Description
Die Erfindung betrifft ein Verfahren und Farbblatt zur Herstellung von hektographischen Abzügen, bei dem auf einem lichtempfindlichen Material, dessen Silberhalogenidemulsion einen durchleuchtungsfähigen, klebfähig zu machenden Stoff, z. B. die Leukobase eines Triphenylmethanfarbstoffes, enthält, eine photographische Reproduktion erzeugt wird. Hierbei wird von diesem Material auf photographischem Wege in gehärteter Gelatine als Druckform ein positives Reliefspiegelbild des Originals unter Anwendung des Herschel-Effektes gebildet.The invention relates to a method and ink sheet for producing hectographic prints on a light-sensitive material, the silver halide emulsion of which has a translucent, fabric to be made adhesive, e.g. B. the leuco base of a triphenylmethane dye, contains a photographic reproduction is produced. This material is used for photographic purposes Ways using hardened gelatin as a printing form using a positive relief mirror image of the original of the Herschel effect.
Nach dem in dem Hauptpatent beschriebenen Verfahren wurde eine unter Anwendung des Herschel-Effektes im Reflexwege oder Durchleuchtungswege belichtete Papierdruckform mit einer Gelatineschicht an den Bildstellen gerbend entwickelt und durch eine wäßrige Lösung einer Verbindung die Silberhalogenidemulsion der Druckform an den Bildstellen klebfähig gemacht.According to the method described in the main patent, one using the Herschel effect Paper printing form exposed in the reflex path or fluoroscopic path with a gelatin layer Developed tanning at the image areas and the silver halide emulsion developed by an aqueous solution of a compound the printing form made adhesive at the image areas.
Die Erfindung hat den weiteren Ausbau und die Verbesserung der Erfindung nach Patent 1124 977 zum Gegenstand.The invention has the further development and improvement of the invention of patent 1,124,977 to the subject.
Erfindungsgemäß wird die Druckform unter Anwendung von Druck mit der Schichtseite eines hektographischen Farbblattes in Kontakt gebracht, welches über der Farbschicht eine latente Klebstoffschicht besitzt. Die latente Klebstoffschicht wird entweder durch die Behandlungsflüssigkeit der Druckform allein oder zusätzlich vermittels einer in die Gelatineschicht eingearbeiteten, vorzugsweise latenten Klebstoffkomponente zu den gehärteten Gelatinebildstellen der Druckform klebfähig gemacht. Bei Trennung der Druckform von dem hektographischen Farbblatt geht die latente Klebstoffschicht mit der Farbstoffschicht des hektographischen Farbblattes an den Bildstellen auf die Druckform über. Dies kann allein durch die Wirkung von der Behandlungsflüssigkeit der Druckform mit der Klebstoffschicht des Farbblattes erfolgen oder eben auch dadurch, daß die in der Druckform eingearbeitete latente Klebstoffkomponente mit der Kleb-Stoffschicht des Farbblattes zusammen unter Einwirkung der Behandlungsflüssigkeit der Druckform eine festbindende Klebung ergibt.According to the invention, the printing form is made using pressure with the layer side of a hectographic Brought into contact with the ink sheet, which has a latent adhesive layer over the ink layer. The latent adhesive layer is either alone or by the treatment liquid of the printing form additionally by means of a preferably latent adhesive component incorporated into the gelatin layer made adhesive to the hardened gelatin image areas of the printing form. When separating the printing form from the hectographic ink sheet the latent adhesive layer goes with the dye layer of the hectographic ink sheet at the image points on the printing form. This can be done by the effect alone from the treatment liquid of the printing form with the adhesive layer of the ink sheet or also because the latent adhesive component incorporated in the printing form is connected to the adhesive layer of the ink sheet together under the action of the treatment liquid of the printing form tight bonding results.
Die Gelatineschicht an den bildfreien Stellen kann hierbei vorzugsweise vorher durch Reinigung, z. B.
