Production process of silver halide photographic emulsion and silver halide photographic light-sensitive material |
摘要 |
A process for producing a (spectrally sensitized silver halide photographic emulsion having high sensitivity is provided. A process for producing a silver halide photographic emulsion comprising as a sensitizing dye at least one connection dye having two or more chromophores connected through a covalent bond, the process comprising adding said connection dye to a silver halide photographic emulsion and allowing at least one chromophore out of a plurality of chromophores in the molecule of the connection dye to change in the adsorption strength to a silver halide grain; and a process for producing a silver halide photographic emulsion comprising a silver halide grain having adsorbed on the surface thereof a sensitizing dye in multiple layers, the process comprising adding one or a plurality of sensitizing dye(s) to said silver halide emulsion and allowing at least one sensitizing dye out of added sensitizing dyes to change in the adsorption strength to a silver halide grain.
