Farbige Bilder mit von der Luftfeuchtigkeit beeinflusstem Farbenwechsel.
Die Eigenschaft einer Anzahl von Metallverbindungen (z. B. Chlorkobalt, Chlorkupfer, Chlornickel, essigsaurem Kobalt, salpetersaurem Nickeloxydul) bei Erhöhung des Feuchtigkeitsgehaltes der Luft ihre Farbe zu verändern, ist bekannt : desgleichen deren Anbringung auf Gelatinoscbicbten (siehe z. B. D. K. P. Nr. 28F) 20), um diese Wirkung auch bei niedrigeren Temperaturen zu erzielen. Diese Schichten wurden jedoch bisher nur auf der Vorderseite der das Bi) d tragenden Unterlage angebracht, was den wesentlichen Übelstand hatte, dass die bei feuchtem Wetter klebrig werdende Schicht abrann, mindestens aber beim Anfassen verwischt oder abgewischt wurde.
Den Gegenstand vorliegender Erfindung bildet eine derartige Anordnung des Bildes und der Metallsalzschicht, dass keine der Schichten verletzt

raum gewährleistet. Bei Anwendung einer solchen zweiten Platte kann die Anordnung von Bild und Salzschicht verschieden getroffen werden. Am zweckmässigsten erscheint es wohl, dass die Vorderplatte dem Beschauer die Glasseite zuwendet und deren Rückseite das mit Farben versehene Bild trägt, während die Rückplatte innen die Metallsalzschicht trägt und auf der anderen Seite mattiert ist. Doch kann auch die Vorderseite der Vorderplatte das Bild tragen, die Rückseite die Salzschicht und die zweite Platte mattiert sein oder umgekehrt.
Man kann sogar noch eine dritte Platte anwenden und die Schichten zwischen diesen beliebig kombinierren, immer aber unter Wahrung des Grundsatzes, dass die die Salzschichte tragende Plattenseite innen liegt und durch die übrigen Platten unter Wahrung

Colored pictures with color changes influenced by the humidity.
The property of a number of metal compounds (e.g. chlorocobalt, chlorocopper, chlorine nickel, acetic acid cobalt, nitric acid nickel oxide) to change their color when the moisture content of the air increases is known: the same is true of their application to gelatin labels (see e.g. BDKP No. 28F ) 20) to achieve this effect even at lower temperatures. However, these layers have so far only been applied to the front of the base carrying the image, which has the major disadvantage that the layer, which becomes sticky in damp weather, ran off, but was at least smeared or wiped off when touched.
The subject of the present invention is such an arrangement of the image and the metal salt layer that none of the layers is damaged

space guaranteed. When using such a second plate, the arrangement of the image and salt layer can be made differently. It seems to be most expedient that the front plate faces the viewer with the glass side and the back side bears the picture provided with colors, while the back plate bears the metal salt layer on the inside and is matted on the other side. But the front of the front plate can also carry the picture, the back the salt layer and the second plate can be matted or vice versa.
You can even use a third plate and combine the layers between these as desired, but always while maintaining the principle that the plate side carrying the salt layer is on the inside and through the other plates under preservation
