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-
Die Entwicklungstemperatur beträgt 75 bis go° C, die Entwicklungsdauez ungefähr 2o Sekunden. Nachher wird gewaschen, neutralisiert und geseift.The development temperature is 75 to go ° C, the development time z about 20 seconds. Afterwards it is washed, neutralized and soaped.
Nach diesem Verfahren können sämtliche angegebenen Druckpasten nebeneinander gedrückt werden, und man erhält sowohl mit den Estersalzen von Leukoküp.enfarbstoffen als auch mit den Eisfarbenpräparaten -voll entwickelte und gleichmäßige Farbtöne.With this method, all specified printing pastes can be used side by side are pressed, and you get both with the ester salts of Leukoküp.enfarbstoffen as well as with the ice color preparations - fully developed and even color tones.
