A method for manufacturing a silver halide emulsion comprising core/shell type silver iodobromide grains, said emulsion having an average iodide content of 3 mol % or more, each of the grains having two or more phases different in silver iodide content from each other which comprises an inner phase having silver iodide content of 10 mol % or more and an outermost phase having a silver iodide content lower than the iodide content of the inner phase, wherein a compound represented by the following formula [I] is present at least in a process prior to a desalting process:

Method of manufacturing a silver halide emulsion

A light-sensitive silver halide color photographic material is disclosed. The color photographic material is stored in roll, and has a value of ##EQU1## being 20 to 60 .mu.m, wherein at least one silver halide emulsion layer contains a silver halide emulsion containing silver chrolide in a proportion of not less than 10 mol %. The photographic material is excellent in resistant to pressure desensitizing and preventive from producing scratching trouble. A photographic unit containing the photographic material is also disclosed.

Silver halide color photographic light sensitive material stored in roll

A silver halide color negative photographic light-sensitive material is disclosed which is improved on stability to fluctuation of processing conditions applied thereon, and has a sufficient wide exposure latitude. The photographic material is also improved on standing stability of silver halide emulsion in the course of manufacturing thereof. The photographic material comprises a support having thereon photographic component layers including at least one silver halide emulsion layer containing at least two groups of silver halide grains each being substantially different in desensitizing agent content from each other.
