摘要： Disclosed is a silver halide photographic emulsion containing tabular silver bromide series grains having a mean aspect ratio of 2 or more, which is characterized by the grains having no projection on the grain surface and by the silver chloride content in the surface part of the grains being higher than that in the part of the grain which is underneath the grain surface. Also disclosed is a multi-layer photographic light-sensitive material having at least two silver halide emulsion layers on a support in which at least one of the silver halide emulsion layers contains the tabular silver bromide series grains as defined above. By the incorporation of the emulsion, the sensitivity, the storage stability and the manufacture stability properties of the photographic material are improved without deteriorating its graininess property.
