  Verfahren zur Herstellung von unentflammbarem, durchsichtigem Film. 



   Vor kurzem wurde als Ersatz für gewöhnlichen   Zelluloidfjm   eine unentflammbare Schicht vorgeschlagen, die erhalten wird durch die Vereinigung der Zelluloseazetate mit den Estern oder Thioestern der Phenole, Kresole oder   Naphtole   oder deren Derivate,
Es wurde nun gefunden, dass die gemischten Zelluloseester wie die Sulfazetate, die Phosphate usw. der Zellulose für die Fabrikation von   unentflammbaren   Films von grossem Wert sind, wenn man sie mit den Estern oder Thioestern der Phenole usw. vereinigt.

   Dadurch, dass die Löslichkeit der Doppelester eine bedeutend höhere ist, als die der   Z (illulosea,. etate   und dadurch, dass man Lösungen erhalten kann mit praktisch verwertbaren Lösungsmitteln wie Azeton   usw.,   wird die Fabrikation des Films, insbesondere im unendlichen Bande, ausserordentlich erleichtert. Für die Praxis ist die Fabrikation die gleiche, aber viel vorteilhafter, als die bekannte. 



    PATENT-ANSPRÜCHE :  
1. Verfahren zur Herstellung unentflammbarer durchsichtiger Bildträger für photographische und andere Zwecke, dadurch gekennzeichnet, dass gemischte Zelluloseester mit den Estern der Phenole, Kresole oder Naphtole oder deren Substitutionsprodukten nach bekannten Vorfahren verarbeitet werden. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of non-flammable, transparent film.



   Recently, a non-flammable layer has been proposed as a substitute for ordinary celluloid film, which is obtained by combining the cellulose acetates with the esters or thioesters of phenols, cresols or naphthols or their derivatives,
It has now been found that the mixed cellulose esters such as the sulfacetates, the phosphates, etc. of cellulose are of great value for the manufacture of non-flammable films when they are combined with the esters or thioesters of phenols, etc.

   Because the solubility of the double esters is significantly higher than that of the Z (illulosea, etate, and because solutions can be obtained with solvents that can be used in practice, such as acetone, etc., the production of the film, especially in the infinite band, is extraordinary In practice, the manufacture is the same, but much more advantageous than the known one.



    PATENT CLAIMS:
1. Process for the production of non-flammable transparent image carriers for photographic and other purposes, characterized in that mixed cellulose esters are processed with the esters of phenols, cresols or naphthols or their substitution products according to known ancestors.

** WARNING ** End of DESC field may overlap beginning of CLMS **.

Ausführungsform des Verfahrens nach Anspruch l, dadurch gekennzeichnet, dass an Stelle der Ester die Thioester der Phenolc, Kresole oder Naphtole oder deren Substitutionsprodukte verwendet werden. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 2. Embodiment of the method according to claim l, characterized in that the thioesters of phenols, cresols or naphthols or their substitution products are used instead of the esters. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
