 EMI1.1 
 



   Wie bekannt, werden   Eiweissstoffo   durch mineralsaure Salze wie z. B. sapetersaures Silber koaguliert. Diese Eigenschaft ist jedoch nur für das   getrennte Präparationsverfahren     \') n Heleutung,   z. B. für das Verfahren nach dem   österr.   Patent   Ni.'26678   der Protalbinwerke in Dresden oder nach dem D. R. P. Nr. 144296 der Firma Dr. buss & Cie. in 
 EMI1.2 
 werden. Es beziehen sich diese Patente also nur auf Verfahren der   getrennten Präparation   sowie Befestigung der Schicht auf der Unterlage durch verschiedene Salze, wie Halogensalze, salpetersaures Silber usw., sind somit keine Emulsionsverfahren. Eine Ausnahme 
 EMI1.3 
   angesäuert   und mit 100 cm3 milchsaurem Silber 1 : 10, emulsioniert. 



   11. In 1000 cm3 Wasser werden in der Wärme 80 g Zitronensäure und 80 9 Kasein gelöst   und   mit 100 cm3 milchsaurem Sibler 1 : 10 emulsioniert. 



   Eine ander herstellungsart der Emulsion ist folgende : Kasein wird durch salpeter-   saures Silber gefätit und das   entstehende   Kaseinsilber   in verdünnter organischer Säure gelöst, z. B. 80 g Kaseïnsilber wird in   1000 cm3 80/0 Zitronensäurelösung   gelöst. Diese   Lösung kann sowohl allein, als   auch mit 150 cm3 milchsaurem Silber 1 : 10 emulsioniert, verwendet werden. 



   Anstatt   milchsaurem   Silber können auch Silbersalze anderer organischer Säuren, wie 
 EMI1.4 
 wendung kommen.

 EMI1.1
 



   As is known, Eiweissstoffo by mineral acid salts such. B. sapeterate silver coagulated. However, this property is only relevant for the separate preparation process, e.g. B. for the method according to the Austrian patent Ni.'26678 of the Protalbinwerke in Dresden or according to the D. R. P. No. 144296 of the company Dr. Buss & Cie. in
 EMI1.2
 will. These patents therefore only relate to processes of separate preparation and attachment of the layer to the substrate by means of various salts, such as halogen salts, silver nitric acid, etc., and are therefore not emulsion processes. An exception
 EMI1.3
   acidified and emulsified 1:10 with 100 cm3 of lactic acid silver.



   11. 80 g of citric acid and 80 g of casein are dissolved in 1000 cm3 of water and emulsified 1:10 with 100 cm3 of lactic acid Sibler.



   Another way of producing the emulsion is as follows: Casein is filled with nitric acid silver and the resulting casein silver is dissolved in dilute organic acid, e.g. B. 80 g of casein silver is dissolved in 1000 cm3 of 80/0 citric acid solution. This solution can be used alone or emulsified 1:10 with 150 cm3 of lactic acid silver.



   Instead of lactic acid silver, silver salts of other organic acids, such as
 EMI1.4
 turn come.
