Description
Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zur Herstellung von hektrographischen oder lithographischen Druckformen, bei dem die Ablichtung einer Vorlage auf eine vorzugsweise durchleuchtungsfähige Folie mit einer lichtempfindlichen Kolloid-Silberhalogenid-Schicht, z. B. Gelatine-Sülberhalogenid-Schicht, erfolgt und bei dem durch gerbende Entwicklung die Kolloidschicht der Folie an den bildfreien Stellen gehärtet wird, insbesondere nach Zusatzpatentanmeldung R 29 441 VI b/15 b. ι οThe invention relates to a further embodiment of the method for producing hectographic or lithographic printing forms, in which the copying of an original onto a preferably translucent Foil with a photosensitive colloidal silver halide layer, e.g. B. Gelatin-Sülberhalogenid-Layer, takes place and in which by tanning development the colloid layer of the film on the non-image Places is hardened, in particular according to additional patent application R 29 441 VI b / 15 b. ι ο
Bei dem in der Zusatzpatentanmeldung R 29 441 VIb/15 b vorgeschlagenen Verfahren waren die weichmachenden Substanzen, wie z. B. Natriumsalicylat, in der Benetzungsflüssigkeit für die Folie enthalten. Dies hatte zur Folge, daß die nicht gegerbten Gelatineteile bereits während der Benetzung schon auf ihren gewünschten Weichheitsgrad erweicht wurden. Die Erfindung setzt sich zum Ziel, den gewünschten Weichheitsgrad erst später herzustellen.In the method proposed in the additional patent application R 29 441 VIb / 15 b, the softening substances, such as. B. sodium salicylate, contained in the wetting liquid for the film. This had the consequence that the gelatin parts not tanned already during the wetting softened to their desired degree of softness. The invention aims to achieve the desired Only establish the degree of softness later.
Erfindungsgemäß wird gegen die mit einer Lösung aus alkalischen Entwicklersubstanzen benetzte Folie ein Abhebeblatt gegebenenfalls unter Erwärmung der Lösung gepreßt, welches sowohl gerbende Entwicklersubstanzen oder alkalisch reagierende Substanzen als auch eine Gelatine weichmachende Substanz als Schicht, Einarbeitung oder Tränkung enthält, und bei der gerbenden Entwicklung der Kolloidschicht erst der gewünschte Weichheitsgrad der ungehärteten Stellen der Kolloidschicht während des Kontaktes mit dem Abhebeblatt erzielt.According to the invention, the film wetted with a solution of alkaline developer substances is used a lift-off sheet, optionally pressed while heating the solution, which both tanning developer substances or alkaline reacting substances as well as a gelatin softening substance as Layer, incorporation or impregnation contains, and only during the tanning development of the colloid layer the desired degree of softness of the uncured areas of the colloid layer during contact with the lift-off sheet achieved.
Vorzugsweise werden als weichmachende Substanzen eine Schicht, Einarbeitung oder Tränkung aus Natriumsalicylat, Salizylsäure, Harnstoff oder äquivalente Substanzen neben den gerbenden Entwicklersubstanzen oder alkalisch reagierenden Substanzen verwendet.A layer, incorporation or impregnation are preferably used as plasticizing substances Sodium salicylate, salicylic acid, urea or equivalent substances in addition to the tanning developer substances or alkaline reacting substances are used.
In der weiteren Ausführung des Verfahrens sind auf einem Blatt Papier, Kunststoff od. dgl. eine Schicht aus gerbenden Entwicklersubstanzen oder einer alkalisch reagierenden Substanz und einer Gelatine weichmachenden Substanz in stabilisierter Form als Schicht aufgebracht, mit diesen Stoffen getränkt oder diese Stoffe eingearbeitet.In the further execution of the method od on a sheet of paper, plastic Layer of tanning developer substances or an alkaline substance and a gelatin Softening substance in a stabilized form applied as a layer with these substances soaked or incorporated these substances.
