摘要： A process for producing a tabular silver halide emulsion by using a sulfur-containing silver halide solvent that promotes growth of silver halide grains, and a light-sensitive material containing the emulsion are disclosed. The grain growth effect of the silver halide solvent is reduced or eliminated by using an oxidizing agent thereby excluding the adverse effect of the silver halide solvent upon chemical ripening.

The process comprises color developing an exposed light-sensitive material in the presence of a compound of the general formula: ##STR1## wherein M is a hydrogen atom, an alkali metal atom, NH.sub.4 or a protective group for the mercapto group which undergoes cleavage by the action of an alkali; R is a hydrogen atom or an alkyl group containing 1 to 3 carbon atoms; and R' is a hydrogen atom or an alkyl group containing 1 to 3 carbon atoms. This process prevents the formation of color development fog without seriously reducing sensitivity.
