulfierten Rest der Benzolreihe.
Die aromatischen Ringe von B und A2 können, im Rahmen der Definition, in Azofarbstoffen übliche Sub- stituenten enthalten, beispielsweise nieder Alkylgrup- pen, wie die Methyl- oder Äthylgruppe, niedere Alk- oxygruppen, wie die Methoxy- oder Äthoxygruppe, Halogene, wie Chlor oder Brom, Sulfonsäureamid-, niedere Alkylsulfonylgruppen,
ferner die Nitro- und Carboxylgruppc.
Der aromatische Ring A1 enthält vorzugsweise eine Sulfonsäuregruppe und/oder eine Nitrogruppe.
Die Ausgangsstoffe der Formel I sind bekannt oder können nach an sich bekannten Methoden hergestellt werden. So werden. die Chromkomplexe der Formel I beispielsweise durch Umsetzen eines Chrom abgeben' den Mittels mit einem Monoazofarbstoff der Formel III
EMI0002.0019
in saurem Medium und anschliessender Umsetzung mit einem Aminodisazofarbstoff der Formel IV
EMI0002.0023
erhalten,
wobei die Aminodisazofarbstoffe wiederum zum Beispiel durch Kuppeln eines diazotierten Ami- noazofarbstoffs der Formel V
EMI0002.0029
mit einer 1-Amino-8-hydroxy-3,6- bzw. -4,6-disulfon- säure in alkalischem Medium hergestellt werden.
Als den Rest Z einführende Azinylierungsmittel kommen solche in Frage, die als Anion abspaltbare Substituenten enthalten.
In erster Linie handelt es sich bei diesen Substituenten um bewegliche Halogenatome, vorzugsweise Chlor oder auch Brom oder auch Sulfon- säuregruppen, die ihre Beweglichkeit der Anwesenheit tertiärer Ringstiekstoffatome in Heterocyclen aromati schen Charakters, vorzugsweise in 6-gliedrigen Hetero- cyclen mit mindestens zwei tertiären Ringstickstoffato- men, verdanken.
Das Azinylierungsmittel bedeutet demnach z. B. ein cyclisches Imidhalogenid der Kohlensäure, insbeson dere eine mindestens zwei bewegliche Halogenatome enthaltende Triazinverbindung, z.
B. ein Chlor- oder Brom-s-triazin, welches als weitere Substituenten Halo gen, die primäre oder sekundäre Aminogruppe, eine Alkoxy-, Alkylthio-, Phenoxy- oder Phenylthiogruppe enthalten kann;
oder eine mindestens zwei bewegliche Halogenatome enthaltende, gegebenenfalls konden sierte Diazinverbindung, die gegebenenfalls an einem Ringkohlenstoff noch eine Carbonsäurehalogenid- gruppe trägt. Beispielsweise kommen in Frage:
Cya- nurchlorid, eine Tri- oder Tetrachlor- bzw. Tri-- oder Tetrabrom-pyrimidinverbindung, 2,4 Dichlor-pyrimi- din-5- oder -6-carbonsäurechlorid oder 2,3-Dichlor- chinoxalin-6-carbonsäurechlorid. Insbesondere- verwen det man als Azinylierungsmittel Tetrachlorpyrimidin.
Die Umsetzung des Aminofarbstoffs der Formel I mit dem Azinylierungsmittel erfolgt auf übliche Weise, zweckmässig in wässrigem Medium, gegebenenfalls in Gegenwart inerter, leicht entfernbarer organischer Lösungsmittel, wie niederer aliphatischer Ketone, bei spielsweise Aceton, und- vorzugsweise in Gegenwart mineralsäureabstumpfender Mittel, wie Natrium- oder Kaliumcarbonat,
Natron- oder Kalilauge, Di- oder Tri- natrium- oder Di- oder Trikaliumphosphat oder Natrium- oder Kaliumacetat. Die erhaltenen Reaktivfarbstoffe der Formel 1I können auf übliche Art und Weise, beispielsweise durch Abfiltrieren und anschliessendes Trocknen er halten werden.
