Description

Verfahren zum Vorbereiten von Chromatgelätinereliefs für das galvanische Abformen Es ist bereits bekannt, auf nicht leitende Gegenstände, z. B. aus Gelatine, vor dem elektrolytischen Überziehen mit Metallen wasserunlösliche und quellunfähge überzüge aufzubringen und diese darauf stromleitend zu machen.Process for preparing chromate gelatin reliefs for electroplating Molding It is already known that non-conductive objects, e.g. B. from gelatine, water-insoluble and non-swellable prior to electrolytic coating with metals to apply coatings and to make them conductive.

- Um die Oberflächen von belichteten Gelatineschiichten vor dem Angriff des elektrolytischen Bades zu schützen, werden diese vor dem Leitendmachen und Abformen mit Lösungen von Filmbildnern überzogen.- To the surfaces of exposed gelatin layers before attack To protect the electrolytic bath, these are made conductive and molded covered with solutions from film formers.

Demgegenüber bezieht sich die vorliegende Erfindung auf ein Verfahren zum Vorbereiten von mit heißem Wasser entwickelten Chromatgelatinereliefs für das galvanische Abformen, welches sich dadurch kennzeichnet, daß die Gelatinereliefs in die Chromverbindungen in der Gelatine unschädlich machenden Lösungen z. B. Bariumchlorid, Bleiacetat, gebadet werden, dann nach dem Trocknen mit Cellulosederivatlösungen, welche Cellulosederivate und Gelatine lösende Stoffe z. B. Essigsäure, enthalten, überzogen und durch Behandlung mit metallhaltigen Gasen oder Dämpfen, z. B. Nickelcaxb,onyldampf, stromleitend gemacht werden.In contrast, the present invention relates to a method for preparing chromate gelatin reliefs developed with hot water for the galvanic molding, which is characterized by the fact that the gelatin reliefs in the chromium compounds in the gelatine harmless solutions z. B. barium chloride, Lead acetate, to be bathed, then after drying with cellulose derivative solutions, which cellulose derivatives and gelatin dissolving substances z. B. acetic acid, contain, coated and treated with metal-containing gases or vapors, e.g. B. Nickelcaxb, onyl vapor, be made conductive.

Dadurch können nunmehr Gelatinereliefs mit bisher unbekannten Eigenschaften, insbesondere der Wahrung der Originaltreue, erzeugt werden. Dies geschieht dadurch, daß einerseits durch das erfindungsgemäße Vorbereitungsverfahren die Wasserunnlö.slichkeit und Quellunfähigkeit der Gelatinereliefs so gut wie vollkommen erreicht wird, anderseits eine elektrolytische Zerlegung der Beimengungen und die dadurch hervorgerufenen Formänderungen bzw. Zersetzung der Gelatine zufolge der bei der Galvanisierung auftretenden elektrischen Strömungsvorgänge nicht mehr eintreten können.As a result, gelatin reliefs with previously unknown properties, in particular the preservation of the faithfulness to the original. This is done by that on the one hand the water insolubility due to the preparation process according to the invention and the inability to swell of the gelatin reliefs is almost completely achieved, on the other hand an electrolytic decomposition of the admixtures and the resulting Changes in shape or decomposition of the gelatin as a result of those that occur during electroplating electrical flow processes can no longer occur.

Ein Ausführungsbeispiel des erfmrndungsgemäßen Verfahrens besteht darin, da.ß die Gelatinereliiefs nach dem Baden in Lösungen von Bariumchlorid, Bleiacetat o. dgl. und nach dem Trocknen mit Cellulosederivatlösungen, welche Cellulosederivate und Gelatine lösende Stoffe, z. B. Essigsäure, enthalten, überzogen werden.There is one embodiment of the method according to the invention in that the gelatine reliefs after bathing in solutions of barium chloride, lead acetate o. The like. And after drying with cellulose derivative solutions, which cellulose derivatives and gelatin solubilizers, e.g. B. acetic acid, are coated.

Ein derartiges überzugsbad kann zweckmäßig aus 5o ccm Eisessig, 5o ccm Nitrocelluloselösung 4%ig, 25 ccm Alkohol und 2o ccm Äther bereitet werden.Such a coating bath can expediently consist of 5o ccm of glacial acetic acid, 5o cc nitrocellulose solution 4%, 25 cc alcohol and 20 cc ether.

Zur Unterbindung der Wasseraufnahme und Quellfähigket bei gleichzeitiger Härtung der Gelatinereliefs können diese mit verdünnten Lösungen von Tetranitrocellulos.e, Dinitroaellulose o. dgl. in Gegenwart von Essigsäure o. dgl. behandelt werden. Nach: diesem Baden kann eine Nachhärtung der Gelatinereliefs z. B. mit einer 20%igen Formaldehydlösungerfolgen.To prevent water absorption and swellability at the same time Hardening of the gelatin reliefs can be done with diluted solutions of Tetranitrocellulos.e, Dinitroaellulose or the like in the presence of acetic acid or the like. Treated. To: This bathing can be a post-hardening of the gelatin reliefs z. B. be done with a 20% formaldehyde solution.

Das Stromletendmachen des so behandelten Gelatinereliefs erfolgt erfindungsgemäß durch eine Behandlung mit metallhaltigen Gasen oder Dämpfen, z. B. Nickelca.rbonyldampf, wodurch ein Niederschlag entsteht, der bis in die feinsten Poren der Reliefs abgeschieden wird.The gelatin relief thus treated is rendered current in accordance with the invention by treatment with metal-containing gases or vapors, e.g. B. Nickel ca.rbonyl vapor, This creates a precipitate that is deposited into the finest pores of the relief will.
