Accordingly, the silver halide emulsion containing the compound and the photographic silver halide light-sensitive element having the silver halide emulsion layer of this invention are excellent in such points that the sensitivity is high and the formation of fog is less as compared with conventional emulsions and elements.
  • the compound of this invention may be added to a silver halide emulsion subjected to chemical ripening together with other additives as usually practiced or may be added to a silver halide emulsion subjected to physical ripening by a conventional method. However, better results can be obtained when the compound is added to a silver halide emulsion at the beginning of chemical ripening.
  • the amount of the compound shown above to be added to a silver halide emulsion is influenced by a desired effect, the degree of ripening thereof, the kind of the silver halide emulsion and the like, but in general, preferably about 2-100 g., particularly 5-50 g. of the 1,2-glycol are added per mole of silver halide in the emulsion.

  • the photographic silver halide emulsion containing the additive of this invention has a higher sensitivity and less fog than the control sample.
  • the photographic silver halide emulsion of this invention prepared above had a high sensitivity and gave less fog.
  • said compound is selected from the group consisting of 2,3-butanediol, 1,2-butanediol, pinacol, 1,2-h'exanediol, 1-phenyl-l,2-ethanediol, 3-m-octyl-oxyl ,2- propanediol, 3-aryloxy-l,2-propanedio1, 3-phenoxy-l,2- propanediol
