PROTEINACEOUS COLLOID COMPOSITIONS PROVIDED ON GLASS SUPPORTS

A photographic element comprising a glass support and a photosensitive emulsion layer on said support comprising a film-forming 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...

Beschreibung
Zusammenfassung:	A photographic element comprising a glass support and a photosensitive emulsion layer on said support comprising a film-forming 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.
