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 synthetic substrate used for quantitative analysis of a trace enzyme. The substrate has a molecular structure (B)-(A)-(C) comprising at least one structure (A) catalytically affected by the enzyme to be analysed, at least one photographically active labelling structure (B) linked to the structure (A) and at least one specific adsorbing structure (C) linked to the structure (A). The substrate is used in a quantitative analysis of a trace enzyme, in which the structure (A) or the linkage between the structure (A) and the structure (C), or the linkage between the structure (B) and the structure (A) is cleaved by the action of the analyte enzyme. The reaction product of the enzymatic reaction is separated by allowing the same to contact with an adsorbent for the structure (C). The separated reaction product is developed photographically and then the optical density of the resultant developed silver and/or colored dye is measured.
