PURPOSE:To obtain a silver halide photographic sensitive material permitting extremely quick processing by constituting the material of an emulsion contg. flat silver halide particles having >=3 mean aspect ratio and incorporated with a spectral sensitizing dye having >=99mol.% total content of AgCl+AgBr, and giving a specified hardening effect to the emulsion. CONSTITUTION:A silver halide photographic sensitive material contg. flat particles of AgCl, AgBr, AgBrCl, or AgIBrCl having >=3 mean aspect ratio and spectrally sensitized with at least one spectrally sensitizing dye expressed by the formulas I-VI in the emulsion layer, wherein 70-200min time is required for causing dissolution of a hydrophilic colloid layer by the photosensitive dye, is prepd. By this constitution, a silver halide photographic sensitive material having covering power for silver of high sensitivity and high developability permitting extremely quick processing so quick as <=45sec (Dry to dry) is obtd. |
