Description

Verfahren zur gleichmäßigen Verbindung der Emulsion mit dem Metallfilm. Überzieht man einen Aluminium- oder anderen Metallfilm mit der lichtempfindlichen Emulsion, so haftet dieselbe zwar zunächst, blättert und bröckelt aber leicht. ab, wenn der Bildträger bei trockener Schicht gebogen wird, oder wenn letztere eine leichte mechanische Verletzung erfährt. Es scheint auch das verschiedene Wärmeleitungsvermögen zwischen Auflage und Träger eine ungünstige Rolle zu spielen. Behoben werden diese Übelstände durch Verwendung einer teils ausgleichenden, teils isolierenden Schicht zwischen Film und Emulsion. Je neutraler difse Schicht ist, um so vorteilhafter wirkt sie.Method of uniformly bonding the emulsion to the metal film. One covers an aluminum or other metal film with the photosensitive one Emulsion, then it adheres at first, but flakes and crumbles easily. away, when the image carrier is bent when the layer is dry, or when the latter is a experiences slight mechanical injury. It also seems the different thermal conductivity to play an unfavorable role between support and carrier. These are fixed Deficiencies through the use of a partly compensating, partly insulating layer between film and emulsion. The more neutral the different layer, the more advantageous it works.

Dieselbe besteht aus Gelatine, der man in Lösung vor dem Auftragen auf den Film wassergelöste (dialysierte) Kieselsäure zugesetzt hat. Die Menge dieses Zusatzes richtet sich nach der beabsichtigten Stärke der Gelatinezwischenschicht. Man kann diese Mischung bei Verwendung von Aluminiumfilmen schwach alkalisieren, um durch den hauchartigen Oberflächenangriff eine ncch festere Verbindung dieser Schicht mit der Unterlage herbeizuführen. Auf die Zwischenschicht wird die Emulsion in sonst üblicher Weise aufgebracht.It consists of gelatin, which is put in solution before application added water-dissolved (dialyzed) silica to the film. The amount of this The addition depends on the intended thickness of the gelatin intermediate layer. You can make this mixture slightly alkaline when using aluminum films, in order to create an even more solid connection between them due to the puff-like surface attack Bring about a layer with the underlay. The emulsion is applied to the intermediate layer applied in the usual way.

Eine derart aufgebrachte Emulsion haftet elastisch und blättert nicht, auch nicht bei Krümmungen und Biegungen des Films.An emulsion applied in this way adheres elastically and does not peel, not even with curvatures and bends in the film.
