Description

Verfahren zur Herstellung von Registrierpapier Unter Registrierpapier versteht man bekanntlich ein Papier, welches mit einer weichen, durch einen- Schreibstift einritzbaren Deckschicht versehen ist. Gewöhnlich wird der Papiergrund gefärbt und die Deckschicht weiß gehalten, so daß beim Einritzen der Deckschicht der gefärbte Grund hervortritt und dadurch die geritzte Kurve deutlich sichtbar wird.Process for the production of recording paper Under recording paper is known to understand a paper, which with a soft, through a pen scratchable cover layer is provided. Usually the paper ground is colored and the top layer kept white, so that when the top layer is scratched the colored The bottom protrudes and the scratched curve is clearly visible.

Es ist bekannt, der Deckschichtlösung bei derartigen Registrierpapieren Kollodiu.m-Lösungen zuzusetzen, um die Schicht elastisch zu machen. Wenn man Köllodiumlösung zur Deckschicht hinzugibt, ist jedoch ein Lösungsvermittler notwendig. Bekanntlich wird- die Masse, aus welcher die Deckschicht besteht, beispielsweise Stearin oder Paraffin, dem gegebenenfalls noch Härtungsstoffe zugesetzt sein können, in Benzin oder Benzol bzw. einem Gemisch der beiden Flüssigkeiten gelöst. Kollodium löst sich aber in Benzin oder Benzol schlecht auf. Man verwendet bekanntlich Azur Herstellung der Kollodiumlösung Alkohol oder Äther. Setzt man diese Kollodiumlösung der Deckschichtmasse zu, so fällt das Kollodium aus, und man ist gezwungen, noch etwas Alkohol hinzuzufügen. Der Alkohol beeinflußt aber wieder die Eigenschaften der Deckschichtlösung in ungünstigem Sinn, weil er ein schlechtes Lösungsmittel für die darin enthaltenen Stoffe darstellt.It is known that the top layer solution in such recording papers Add Kollodiu.m solutions to make the layer elastic. If you have colodium solution added to the top layer, however, a solubilizer is necessary. As is well known - the mass from which the top layer consists, for example stearin or Paraffin, to which hardening agents can optionally also be added, in gasoline or benzene or a mixture of the two liquids. Collodion dissolves but performed badly in gasoline or benzene. It is well known that azure production is used the collodion solution alcohol or ether. If you put this collodion solution of the top layer mass too, the collodion precipitates and one is forced to add a little more alcohol. However, the alcohol again has an unfavorable effect on the properties of the top layer solution Sense, because it is a bad solvent for the substances it contains.

Es ist nun gefunden worden, daß diese Schwierigkeit vollkommen beseitigt werden kann, wenn man an Stelle von Kollodium zu der Decks.chichtmasse Chlorkautschuk hinzusetzt. Chlorkautschuk ist in Benzin und Benzol sowie in dem Gemisch der beiden Flüssigkeiten sehr gut löslich. Es ist daher nicht erforderlich, Lösungsmittel hinzuzufügen, welche die Löslichkeit der zur Herstellung der Deckschicht verwendeten Stoffe im Benzin-Benzol-Gemisch herabsetzen. Andererseits erteilt der Chlorkautschuk der Deckschicht eine besonders große Elastizität.It has now been found that this difficulty is completely eliminated can be achieved if, instead of collodion, chlorinated rubber is used for the deck layering compound added. Chlorinated rubber is found in gasoline and benzene as well as in the mixture of the two Liquids very soluble. It is therefore not necessary to add solvents, which the solubility of the substances used to produce the top layer in Reduce the gasoline-benzene mixture. on the other hand issued by chlorinated rubber the top layer has a particularly high elasticity.

Die Lösungen von Chlorkautschuk, welche man als Zusatz zur Deckschichtlösung benutzt, sind kolloid. Sie eignen sich daher ganz besonders gut zur Verwendung in Deckschichten, die aus kolloiden Lösungen aufgetragen werden. Derartige Lösungen sind bei-; spielsweise in Aufschlämmungen, welche zu-;-Stande kommen, wenn man Metallstearate iriit. ` Lösungsmitteln behandelt, die nur wenig da!',', von aufzulösen vermögen, und die Verhältnisse so einrichtet, daß sich in der vorhandenen Flüssigkeitsmenge nur ein Teil der Stoffe aufzulösen vermag.The solutions of chlorinated rubber, which are used as an additive to the top coat solution, are colloidal. They are therefore particularly suitable for use in top layers that are applied from colloidal solutions. Such solutions are both; for example in slurries, which arise when one iriit metal stearates. Treats solvents that are only able to dissolve a little ! '
