PURPOSE: To obtain a color photographic emulsion giving color photographic material small in fog, by incorporating silver chlorobromoiodide grains having a core/shell type structure consisting essentially of silver bromide and contg. silver bromide higher in the surface layer than in the inside together with a coupler. n CONSTITUTION: A silver halide emulsion consisting of 50W97mol% silver bromide, ≤2mol% silver iodide, and the rest of silver chloride, and having a core/ shell type structure contg. silver bromide higher in the surface layer than in the inside is prepared by mixing a mixture of aq. soln. of silver chloride, bromide, and iodide in each proportion corresponding to the intended compsn. of silver chlorobromoiodide. The intended silver halide photographic emulsion is obtained by adding cyan, magenta, and yellow couplers, a UV absorber, a fading inhibitor, and the like necessary additives to the obtained silver halide emulsion. n COPYRIGHT: (C)1984,JPO&Japio |
