M 131540 KLASSE 57b. M 131540 CLASS 57b.

Die Herstellung photographischer Schmelzfnrbenbilder geschieht bisher in folgender Weise:The production of photographic melt images has so far been done in the following way:

Eine Schicht von Gelatine, Zucker, Dextrin und dergl. und Bichromat, z. B. Kaliumbichromat, wird unter einem Positiv belichtet und durch Einstauben mit verglasbaren Farben, die nur an den unbelichteten Stellen haften bleiben, entwickelt, hierauf zur Entfernung des unzersetzten Bichromate, das beim Einbrennen stören würde, mit Säure gewaschen, auf den zu decorirenden Gegenstand übertragen und eingebrannt. Da derartige Schichten aber wegen ihres lockeren Zusammenhanges leicht zerstörbar sind und durch den Waschprocefs, namentlich an den farbehaltigen, also nicht belichteten Stellen, sehr gefährdet werden, so mufs man die Schicht vor der Waschung durch eine oberflächlich aufgetragene Collodiumschicht verstärken. A layer of gelatin, sugar, dextrin, etc., and dichromate, e.g. B. potassium dichromate, is exposed under a positive and by dusting with vitrifiable colors that only stick to the unexposed areas, developed, then to remove the undecomposed Bichromate, which would interfere with baking, washed with acid, on those to be decorated Object transferred and branded. Since such layers are easily destructible because of their loose connection are and by the washing process, namely on the color-containing, i.e. not exposed Places that are very endangered must be applied through a layer before washing Reinforce the collodion layer applied on the surface.

Der Erfinder versuchte diese Verstärkung dadurch entbehrlich zu machen, dafs er das CoI-lodium direct der lichtempfindlichen Mischung zusetzte. Es gelang auch, das Collodium der wässrigen Lösung von Bichromat und Honig, Stärkezucker, Dextrin und dergl. direct ohne Zersetzung zuzusetzen, wenn die Lösung vorher mit Alkohol versetzt wurde und möglichst wenig Wasser enthielt, so dafs sie eine syrupartige Consistenz besafs.The inventor tried to make this reinforcement superfluous by using the colodium added directly to the photosensitive mixture. It was also possible to use the collodion aqueous solution of bichromate and honey, starch sugar, dextrin and the like. Directly without Add decomposition if alcohol has been added to the solution beforehand and if possible contained little water, so that it had a syrupy consistency.

Das Verfahren wird z. B. folgendermafsen ausgeführt:The method is e.g. B. carried out as follows:

Für ι 1 der Mischling löst man 1 g Bichromat in 30 bis 40 ecm heifsem Wasser, mischt dieser heifsen Lösung 3 g Honig bei und setzt dem Ganzen L/2 1 Alkohol von 990 zu. Man erhält auf diese Weise eine Lösung von Bichromat in Alkohol von etwa 91°. In diese alkoholhaltige Mischung schüttet man 1J2 1 normales Collodium.For ι 1 Mongrel 1 g bichromate is dissolved in 30 to 40 cc of hot water, this torrid solution mixed with 3 g of honey and sets the whole L / 2 1 alcohol of 99 to 0. In this way, a solution of bichromate in alcohol of about 91 ° is obtained. 1 J 2 1 normal collodion is poured into this alcohol-containing mixture.

Die nach dem neuen Verfahren hergestellten lichtempfindlichen Mischungen werden wie gewöhnlich auf Platten aufgetragen und in der üblichen Weise behandelt. Eine Verstärkung der Schichten ist nicht erforderlich. Vielmehr sind diese so widerstandsfähig, dafs sie den Waschprocefs auch in grofsen Stücken ohne jede Beschädigung aushalten.The photosensitive mixtures prepared by the new process are as usual applied to plates and treated in the usual way. It is not necessary to reinforce the layers. Much more these are so resistant that they can be used even in large pieces without the washing process withstand any damage.

Ein weiterer durch die vorliegende Erfindung gebotener Vortheil besteht darin, dafs man nach dem neuen Verfahren mehrfarbige Abzüge in Schmelzfarben herstellen kann. Ohne dafs es nothwendig ist, die über einander geschichteten Häutchen aus Collodium und Bichromat zu übertragen, genügt es, sie nach jeder Lichteinwirkung und Ueberstäubung durch eine Gelatine- oder Gummischicht zu isoliren.Another advantage offered by the present invention is that one can produce multicolored prints in enamel colors using the new process. Without that it is necessary that the layers of collodion and bichromate are layered on top of one another it is sufficient to transfer them after each exposure to light and over-dusting by a To isolate gelatine or rubber layer.

Diese Isolirschicht verhindert, dafs der in 'der neu aufgetragenen Schicht enthaltene Alkohol beim Auftragen eines neuen Häutchens auf das bereits entwickelte das Bild zerstört.This insulating layer prevents the alcohol contained in the newly applied layer when a new membrane is applied to the already developed one, the image is destroyed.

Das Verfahren eignet sich besonders zur directen Erzeugung der Bilder auf dem zu decorirenden Gegenstand ohne Uebertragung.The method is particularly suitable for the direct production of the pictures on the thing to be decorated Object without transfer.
