PURPOSE:To obtain the title material which has the remarkably less deterioration of photographic characteristics during the preservation of the photosensitive material, and the excellent aptitude of rapid processing at a high temp. and is capable of sensitizing by near infra red rays and has the high sensitivity by mounting an emulsion layer contg. a silver halide particle which is prepared in the presence of a specified sensitizing color matter, on a supporting body. CONSTITUTION:The emulsion layer contg. the silver halide particle which is prepared in the presence of the sensitizing color matter shown by formula I at the time of forming the silver halide particle is mounted on at least one surface of the supporting body. In formula I, Z1 is a nonmetal atomic group necessary for forming a benzthiazole nucleus or a benzoxazole nucleus, etc., Z2 is a nonmetal atomic group necessary for forming a benzthiazole nucleus, R1 and R2 are each 1-4C alkyl, a substd. alkyl or aryl group, X<-> is an anion, (n) is 1 or 2. Thus, the title photographic sensitive material which is prevented the generation of a fog at the time of preserving the material and has the high sensitivity and the stable performance is obtd. |
