Abstract (en)
[origin: WO9517701A1] The present invention concerns a process for obtaining a silver halide photographic emulsion which can be used in colour negative photographic processes. This emulsion comprises grains containing a silver chlorobromide core and a peripheral area with a high silver chlorobromide content, and is chemically and spectrally sensitised. This emulsion has improved sensitivity characteristics.
