  Verfahren zur Herstellung von Farbstoff abgebenden Blättern. 



   Die Herstellung von Kopien mittels des Durchschreibeverfahrens hat sich wegen der   grossen   Vorteile, die es bietet, in   der Geschäftswelt immer mehr   und mehr   eingebürgert.   Zur Erzeugung dieser Kopien verfuhr man bisher in der Weise, dass man sogenannte Kohlepapiere verschiedener Färbung zwischen die einzelnen zu beschreibenden Blätter legte. Diese Kohlepapiere wurden bisher nach dem bekannten Streichverfahren hergestellt. 



   Es ist ferner bekannt, die Anwendung besonderer Kohlepapiere dadurch zu   vermeiden,     dass die Rückseite des zu beschreibenden Blattes direkt mit Farbstoff versehen wird. Aber auch   in diesem Falle wird der Farbstoff in der gleichen Weise aufgebracht, wie bei der Herstellung besonderer   Kohlepapiere.   Bei dem bekannten Streichverfahren ist es nun nicht möglich, auf den zu präparierenden Flächen Aussparungen anzubringen, verschiedene Farben anzuwenden oder Raster oder dessinartig bedruckte Flächen herzustellen. Nun bestellt aber aus bestimmten Gründen ein Bedürfnis, auch solche Farbe abgebende   Schichten erzeugen zu können, bei denen   nicht die   ganze Fläche mit   dem Farbstoff versehen ist. 



   Dieser Zweck wird durch vorliegende Erfindung dadurch erreicht, dass man sich zum Aufbringen oder kopierenden Farbschicht hiezu eines beliebigen Druckverfahrens bedient. Das Bedrucken der in Frage kommenden Flächen mit entsprechender Farbe kann z. B. durch Steindruck oder Buchdruck geschehen. Die zur   Verwendung kommenden Druckstöckf, Walzen.

 bedruckt werden, die   zur Hervorbringung   des sonst   üblichen, nötigen und gewünschten   Textoder Formulardruckes auf der   Vorderseite der Papiere dienen. Während nach de@ bekannten  
Verfahren das   betreffende Formular erst gedruckt werden muss,   und dann die die Farbe abgebende 
 EMI1.2 
 
Fläche mit verschiedenen Farben versehen werden.

   Die Aufbringung dieser verschiedenen Farben   5 erfolgt dann wie beim Mehrfarbendruck. Aus den nach dem obigen Verfahren hergestellten Blättern können Bücher der verschiedensten Art erzeugt werden.

  Process for making dye releasing sheets.



   The production of copies by means of the carbon copy process has become more and more common in the business world because of the great advantages it offers. To produce these copies, the previous approach was to place so-called carbon papers of various colors between the individual sheets to be written on. These carbon papers were previously produced using the known coating process.



   It is also known to avoid the use of special carbon papers by directly providing the back of the sheet to be written with dye. But also in this case the dye is applied in the same way as in the production of special carbon papers. With the known painting process, it is not possible to make cutouts on the surfaces to be prepared, to use different colors or to produce raster or design-like printed surfaces. For certain reasons, however, there is a need to be able to produce color-releasing layers in which the entire surface is not provided with the dye.



   This purpose is achieved by the present invention in that any printing method is used for applying or copying the color layer. The printing of the areas in question with the appropriate color can, for. B. done by lithography or letterpress. The printing blocks and rollers to be used.

 are printed, which serve to produce the otherwise usual, necessary and desired text or form printing on the front of the papers. While after de @ known
Procedure, the form in question must first be printed, and then the one that emits the color
 EMI1.2
 
Surface can be provided with different colors.

   These different colors 5 are then applied as in multi-color printing. Various types of books can be produced from the sheets produced by the above process.
