 des zitronensauren Silbers ist auch das weinsaure anwendbar. Eine sehr gute Vorschrift   ist z. B. die folgende :

 ist. Mit dieser Emulsion hergestellte photographische Papiere zeigen folgende hervor-   ragende Eigenschaften :  
Sie sind ausserordentlich haltbar. In offenem Umschlage, ohne Umhüllung mit wasser-   dichtem Matcrial aufbewahrt,   zeigen sie auch nach vielen   Monaten keine Veränderung bei

     Vorstehende Beobachtungen,   besonders die geschilderte Entwickelbarkeit einer Silbersalx-Emulsion, die kein Halogensilber enthält, sind durchaus neu und   technisch   wertvoll, so dass sie als wesentlicher Fortschritt auf photochemischem Gebiete zu betrachten sind. 



  Die genannten Emulsionen sollen zur Herstellung lichtempfindlicher Schichten für Photographie benutzt worden.

 Using sions with the exclusion of the silver halide compounds did not produce a favorable result, as the gradation between the highest light and the lowest

 of the citric acid silver, the tartaric acid can also be used. A very good rule is e.g. B. the following:
 EMI1.4
 is. Photographic papers produced with this emulsion show the following excellent properties:
They are extremely durable. Stored in an open envelope without being wrapped in waterproof material, they show no change even after many months

     The above observations, especially the described developability of a silver salt emulsion which does not contain halogen silver, are entirely new and technically valuable, so that they can be regarded as an essential advance in the photochemical field.



  The emulsions mentioned are said to have been used to produce photosensitive layers for photography.