Abwaschen mittels mechanischer Reibung, entfernt worden sein, so daß an den bildfreien Stellen keine
Klebstoffwirkung zum Farbblatt entsteht. Es ist jedoch aber auch möglich, die Gelatineschicht an den bildfreien
Stellen durch Aufdrücken eines Abdrückblattes zu entfernen. Im letzteren Fall empfiehlt es sich,
die nichtgehärtete Gelatine durch geeignete Mittel Verfahren und Farbblatt zur Herstellung
von hektographischen AbzügenThe gelatin layer at the non-image areas can preferably be cleaned beforehand, e.g. B. washing by means of mechanical friction, have been removed so that there is no adhesive effect to the ink sheet in the non-image areas. However, it is also possible to remove the gelatin layer from the non-image areas by pressing on a release sheet. In the latter case, it is recommended that the non-hardened gelatin is prepared by suitable means and method and color sheet
of hectographic prints

ζω einer zusammenhängenden Schichtmasse zu koagulieren. ζω to coagulate a coherent layer mass.
Es kann auch so gearbeitet werden, daß an Stelle des Abdrückblattes sofort das hektographische Farbblatt mit der latenten Klebstoffschicht aufgedrückt wird. Es geht dann bei Trennung an den Bildstellen die Farbschicht auf die Druckform und an den bildfreien Stellen die nichtgehärtete, vorzugsweise koagulierte Gelatine auf das Farbblatt über.It is also possible to work in such a way that the hectographic ink sheet immediately replaces the impression sheet is pressed on with the latent adhesive layer. It then goes with separation at the image areas the ink layer on the printing form and in the non-image areas the non-hardened, preferably coagulated Gelatin onto the colored sheet.
Die verwendeten Farbblätter können über einer vervielfältigungsfähigen Farbschicht, bestehend aus einem vervielfältigungsfähigen Farbstoff verbunden mit Wachsen und Fetten, eine latente Klebstoffschicht besitzen, welche durch eine Flüssigkeit oder in Verbindung mit einer anderen Klebstoffkomponente klebfähig gemacht werden kann.The color sheets used can be over a reproducible color layer consisting of a duplicable dye combined with waxes and fats, a latent adhesive layer have which are adhesive due to a liquid or in connection with another adhesive component can be made.
Die Erfindung kann beispielsweise wie folgt ausgeführt werden:The invention can for example be carried out as follows:
Auf die hektographischen Farbblätter mit den bekannten Farbstoffschichten wird eine Kolloidschicht, z. B. aus Dextrin, Gummiarabikum, Gelatine, Polyvinylalkohol, Alginate, Stärke, Cellulosederivate wie Karboxymethylcellulose oder Methylcellulose, aufgebracht. A colloid layer is placed on the hectographic color sheets with the known dye layers z. B. from dextrin, gum arabic, gelatin, polyvinyl alcohol, alginates, starch, cellulose derivatives such as Carboxymethyl cellulose or methyl cellulose.
Zum Befeuchten der Druckform werden wäßrige Lösungen von Verbindungen gewählt. Diese wäßrigen Lösungen können Zusätze von Alaun, Tannin, Borsäure, Bichromate od. dgl. enthalten. In die Gelatineschicht der Druckform können als latente Klebstoff-Aqueous solutions of compounds are chosen to moisten the printing form. This aqueous Solutions can contain additions of alum, tannin, boric acid, bichromates or the like. In the gelatin layer the printing form can be used as latent adhesive

Um die in der Druckform enthaltenen latenten Klebstoffe wirksam zu machen, sind in diesem Fall in die latente Klebstoffschicht des Farbblattes saure Verbindungen, z. B. anorganische saure Salze oder organische oder anorganische feste Säuren, eingearbeitet.About the latent adhesives contained in the printing form In this case, acidic compounds are to be made effective in the latent adhesive layer of the ink sheet, z. B. inorganic acid salts or organic or inorganic solid acids incorporated.
