Description

Verfahren zum Entwickeln von Drucken mit Estersalzen von Leukoküpenfarbstoffen neben Drucken mit Eisfarbenpräparaten, die durch Säureeinwirkung entwickelt werden und schwerlösliche Metalloxyde enthalten Die gemeinsame nasse Entwicklung von Drucken mit Estersalzen von Leukoküpenfarbstoffen (Indig osolen) und Drucken mit Eisfarbenpräparaten, die durch Säureeinwirkung entwickelt werden (Rapidogenfarbstoffen), war bisher in befriedigender Weise nicht durchführbar, da es nicht möglich war, eine zugleich für beide Farbstoffarten geeignete Säurekonzentration des Entwicklungsbades zu finden.Process for developing prints with ester salts of leuco vat dyes in addition to prints with ice color preparations that are developed through the action of acids and sparingly soluble metal oxides contain The common wet development of prints with ester salts of leuco vat dyes (indigo sols) and prints with ice color preparations, which are developed by the action of acids (rapidogen dyes), was previously in satisfactorily not feasible since it was not possible to do one at the same time to find a suitable acid concentration in the developing bath for both types of dye.

Die Eisfarbenpräparatewerden nämlich am besten in einem Bade, das Ameisen- und Essigsäure enthält, entwickelt. Diese organischen Säuren genügen zwar auch zur Entwicklung mancher Estersalze von Leuko= küpenfarbstoffen. Für einen Teil der Estersalze ist dagegen mineralsaure Reaktion. des Entwicklungsbades zur Spaltung unumgänglich nötig, wodurch die Farbstoffbildung aus den Eisfarb.enpräparaten., jedoch verzögert oder verhindert wird. Weiter ist die genaue Einbaltung einer bestimmten Temperatur und einer bestimmten Säurekonzentration des Entwicklungsbades notwendig, um eine gleichmäßig gute Entwicklung der Drucke zu erzielen, ein Erfordernis, welches im Druckereibetriebe nicht immer gut erfüllbar ist.The ice color preparations are best made in a bath Contains formic and acetic acid. These organic acids are sufficient also for the development of some ester salts of leuco vat dyes. For one part the ester salt, on the other hand, is a mineral acid reaction. the development bath for cleavage inevitably necessary, whereby the dye formation from the ice color preparations., however, it is delayed or prevented. Next is the exact incorporation of a certain one Temperature and a certain acid concentration of the developing bath necessary, in order to achieve a uniformly good development of the prints, a requirement which is not always easy to fulfill in the printing company.

Es wurde nun gefunden, daß Drucke mit den Eisfarbenpräparaten neben Drucken mit Estersalzen von LeukoIzüpenfarbstoffen auch in mineralsaurem Bade entwickelt werden können, wenn man der Eisfarbendruckpasite in Wasser schwerlösliche Metalloxyde oder hydroxyde, wie Zinkoxyd oder Aluminiumhydroxyd, zusetzt. Ein genaues Einhalben der Entwicklungstemperatur ist dann nicht mehr nötig. Man hat einen Spielraum von 15 bis 2o° C.It has now been found that prints with the ice color preparations next to Printing with ester salts of leucoIcine dyes also developed in mineral acid baths can be, if one of the ice color printing pasite in water sparingly soluble metal oxides or hydroxides, such as zinc oxide or aluminum hydroxide, are added. An exact half the development temperature is then no longer necessary. You have a margin of 15 to 20 ° C.

Es ist zwar bekannt, Eisfarben neben,Estersalzfärbungen ,auf ähnliche Weise zu entwickeln. Bei diesien bekannten Verfahren werden Eisfarbenpräparate verwendet, die ebenfalls in Wasser schwerlösliche Metalloxyde .enthalten. Die Entwicklungsbäder enthalten neben organischen Säuren dissozierhare, Mineralsäure ahsp.albende Salze, und die Entwicklung der Färbungen wird durch Hitze-,einwirkun,g auf einer geheizten Trockentroimmel oder in einer geheizten Kammer herbeigeführt. Bei dem vorliegenden Verfahren werden dagegen Entwicklungsbäder verwendet, die neben organischen Säuren freie Mine- ralsäure enthalten, und die Entwicklung C$@,@' folgt in diesen Bädern bei ungefähr 75 W' go° C. Diese Entwicklung ist milder als dl Entwicklung bei den bekannten Verfahren;' so daß die Gefahr einer Faserschädigung durch die Mineralsäure, die bei den bekannten Verfahren nicht von der Hand zuweisen ist, ausgeschaltet wird. Außerdem ist das vorliegende Verfahren in der Durchführung ach as Verfahren T. wird durch die folgenden Beispieleerläutert: Man bedruckt weißes Baumwollgewebe mit Druckpasten, die nach folgender Vorschrift hergestellt wurden: r. 2. .. q..

In these known processes, ice color preparations are used which also contain metal oxides that are sparingly soluble in water. In addition to organic acids, the development baths contain dissociative, mineral acid-reducing salts, and the development of the color is brought about by heat, action on a heated drying oven or in a heated chamber. In the present process, on the other hand, development baths are used which, in addition to organic acids, contain free minerals. Containing ralic acid, and developing C $ @, @ ' follows in these baths at about 75 W ' go ° C.
