Zusammenfassung: | PURPOSE:To provide the above material having a good preservable property by spectrally sensitizing silver halide photographic emulsion layers with cationic and tricarbocyanine dyes and incorporating specific compds. into the silver halide photographic emulsion layers and/or other hydrophilic colloidal layers. CONSTITUTION:The silver halide photographic emulsion layers are spectrally sensitized by the cationic and tricarbocyanine dyes and at least one of the compds. expressed by formulas (I to III) are incorporated into the silver halide photographic emulsion layers and/or the other hydrophilic colloidal layers. In formula I, R4 to R6 denote a hydrogen atom, 1 to 12C alkyl group, etc.; in formula II, R7 to R9 denote a hydrogen atom, halogen atom, etc,; R10 denotes a phosphoric acid group, etc.; In formula III, R11 and R12 denote a hydrogen atom, hydroxyl group, etc.; R13 denotes a phosphoric acid group, etc. The deterioration in the sensitivity by the resting and stagnating of the emulsion coating liquid is prevented in such a manner and the preservable property of the photosensitive material with the lapse of time is improved. |
