Description
Verfahren zur Fixierung der Farbschicht auf carbonisierten Geschäftsformularen. Das Verfahren bezieht sich auf das Fixieren von abfärbenden, carbonisierten Formularen. Das Verfahren besteht darin, daß die Farbschicht auf carbonisierten Formularen mit einer Lösung von etwa 2o Gewichtsprozenten Kolophonium in Ligroin vom Siedepunkt 65 bis 8o' behandelt wird, wodurch die Farbschicht fixiert wird. Es wird dies dadurch erreicht, daß die Formulare durch zwei übereinander angeordnete, gegeneinander sich drehende Glaswalzen hindurchgedreht werden. Die untere Glaswalze liegt in einer Wanne, in welcher die Ligroin-Kolophonium-Lösung durch eine einfache Vorrichtung auf konstantem Niveau erhalten wird. Die durchgedrehten Papiere trocknen infolge des niedrigen Siedepunktes des Ligroins sofort an der Luft, wobei die Farbschicht durch die Klebkraft des Kolophoniums gebunden wird und nicht mehr abfärbt. Die Lesbarkeit der Schriftzeichen auf der Vorderseite der Formulare wird nicht beeinträchtigt.Method of fixing the color layer on carbonized business forms. The process relates to the fixing of staining, carbonized forms. The process consists in applying the color layer on carbonized forms using a solution of about 20 percent by weight rosin in ligroin at the boiling point 65 to 8o 'is treated, whereby the color layer is fixed. It becomes this through it achieved that the forms by two superimposed, against each other rotating glass rollers are turned through. The lower glass roller lies in one Tub in which the ligroin-rosin solution is stored in a simple device is maintained at a constant level. The twisted papers dry as a result the low boiling point of ligroin immediately in the air, whereby the color layer is bound by the adhesive strength of the rosin and no longer rubs off. The readability the characters on the front of the forms are not affected.
Das Verfahren kann in allen Bank- und Handelsbetrieben angewandt werden, in denen carbonisierte Formulare angewandt werden. Es beseitigt den bisher bestehenden großen Nachteil des unerwünschten Abfärbens dieser Formulare nach erfolgter Durchschrift.The procedure can be used in all banking and trading operations, in which carbonized forms are used. It eliminates the previous one major disadvantage of the undesired coloration of these forms after copying.
Der wesentliche Fortschritt liegt darin, daß bei Anwendung dieses Verfahrens carbonisierte Formulare auch in allen den Fällen benutzt werden, können, in denen dieses wegen des dauernden Abfärbens bisher nicht möglich war.The main progress is that when using this Process carbonized forms can also be used in all cases in which this was previously not possible because of the permanent coloration.
Es ist an sich bekannt, daß man zur Fixierung von Zeichnungen, Pastellen u. dgl. Verfahren anwendet, die dem in der Patentschrift beschriebenen ähnlich sind.It is known per se that one can fix drawings, pastels and the like employ methods similar to that described in the patent.
Die Erfindung liegt jedoch in der Anwendung des beschriebenen Fixativs bei carbonisierten Geschäftsformularen.However, the invention resides in the use of the fixative described with carbonized business forms.
