PURPOSE:To enlarge the allowable region of the titled material in a fogging exposure by incorporating a silver halide particle, at least one kind of a nitrogen contg. heterocyclic compd. contg. a mercapto group and at least one kind of a specified compd. in the titled material. CONSTITUTION:The titled material contains the silver halide particle having a clear layer structure and at least one kind of the nitrogen contg. heterocyclic compd. contg. the mercapto group, and at least one kind of the compd. shown by formula I wherein R11 and R12 are each alkyl group, R13 is hydrogen atom. or aryl group, etc., R14 and R15 are each hydrogen atom. or alkyl group, (a) is 0 or 1, Z11 and Z12 are each a benzotiazole or a naphthothiazole group, etc., X is an anion, (b) is 0 or 1. Thus, the effect of enlarging the allowable region of the titled material in the fogging exposure is obtd. |
