摘要： PURPOSE:To make the time from the completion of exposure to processing very short by containing a specific compound in a silver halide photosensitive material, and starting the development processing within preset seconds after exposure. CONSTITUTION:A silver halide photosensitive material provided with at least one layer of a silver halide emulsion layer on a base contains a compound expressed by the formula, and the development processing of the silver halide photosensitive material is started within 15sec after exposure. In the formula, R -R indicate alkyl group, alkenyl group, or allyl group, R is hydrogen atom, alkyl group, alkenyl group, or aryl group, and (n) is an integer of 1-3. R may be the same or different when (n) is 2-3, and R is alkyl group, alkenyl group, or aryl group when (n) is 1. The silver halide photosensitive material is preferably processed with a coloring developer having its replenishment quantity of 20-60ml for the silver halide photosensitive material of 1m .

摘要： PURPOSE:To improve color reproducibility, light resistance and yellowing resistance by using specific magnetic couplers and specific compd. CONSTITUTION:Polyethylene (PE) is laminated on one surface of a paper base. The PE contg. titanium oxide is then laminated on another surface. Further, a protective layer contg. gelatin, a UV absorbent layer, a red sensitive layer contg. a red sensitive silver chlorobromide emulsion and cyan coupler, etc., a UV absorbent layer, a green sensitive layer contg. a green sensitive silver chlorobromide emulsion and magenta coupler, etc., an intermediate layer, and a blue sensitive layer contg. a blue sensitive silver chlorobromide emulsion and magenta coupler, etc., are applied thereon. The photosensitive material is thereafter subjected to color developing, bleach fixing, stabilizing, and drying after exposing in accordance with the conventional method. The general formulas of the couplers incorporated into these photosensitive emulsion layers are expressed by formulas [M-I] or [C-I] and the compd. expressed by general formula [II] is incorporated into at least any one layer of the photosensitive emulsion layers or nonphotosensitive emulsion layers.
