Description
Verfahren zum Färben des Schichtträgers bei Bildtonfilmen in der Breite der Bildfläche Versucht man den Schichtträger, also das Celluloid, eines Bildtonfilmes nur an den Stellen einzufärben, die ,der Bildfläche entsprechen, so kann sich wegen der ungleichmäßigen Benetzung durch die färbende Lösung nach dem Trocknen der Film mehr oder weniger verändern, etwa verziehen oder schrumpfen. Die Ursache dieses Übelstandes ist in dem Verdampfen des Weichmachungsmittels zu suchen, die durch das Lösungsmittel gelockert werden und daher mit ihm teilweise verdampfen.Process for coloring the support in the case of image-tone films in width of the image area If you try the layer support, i.e. the celluloid, of an image tone film to be colored only in the places that correspond to the picture surface, it can be because of the uneven wetting by the coloring solution after the film has dried change more or less, such as warping or shrinking. The cause of this The problem lies in the evaporation of the plasticizer, which occurs through the solvent are loosened and therefore partially evaporate with it.
Diesen Verlust an Weichhaltungsmitteln vermeidet man erfindungsgemäß dadurch, daß man in den Schichtträger vor der Färbung so viele Weichhaltungsmittel mittels Ouellung einbringt, daß die Abnahme durch Verdampfung wieder ausgeglichen wird. Der Film behält also stets den gleichen Prozentsatz an Weichhaltungsmitteln und schrumpft daher nicht.According to the invention, this loss of softeners is avoided by adding as many softeners to the substrate before dyeing brings in by means of Ouellung that the decrease is compensated again by evaporation will. The film always retains the same percentage of softeners and therefore does not shrink.
Als Beispiel sei folgendes Verfahren angegeben: Man wendet zuerst eine Lösung von ,Io °/o Kampfer oder entsprechend Kampferersatzmitteln, gelöst in einer Mischung aus Äther, Alkohol und Aceton, an und trägt diese Lösung auf die volle Breite des Filmes, also von Rand zu Rand auf, was bekanntlich bei den jetzt üblichen Normalfilmen 35 mm ausmacht. Auf den so vorbereiteten und gequollenen Film trägt man nunmehr die Farbstofflösung in der Breite eines Bildes auf, die beispielsweise eine in Alkohol gelöste Farbe sein kann. Nach dem Trocknen ist der Film vollkommen schrumpfungsfrei und in seinen Abmessungen unverändert verwendungsfähig.The following procedure is given as an example: You turn first a solution of, Io ° / o camphor or equivalent camphor substitutes, dissolved in a mixture of ether, alcohol and acetone, and applies this solution to the full width of the film, so from edge to edge on what is known with the now common normal films is 35 mm. The film so prepared and swollen you now apply the dye solution in the width of an image, for example can be a paint dissolved in alcohol. After drying, the film is perfect shrinkage-free and usable in its dimensions unchanged.
Die erforderlichen Einrichtungen können auch so getroffen werden, daß das Quellen bzw. Imprägnieren und darauffolgen.de Einfärben in einem Arbeitsgange geschehen.The necessary facilities can also be made in such a way that that the swelling or impregnation and subsequent.de coloring in one operation happen.
Bei Sicherheitsfilmen aus Acetatcellulose verwendet man eine Lösung aus: Phthalsäurediäthylester, Glykolacetat, Essigäther und Spiritus, deren genauere Zusammensetzung je nach dem vorliegenden Material wechselt.A solution is used with acetate cellulose security films from: Phthalic acid diethyl ester, glycol acetate, vinegar ether and spirit, their more precise Composition changes depending on the material present.
Von einem bekannten Verfahren zum Anfärben des Schichtträgers an den dem Bilde entsprechenden Teilen unterscheidet sich das vorliegende Verfahren durch .die Anwendung der Weichmachungsmittel in den zum Färben dienenden Lösungen. Erst hierdurch wird ein solcher gefärbter Film erzielt, der sich bei dem Trocknen und der späteren Verwendung nicht verzieht, sondern etwa bei dem Schrumpfen oder Dehnen ganz gleichförmig ändert.Of a known method for coloring the support to the The present method differs in parts corresponding to the picture the use of plasticizers in the solutions used for dyeing. First in this way, such a colored film is achieved, which during drying and not warped during later use, but rather during shrinking or stretching changes quite uniformly.
