Description

Verfahren zur Herstellung von gegen mechanische Fälschung gesicherten Schriftstücken, Wertpapieren o. dgl. Die allgemein üblichen Schreib- und Druckpapiere machen @es sehr leicht, die Beschriftung mit mechanischen Mitteln zu entfernen. Zum Schutz hiergegen hat man das Papier ganz oder teilweise mit einer Schraffwr oder einem sonstigen Untergrunde versehen. Diese Maßnahme verfehlt indes in vielen Fällen ihren Zweck, weil der gedruckte Untergrund auf normalem Papier meist so widerstandsfähig ist, daß die Beschriftung ganz oder teilweise entfernt werden kann, ohne daß eine sofort ins Auge fallende Beschädigung des Untergrundes ,dieses anzeigt. Dies gilt insbesondere dann, wenn -die Eintragung in dem heute sehr verbreiteten Durchschreibeverfahren bewirkt ist.Process for the production of secured against mechanical forgery Documents, securities or the like. The commonly used writing and printing papers make @it very easy to remove the lettering by mechanical means. To protect against this, all or part of the paper has been hatched or any other surface. However, this measure fails in many They serve their purpose because the printed background on normal paper is usually so resistant is that the lettering can be completely or partially removed without a immediately noticeable damage to the subsurface, indicating this. this applies especially if the entry is made in the carbonless copying process that is very common today is effected.

Demgegenüber bietet die den Gegenstand der Erfindung bildende Verwendung von langfaserigem, schwach geleimtem Papier den Vorteil, daß jeder Verstuch, eine Eintragung durch mechanische Mittel ganz oder teilweise zu entfernen, durch sofort deutlich sichtbare Beschädigung der Papieroberfläche erkennbar gemacht wird.In contrast, offers the use forming the subject of the invention long-fiber, weakly sized paper has the advantage that every attempt, one Entries by mechanical means can be completely or partially removed by immediately clearly visible damage to the paper surface is made recognizable.

Die Verwendung langer Fasern für die Herstellung von Sicherheitspapieren ist an sich nicht neu. Zweck dieser Art von Verwendung langer Fasern ist es, ein leicht erkennbares und dabei schwer nachzuahmendes Merkmal für die Echtheit des Papiers als solchen zu schaffen. Man fügt dem Papierbrei in verhältnismäßig geringen Mengen Fasern bei, die sich durch ihre Farbe von der übrigen Papiermasse unterscheiden und so im fertigen Papier ein Kennzeichen für die Echtheit desselben bilden.The use of long fibers for the production of security papers is not new in itself. The purpose of using this type of long fiber is to provide a easily recognizable and difficult to imitate feature for the authenticity of the To create paper as such. Relatively small amounts are added to the pulp Amount of fibers that differ from the rest of the paper pulp by their color and thus form a mark of authenticity in the finished paper.

Die Neuheit der den Gegenstand des vorliegenden Patentanspruches bildenden Erfindung beruht darauf, :daß. die außerordentlich große Oberflächenempfindlichkeit von Papieren mit einem hohen Prozentsatz langer Fasern und genügend schwach gewählter Leimeng dazu benutzt wird, mechanische Radierversuche durch auffällige Beschädigung der Papieroberfläche ersichtlich zu, manchen.The novelty of the subject of the present claim Invention is based on: that. the extraordinarily high surface sensitivity of papers with a high percentage of long fibers and sufficiently weak ones Leimeng is used to attempt mechanical erasure due to conspicuous damage the surface of the paper is evident to some.

Das langfaserige, schwach geleimte Papier kann in bekannter Weise mit einem Untergrunddruck versehen werden. Zum Schutz gegen chemische Ab:änderungsversuche kann das Papier, wie gleichfalls bekannt, geeignete Chemikalienzusätze erhalten.The long-fiber, weakly sized paper can in a known manner be provided with a background print. To protect against chemical modification attempts the paper can, as is also known, contain suitable chemical additives.