Die neuen chromhaltigen 2:1-Komplexe der For mel 1I stellen dunkle Pulver dar. Sie sind in Form ihrer Alkalisalze sehr gut wasserlöslich. Sie färben Cel- lulosematerial, wie Zellwolle, Jute, Ramie, Hanf und vor allem Baumwolle, sowie auch polyamidhaltiges Fasermaterial, z.

Man färbt .diese Materialien. reit den erfindungsge- mäss erhältlichen. Farbstoffnach bekannten- Metho den.
Das Cellulosematerial imprägniert oder bedruckt man beispielsweise bei niederer Temperatur, wie bei 20-50 C, mit der gegebenenfalls verdickten Farbstoff lösung und fixiert dann den Farbstoff durch Behand lung mit säurebindenden Mitteln. Als solche kommen beispielsweise Natriumcarbonat, Kaliumcarbonat, Di- und Trinatriumphosphat, Natronlauge, bei Temperatu ren über 50 C auch Kalium- oder Natriumbicarbonat in Betracht.
Die Behandlung mit diesen Mitteln kann bei Raumtemperatur oder bei erhöhter Temperatar er folgen. Anstatt die imprägnierten Stoffe einer alka lischen Nachbehandlung zu unterwerfen, kann man das säurebindende Mittel in vielen Fällen auch schon den Imprägnierflotten oder Druckpasten beigeben und dann die Entwicklung der Färbung durch kurzes Erhit zen auf Temperaturen über 100 C bis 160 C oder durch längeres Lagern bei Raumtemperatur bewirken.
Durch die Behandlung mit säurebindenden Mitteln werden die neuen Farbstoffe chemisch an die Faser ge bunden. Die Cellulosefärbungen sind, da sich der nicht fixierte Farbstoffanteil sehr leicht auswaschen. lässt, nach dem Seifen ausgezeichnet nassecht.
Natürliche Polyamidfasern werden in heissem, schwach saurem, z.

Additional patent to main patent no. 430 001 Process for the production of chromium-containing reactive dyes It has now been found that valuable chromium-containing reactive dyes can be obtained by using a chromium complex dye of the formula <B > l </B>
EMI0001.0010
in A1 a radical of the benzene or naphthalene series free of reactive groups, B a radical of the benzene series free of reactive groups,
Napthalene or pyrazole series, where A1 and B each contain the oxygen -O- in the o-position to the azo bond, n is a positive integer not exceeding 3 and A2 is an unsulfated radical of the benzene or naphthalene series free of reactive groups,
with an azinylating agent introducing the radical Z to form a compound of the formula II,
EMI0001.0031
in which Z denotes a group which contains at least one substituent which can be split off as an anion and Al, B, n and A2 have the meaning given under formula I, is converted.
If A1 and B are a radical of the naphthalene series, this is either bonded in the 1-position to the azo and in the 2-position to -O- or vice versa.
If B is a residue of the pyrazole series, this is the residue of a 1-aryl-, in particular 1-phenyl-3-methyl-pyrazole, which is bonded to the azo group in the 4-position and to -O- in the 5-position is.
If A2 is an unsulfated radical of the naphthalene series free of reactive groups, it is the 2- and, in particular, the 1-naphthyl radical. A2 preferably denotes an unsulfated radical of the benzene series which is free of reactive groups.
The aromatic rings of B and A2 can, within the scope of the definition, contain common substituents in azo dyes, for example lower alkyl groups such as the methyl or ethyl group, lower alkoxy groups such as the methoxy or ethoxy group, halogens such as Chlorine or bromine, sulfonic acid amide, lower alkyl sulfonyl groups,
also the nitro and carboxyl groups.
The aromatic ring A1 preferably contains a sulfonic acid group and / or a nitro group.
The starting materials of the formula I are known or can be prepared by methods known per se. Be like that. the chromium complexes of the formula I, for example, by reacting a chromium release agent with a monoazo dye of the formula III
EMI0002.0019
in an acidic medium and subsequent reaction with an amino disazo dye of the formula IV
EMI0002.0023
receive,
wherein the amino disazo dyes in turn, for example by coupling a diazotized aminoazo dye of the formula V
EMI0002.0029
with a 1-amino-8-hydroxy-3,6- or -4,6-disulfonic acid in an alkaline medium.
