ABSTRACT:
A silver halide photographic material having improved heat sensitivity comprises a red sensitive silver halide emulsion layer the silver halide of which is prepared in the presence of a hexacoordination complex of rhenium, ruthenium or osmium with at least four cyanide ligands and comprising at least about 90 mole percent silver chloride, wherein the emulsion contains at least one red sensitizing dye.
