Description

Verfahren zur Herstellung von Kohlenpapier Die Erfindung betrifft eine weitere Ausbildung des in der Patentschrift 518273 beschriebenen Verfahrens zur Herstellung von Kohlenpapier.Process for the production of carbon paper The invention relates to a further embodiment of the process for the production of carbon paper described in patent specification 518273.

Es hat sich gezeigt, daß die in der Patentschrift 518273 beschriebenen Vorteile, insbesondere die hohe Ergiebigkeit des Kohlenpapiers, auch dadurch erreicht werden können, daß die zwischen dem Papier und der farbabgebenden Schicht liegende Zwischenschicht aus natürlichen oder künstlichen Harzen, Estern hergestellt wird, gegebenenfalls unter Zusatz von Weichmachungsmitteln, Vulkanisationsmitteln und Vulkanisationsbeschleunigern.It has been shown that those described in patent 518273 Advantages, in particular the high yield of the carbon paper, also achieved thereby can be that the lying between the paper and the ink-releasing layer Intermediate layer is made from natural or synthetic resins, esters, optionally with the addition of plasticizers, vulcanizing agents and Vulcanization accelerators.

Aus den gleichen Stoffen kann auch die Deckschicht bestehen, welche gegebenenfalls noch auf die farbabgebende Schicht aufgebracht werden kann.The top layer can also consist of the same materials, which optionally can also be applied to the color-releasing layer.

Auch die nach dem vorliegenden Verfahren hergestellten Kohlenpapiere weisen den bereits in Patent 518 273 hervorgehobenen Vorteil auf, daß man auf die Zwischenschicht eine merklich dickere, farbabgebende Schicht auftragen kann als bei den bekannten Kohlenpapieren, ohne ein Brechen oder Abblättern der farbabgebenden Schicht befürchten zu müssen. Durch diese dickere, farbabgebende Schicht wird die Gebrauchsdauer des Kohlenpapiers verlängert.Also the carbon papers produced by the present process have the advantage already highlighted in patent 518 273 that one can access the Interlayer can apply a noticeably thicker, color-releasing layer than with the known carbon papers, without breaking or peeling of the color-releasing paper To have to fear shift. This thicker, color-releasing layer makes the The service life of the carbon paper is extended.