Suitable azinylating agents which introduce the radical Z are those which contain substituents which can be eliminated as anion.
These substituents are primarily mobile halogen atoms, preferably chlorine or bromine or sulfonic acid groups, which reduce their mobility to the presence of tertiary ring nitrogen atoms in heterocycles of aromatic character, preferably in 6-membered heterocycles with at least two tertiary ring nitrogen atoms - men, owe.
The azinylating agent therefore means z. B. a cyclic imide halide of carbonic acid, in particular a triazine compound containing at least two mobile halogen atoms, e.g.
B. a chlorine or bromo-s-triazine, which can contain halogen, the primary or secondary amino group, an alkoxy, alkylthio, phenoxy or phenylthio group as further substituents;
or an optionally condensed diazine compound containing at least two mobile halogen atoms, which optionally also bears a carboxylic acid halide group on a ring carbon. For example:
Cyanuric chloride, a tri- or tetrachloro- or tri- or tetrabromopyrimidine compound, 2,4 dichloropyrimidine-5- or -6-carboxylic acid chloride or 2,3-dichloroquinoxaline-6-carboxylic acid chloride. In particular, tetrachloropyrimidine is used as the azinylating agent.
The reaction of the amino dye of the formula I with the azinylating agent is carried out in the customary manner, expediently in an aqueous medium, if appropriate in the presence of inert, easily removable organic solvents, such as lower aliphatic ketones, for example acetone, and preferably in the presence of mineral acid dumping agents such as sodium or potassium carbonate,
Sodium or potassium hydroxide solution, di- or tri-sodium or di- or tripotassium phosphate or sodium or potassium acetate. The reactive dyes of the formula 1I obtained can be kept in a customary manner, for example by filtering off and then drying.
The new chromium-containing 2: 1 complexes of the formula 1I are dark powders. In the form of their alkali salts, they are very soluble in water. They dye cellulose material such as rayon, jute, ramie, hemp and above all cotton, as well as fiber material containing polyamides, e.g.
B. natural, such as wool or silk, or synthetic, such as nylon, in brown-black to green-black shades.
These materials are colored. riding the available according to the invention. Dye by known methods.
The cellulose material is impregnated or printed, for example at a low temperature, such as at 20-50 ° C., with the optionally thickened dye solution and then the dye is fixed by treating with acid-binding agents. Sodium carbonate, potassium carbonate, di- and trisodium phosphate, sodium hydroxide solution, for example, and potassium or sodium bicarbonate at temperatures above 50 ° C. come into consideration as such.
Treatment with these agents can be carried out at room temperature or at an elevated temperature. Instead of subjecting the impregnated substances to an alkaline aftertreatment, the acid-binding agent can in many cases be added to the impregnation liquors or printing pastes and the color can then develop by briefly heating them to temperatures above 100 C to 160 C or by storing them for longer at room temperature cause.
The treatment with acid-binding agents chemically binds the new dyes to the fiber. The cellulose dyeing is because the unfixed dye is washed out very easily. leaves, excellent wetfastness after soaping.
Natural polyamide fibers are used in hot, slightly acidic, e.g. B. acetic acid bath in the presence of auxiliaries which improve the evenness of the color, such as fatty acid-alkanolamine polycondensation products, and optionally in the presence of salts such as sodium chloride or sodium sulfate.
Synthetic polyamide fibers are expediently dyed in a hot, acidic bath, then rinsed and treated in a boiling alkaline bath.
Thanks to their good build-up capacity, the dyes obtainable according to the invention result in very deep, genuine colorations and. are therefore particularly suitable for creating rich black tones:
In the following examples, unless expressly stated otherwise, parts are parts by weight and the temperatures are given in degrees Celsius. Parts by weight are related to parts by volume as grams are to cubic centimeters. <I> Example 1 </I>
