Photographic silver halide emulsion

Abstract

Abstract PURPOSE:To obtain a photographic silver halide emulsion with extra-low sensitivity by blending silver halides contg. >=90mol% silver chloride, also blending a water- soluble rhodium salt, and adding a compound represented by a specified general formula. CONSTITUTION:Silver halides contg. >=90mol% silver chloride are blended, a water-soluble rhodium salt is also blended, and a compound represented by formula I is added to prepare a photographic silver halide emulsion. The amount of the compound of formula I added is preferably 0.2-2g per one mole silver halides, and that of the rhodium salt 10<-3>-10<-5>mol per one mole silver halides.
