Description

Verfahren zur Herstellung von zwei Lichtpausen in einem Arbeitsgange. Der Gegenstand vorliegender Erfindung bezieht sich auf die Herstellung von zwei Lichtpausen in einem Arbeitsgange, die eine auf sehr ,dünnem Papier (Gewicht unter 4o bis 45 g pro Quadratmeter), die zweite auf stärkerem Papier.Process for the production of two blueprints in one operation. The subject matter of the present invention relates to the manufacture of two Blueprints in a work process, one on very thin paper (weight under 40 to 45 g per square meter), the second on thicker paper.

Zur Herstellung der beiden Lichtpausen in einem Arbeitsgange wird Duplexpapier verwendet. Letzteres ist an sich bekannt; es besteht aus zwei Papierschichten, die eine aus dünnem Seidenpapier und die andere aufs stärkerem Papier. 'Beide Papierschichten werden auf der Papiermaschine aufeinandergequetscht. Nach dem Trocknen .der ;so erhaltenen Doppelschicht kann die .dünne von der dicken Papierschicht albgezogen wenden.To produce the two blueprints in one operation Duplex paper used. The latter is known per se; it consists of two layers of paper, one made of thin tissue paper and the other on thicker paper. 'Both layers of paper are squeezed together on the paper machine. After drying .the; so The double layer obtained can be pulled from the thick paper layer turn around.

Es sind nun bisher schon Duplexpapiere für photographische Zwecke verwendet, und zwar für den Negativ- als auch für den Positivpro-zeß. Hierbei wird die dünne Papierschicht in bekannter Weise mit Emulsion behandelt, -und das auf der dünnenPapierschicht erzeugte Negativ oder Positiv kann nach dem Trocknen von der dicken Papierschicht abgezogen werden.There are now already duplex papers for photographic purposes used, both for the negative and for the positive process. Here is the thin paper layer treated in a known manner with emulsion, -and that on The negative or positive produced by the thin paper layer can after drying of peeled off the thick paper layer.

Bei der vorliegenden Erfindung handelt es sich um Duplexpapier zur Herstellung von dünnen leichten Lichtpausen und :gleichzeitig zur Herstellung von zwei Lichtpausen in einem Arbeit>s.gange. Zu diesem Zwecke wird das Duplexpapier auf ,der Seite, welche die dünne Papierschicht trägt, mit der Flüssigkeit bestrichen, jedoch derart, daß letztere durch die dünne Schicht hindurchdringt .und, auch die @darunterliegende idiiekere Papierschicht benetzt. Das so erhaltene Duplexlichtpauspapier wind in der üblichen Weise behandelt, d. ih. belichtet, gewässert und getrocknet. Nachdem Trocknen wind die .dünne Papierschicht abgezogen, und man erhält so zwei gleiche Lichtpausen, die eine auf dünnem und! die zweite auf dickerem Papier. , Ausführungsbeispiel für die lichtempfindlich machende Lösung.The present invention is duplex paper for Production of thin light blueprints and: at the same time for the production of two blueprints in one work> s.gange. For this purpose, the duplex paper is used smeared with the liquid on the side that bears the thin paper layer, but in such a way that the latter penetrates through the thin layer .and, also the @bellying idiiekere paper layer wetted. The duplex tracing paper thus obtained wind treated in the usual way, d. ih. exposed, watered and dried. After drying, the thin layer of paper is peeled off and you get two same blueprints, the one on thin and! the second on thicker paper. , Embodiment for the photosensitive solution.

r. In 5 1 heißem Wasser wenden 40009 Grüneisen, 9oog Zitronensäure gelöst und so viel Wasser hinzugefügt, bis. das Ganze ro 1 Flüssigkeit ergibt.r. Turn 40009 Grüneisen, 9oog citric acid in 5 liters of hot water dissolved and added as much water until. the whole thing results in ro 1 liquid.

2. In 5 1 heißem Wasser werden z ooo g rotes Blutlaugensalz, 5o g Kaliumbichromat gelöst und so viel Wasser hinzugefügt, Ibis auch dieses, ro l Flüssigkeit gibt.2. In 5 liters of hot water, z ooo g of red blood liquor salt, 50 g Dissolved potassium dichromate and added as much water, ibis this too, ro l liquid gives.

Diese beiden so erhaltenen Zusammensetzungen bilden Vorratslösungen.These two compositions thus obtained form stock solutions.

Um hieraus. !die streichfertige lichtempfindliche Lösung herzustellen, werden genommen 500 ccm Vorratslösung Nr. r, 200 - - - 2, 300 - kaltes reines Wasser, was r ooo ccm streichfertige Lösung ergibt. To get out of here. ! to prepare the ready-to-apply photosensitive solution are taken 500 cc stock solution No. r, 200 - - - 2, 300 - cold pure water what r ooo ccm of ready-to-use solution.
