Abstract
Paper which is opt. sized (pre- or post-sized) is coloured bluish red shades fast to light and wetting, esp. to alcohol, milk and water, with the known dyestuff of formula: the form of a salt thereof, e.g. Na,K or NH4 salt. The tinctorial prepn. which is applied to the paper, pref. directly to the paper pulp, contains per pt. dyestuff 3-11 pt. water and 0.5-3 pt. of an amino alcohol, e.g. diethanolamine. The dyestuff may also be applied from a granular prepn. contg. at most 50% of salt dissociating in water, e.g. NaCl, KCl, used in tinctorial prepns. and/or a non-hygroscopic dextrin, and the dyestuff.
Description
Gegenstand der Erfindung ist die Verwendung des Farbstoffes der Formel
EMI1.1
als Papierfarbstoff.
Der Farbstoff kann in Form von Salzen, wie z. B. Alkalimetallsalzen oder Ammoniumsalzen, verwendet werden.
Der Farbstoff der Formel (1) ist bekannt. Er dient zum Färben von Baumwolle, wobei nach den Angaben der Literatur durch Erhitzen fixiert werden muss.
Es wurde nun gefunden, dass sich der Farbstoff der For mel (I) besonders gut zur Herstellung von in der Masse gefärbtem. geleimtem oder ungeleimtem Papier eignet. Er ist besonders gut wasserlöslich.
Die erhaltenen Färbungen sind brillant, und hervorragend echt. insbesondere sehr nassfest. Die Lichtechtheit ist gut. Nach langem Belichten ändert sich die Nuance Ton in Ton.
Der Farbstoff der Formel (1) lässt sich in konzentrierte, flüssige Zubereitungen überführen, enthaltend je 1 Gewichtsteil Farbstoff, 3 bis 11 Gewichtsteile Wasser und 0,5 bis 3 Gewichtsteile eines Aminoalkohols, beispielsweise Diäthanolamin.
Diese Zubereitungen werden durch Mischen und gegebenenfalls durch kurzes Erwärmen der genannten Bestandteile hergestellt und können zusätzlich weitere Hilfsmittel, wie pH stabilisierende Hilfsmittel oder Dispergatoren, enthalten.
Die neuen Zubereitungen können als echte Lösungen oder als Dispersion, z. B. nach Verdünnen mit Wasser, zum Färben von Papier verwendet werden, wobei man das Papier in der Masse, durch Streichen oder durch Tauchen färben kann.
Die so hergestellten Zubereitungen haben den Vorteil der einfacheren Handhabung. Das lästige Stäuben beim Abwiegen von Farbstoffpulver fällt weg. Ausserdem eignen sie sich für kontinuierliche Färbeverfahren. Die Zubereitungen sind bei Raumtemperatur mehrere Monate lagerbeständig.
Sie sind nicht frostempfindlich und unempfindlich gegenüber Pilzbefall.
Die in den Beispielen genannten Teile sind Gewichtsteile; die Temperaturen sind in Celsiusgraden angegeben.
Beispiel 1
Ein Teil des Farbstoffs der Formel
EMI1.2
wird in Form eines feuchten, mineralsauren, 250/obigen Presskuchens in 8 Teilen Wasser homogen verrührt und anschliessend durch Zugabe von 0,9 Teilen Diäthanolamin, gegebenenfalls durch Erwärmen auf 60", in Lösung gebracht. Diese Zubereitung ist bei Raumtemperatur mehrere Monate haltbar.
Beispiel 2
Eine Zubereitung mit ebenfalls guter Stabilität wird erhalten. wenn man 1 Teil Farbstoff der Formel (1), in Form eines feuchten, mineralsauren, 250!eigen Presskuchens, in 3,2 Teilen 70 /Oiger Diäthanolaminlösung löst.
Beispiel 3
80 Teile eines salzhaltigen Farbstoffpulvers mit einem Gehalt von 82 /o des Farbstoffs der Formel (I) werden in einem Mischer mit 20 Teilen eines Coupagemittels, beispielsweise Dextrin, homogen vermischt. Das Färbepräparat ist in Wasser sehr gut löslich.
Vorschrift zum Färben von Papier.
In einem Holländer werden 100 Teile chemisch gebleichte Sulfitcellulose in Gegenwart von Wasser gemahlen.
Zu dieser Masse gibt man 3 Teile der Zubereitung gemäss Beispiel 2. Nach 15 Minuten erfolgt die Leimung und anschliessend dessen Fixierung.
Das auf diese Weise hergestellte Papier besitzt eine rot blauhaltige Nuance von mittlerer Intensität. Die Färbung be sitzt gute Echtheiten. Das Abwasser ist farblos.
Eine ähnlich gute Färbung erhält man, wenn man anstelle der 3 Teile der Zubereitung gemäss Beispiel 2, 0,7 Teile der Zubereitung gemäss Beispiel 3 einstreut.
The invention relates to the use of the dye of the formula
EMI1.1
as a paper dye.
The dye can be in the form of salts, such as. B. alkali metal salts or ammonium salts can be used.
The dye of the formula (1) is known. It is used to dye cotton, whereby, according to the literature, it must be fixed by heating.
It has now been found that the dye of the formula (I) is particularly good for the production of colored in the mass. size or unsized paper. It is particularly soluble in water.
The dyeings obtained are brilliant and extremely fast. especially very wet strength. The lightfastness is good. After a long exposure, the shade changes tone on tone.
The dye of the formula (1) can be converted into concentrated, liquid preparations, each containing 1 part by weight of dye, 3 to 11 parts by weight of water and 0.5 to 3 parts by weight of an amino alcohol, for example diethanolamine.
These preparations are produced by mixing and, if necessary, briefly heating the constituents mentioned and can additionally contain further auxiliaries, such as pH stabilizing auxiliaries or dispersants.
The new preparations can be used as real solutions or as a dispersion, e.g. B. after dilution with water, can be used for coloring paper, the paper can be colored in the mass, by painting or by dipping.
The preparations produced in this way have the advantage of being easier to use. The annoying dusting when weighing dye powder is eliminated. They are also suitable for continuous dyeing processes. The preparations can be stored for several months at room temperature.
They are not sensitive to frost and insensitive to fungal attack.
The parts mentioned in the examples are parts by weight; the temperatures are given in degrees Celsius.
example 1
Part of the dye of the formula
EMI1.2
is in the form of a moist, mineral acid, 250 / above press cake in 8 parts of water, stirred homogeneously and then dissolved by adding 0.9 parts of diethanolamine, if necessary by heating to 60 ". This preparation can be kept for several months at room temperature.
Example 2
A preparation with likewise good stability is obtained. if 1 part of the dye of the formula (1), in the form of a moist, mineral acidic, 250% press cake, is dissolved in 3.2 parts of 70% diethanolamine solution.
Example 3
80 parts of a salt-containing dye powder with a content of 82 / o of the dye of the formula (I) are mixed homogeneously in a mixer with 20 parts of a coupage agent, for example dextrin. The dye preparation is very soluble in water.
Rules for coloring paper.
100 parts of chemically bleached sulfite cellulose are ground in a hollander in the presence of water.
3 parts of the preparation according to Example 2 are added to this mass. After 15 minutes, the glue is applied and then it is fixed.
The paper produced in this way has a red-blue nuance of medium intensity. The dyeing has good fastness properties. The wastewater is colorless.
A similarly good color is obtained if 0.7 parts of the preparation according to Example 3 are sprinkled in instead of the 3 parts of the preparation according to Example 2.
