Abstract: Photographic elements having a protective coating or photosensitive layer with improved viscosity characteristics and improved conductivity are provided by incorporating into a gelatin containing coating selected hydrophilic polymers and a soluble inorganic fluoride salt. The elements thus improved conventionally contain a support, one or more photographic silver halide layers and one or more protective layers. This improved composition may be, for example, a conventional silver halide emulsion formulated with gelatin and including the sodium salt of polystyrene sulfonate and ammonium fluoride, or a conventional protective overcoat composition with gelatin, the usual coating aids and hardeners and including the potassium salt of polystyrene sulfonate and ammonium silico fluoride.
