  Selbsttonendes photographisches Papier. 



   Keine der bisher vorgeschlagenen goldhaltigen Kompositionen zur Herstellung von selbsttonendem Papier hat in   genügendem   Grade das erwünschte Resultat ergeben, das goldhaltige Tonbad überflüssig zu machen und einen echten haltbaren Goldton zu erzeugen, gleichzeitig   aber ein haltbares und leicht@ benutzbares Papier zu liefern. Mag   das Gold in der Form von Oxyd, Nitrat, Sulfat, Rhodanid oder, wie es am häufigsten der Fall gewesen,    < n der Form von Chlorid   benutzt werden (vgl. die engl. patentschriften Nr. 6651 u. 15352 vom Jahre 1896 u.

   Nr. 6609 vom Jahre 1901 und die deutschen Patentschriften Nr. 67016,   771     (i2, 110089 und 132421),   die Komposition weist entweder zu geringe Beständigkeit während der Aufbewabrung des Papieres auf, oder sie reagiert zu langsam im Wasserbad.   oder die Reaktion   (die   Tönung)   verläuft nicht wie sie sollte. Selbst wenn ein wirklicher   ( ; oldlol1 in   einzelnen Fiillen erreicht wird, ist er so schwach, dass er während der Warm-   satinierung   ganz oder   teihveise verschwinden   kann.

  Self-toning photographic paper.



   None of the previously proposed gold-containing compositions for the production of self-toning paper has sufficiently produced the desired result of making the gold-containing clay bath superfluous and producing a real, durable gold tone, while at the same time providing a durable and easily usable paper. May the gold be used in the form of oxide, nitrate, sulfate, rhodanide or, as it was most often the case, in the form of chloride (cf. the English patents No. 6651 and 15352 from 1896 and 1896).

   No. 6609 from 1901 and the German patents No. 67016, 771 (i2, 110089 and 132421), the composition either has too little resistance during storage of the paper or it reacts too slowly in the water bath. or the reaction (tint) is not going as it should. Even if a real (; oldlol1 is achieved in individual cases, it is so weak that it can completely or partially disappear during the warm satin finish.



   The present invention now relates to a self-toning one. Paper that is not durable on its own and is a real one when you dive into a saltwater or similar bath

 delay of the toning process, whereby a greater evenness of the effect is achieved. Accordingly, it is used in the manufacture of the photographic paper

 Paper in an astonishingly short time and with the greatest security. Depending on the salinity of the bath, the tone can range with perfect accuracy from reddish brown to
 EMI1.3