Die Herstellung des gewünschten Weichheitsgrades der nicht gegerbten Gelatine erst beim Kontakt mit dem Abhebeblatt — also praktisch nach bzw. beim Verlassen des Entwicklungsgerätes — bietet den großen Vorteil, daß die gegerbten ungehärteten Stellen der Gelatineschicht bzw. Kolloidschicht nicht an den Führungen des Entwicklungsgerätes beschädigt werden können, sondern die volle Menge der ungehärteten Gelatine unbeschädigt zum späteren Kon-Verfahren zur HerstellungThe production of the desired degree of softness of the untanned gelatine only upon contact with the lift-off sheet - practically after or when leaving the developing device the great advantage that the tanned, unhardened areas of the gelatin layer or colloid layer are not on the guides of the processor can be damaged, but the full amount of the uncured Gelatine undamaged for the later Kon process for production

takt mit dem Schichtübertragungsblatt erhalten bleibt. Außerdem wird vermieden, daß sich weiche ungehärtete Gelatineteile mit der Zeit an den Führungen der Folie im Behandlungsbad festsetzen können und den Durchgang behindern oder die Entwicklungsflüssigkeit selbst verunreinigen.tact with the layer transfer sheet is maintained. In addition, it is avoided that soft, uncured Gelatin parts can stick to the guides of the film in the treatment bath over time and obstruct the passage or contaminate the developing liquid itself.
Außerdem ist es möglich, mit höheren Temperatüren und hiermit auch mit erhöhter Entwicklungsgeschwindigkeit im Behandlungsgerät zu arbeiten, was das Verfahren nicht nur rationeller, sondern auch insofern sicherer macht, als die weiche Gelatine von höherer Temperatur eine bessere Klebkraftneigung zu dem später aufgeführten Schichtübertragungsblatt hat. Das Verfahren wird hierdurch auch brauchbarer gemacht für Tropenzonen mit Raumtemperaturen bis zu 35° C, während nach den früheren Verfahren nur mit Raumtemperaturen unter 29° C gearbeitet werden konnte.In addition, it is possible to work with higher temperatures and thus also with increased development speed in the treatment device, which makes the process not only more efficient but also safer than the soft gelatine the higher the temperature, the better the tendency to adhere to the later-mentioned layer transfer sheet Has. This also makes the method more useful for tropical zones with room temperatures up to 35 ° C, while according to the earlier method only with room temperatures below 29 ° C could be worked.
Zur näheren Erläuterung des Verfahrens wird folgendes Beispiel angeführt:The following example is given to explain the process in more detail:

Nach einer Trockenzeit von gekennzeichnet, daß auf einem Blatt Papier, etwa 10 Minuten werden beide Blätter getrennt, 35 Kunststoff od. dgl. eine Schicht aus gerbenden hierbei wird die Farbe von dem Farbblatt an den Entwicklersubstanzen oder einer alkalisch reagie-Bildstellen abgehoben und haftet fest auf der Folie. renden Substanz und einer Gelatine weich-Diese so entstandene Spiegelbildmatrize kann auf machenden Substanz in stabilisierter Form als jedem hektographischen Umdrucker abgezogen Schicht aufgebracht, mit diesen Stoffen getränkt werden. 40 oder diese Stoffe eingearbeitet sind.When the two sheets are separated, the equivalent substances, in addition to the tanned, tanned gelatin, are transferred to the lift-off sheet, while the unhardened gelatin is used on the image areas of the substances, while developing substances or those with an alkaline reaction are used,
cleared film remains. A hectographic drive according to claims 1 and 2 is pressed against the film with the third lifting sheet for the execution of the softening gelatin relief. After a drying time of marked that on a sheet of paper, about 10 minutes, both sheets are separated, 35 plastic or the like. A layer of tanning here the color is lifted from the color sheet at the developer substances or an alkaline reactive image areas and adheres firmly on the slide. The resulting mirror image matrix can be applied to the making substance in a stabilized form as a layer peeled off from every hectographic transfer printer, and soaked with these substances. 40 or these substances are incorporated.
