摘要： A process for the development of color photographic light-sensitive material is described. 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.

摘要： A process for preparing a silver halide photographic emulsion to be used for a photographic material is provided. Therein, additives such as dyes, sensitizers, auxiliary agents to be used upon gold sensitization, and so on are utilized within a period from at the silver halide grain forming time to just before the emulsion coating, and oxidizing agents are added at the time when the functions of the additives become substantially needless to result in conversion of the additives to those having no bad influences on photographic characteristics of the emulsion prepared, or to those having such chemical structures as to facilitate their removal with a washing treatment or the like.Silver halide emulsions prepared by the described process are also disclosed.
