Abstract
Disclosed is a silver halide photographic material. The material comprises a support and at least one emulsion layer, wherein the emulsion layer includes a silver chlorobromide emulsion. The silver chlorobromide emulsion has been obtained by chemically sensitizing de-salted silver chlorobromide grains in the presence of a nucleic acid or degradation product thereof at a pAg value ranging from about 6.5 to 7.5. The silver chlorobromide grains have been obtained by subjecting the surface of silver halide grains to halogen conversion, which silver halide grains are essentially silver iodide free and have a plurality of phases of which the halogen compositions substanially differ from each other.
