    摘要： PROCESS OF REPRODUCTION USING A RECORDING LAYER CONTAINING HEXACYANOFERRATE (III) IONS AND A SUBSTANCE PROVIDING IONS OF SELECTED METALS, PREFERABLY AN N-TYPE PHOTOCONDUCTOR. THE LAYER IS EXPOSED TO AN ELECTROMAGNETIC RADIATION IMAGE REDUCING THE HEXACYANOFERRATE (III) IONS IN THE EXPOSED REGIONS TO HEXACYANOFERRATE (II) IONS. THE EXPOSED LAYER IS DEVELOPED BY CONTACTING UNIFORMLY WITH AN AQUEOUS DEVELOPING SOLUTION CONTAINING A DYE INTERMEDIATE WHICH IS OXIDIZABLE INTO A DYE. THE HEXACYANOFERRATE (III) IONS IN THE UNEXPOSED REGIONS OXIDIZE THE DYE INTERMEDIATE AND ARE IN TURN REDUCED TO HEXACYANOFERRATE (II) IONS WHICH COMBINE WITH THE METAL IONS TO FORM A PRECIPITATE HAVING A STRONG AFFINITY FOR THE DYE OXIDATION PRODUCT. IF THE EXPOSURE IS THROUGH A POSITIVE ORIGINAL, A POSITIVE COPY IS OBTAINED SINCE THE IMAGE AREAS OF THE ORIGINAL SHIELD THE CORRESPONDING AREAS OF THE RECORDING LAYER FROM EXPOSURE. A LAYER CONTAINING PHOTOCONDUCTIVE ZINC OXIDE IS ESPECIALLY PREFERRED.

    摘要： A photographic element comprising a glass support and a photosensitive emulsion layer on said support comprising a filmforming proteinaceous colloid is described. The adherence of the emulsion layer to the glass support is enhanced by including the emulsion layer an organic silicon compound having hydrocarbon groups directly or indirectly attached to a silicon atom wherein at least one of the hydrocarbon groups carries a group or atom which has chemical affinity for the free reactive groups of the proteinaceous colloid or which can be cross-linked to the free reactive groups through the intermediary of a cross-linking agent. The adherence of the photosensitive emulsion layer to the glass support is enhanced without affecting the photosensitive properties of the emulsion layer.
