Beschreibung
Zusammenfassung:	A silver halide photosensitive material is stabilized against overdevelopment fogging by containing at least one antifoggant thioether represented by the following general formula I in silver halide emulsion layer and/or layer contiguous to said emulsion layer; (I) wherein A represents the heterocyclic group of a mercapto antifoggant; R1 and R2, which may jointly form a benzene ring, represent each a halogen atom or an alkyl, aryl or aryloxy group.
