    摘要： The present invention relates to a process for manufacturing a silver halide photographic element comprising the step of adding to a silver halide emulsion (1) an aryl compound having at least two hydroxyl groups and at least one additional substituent represented by a sulfonic group, an alkali metal sulfonate group, an hydroxyl group, a carboxy group or an hydroxymethyl group and (2) a polyhydroxyalkyl derivative selected from the group consisting of non-hydrogenated polysaccharides having an average molecular weight higher than 10,000 and hydrogenated polysaccharides having an average molecular weight equal to or lower than 10,000. The use of such a combination to increase the speed to Dmin ratio of a silver halide photographic element and a silver halide element comprising such a combination is also claimed.

    摘要： A photographic element is disclosed having at least one emulsion layer comprised of (a) radiation-sensitive silver halide grains, (b) sensitizer for the radiation-sensitive silver halide grains, (c) hydrophilic colloid vehicle, including peptizer for the radiation-sensitive silver halide grains, and (d) light scattering particles, wherein (a) the radiation-sensitive silver halide grains include tabular grains (1) having an aspect ratio of at least 2.0, (2) having {111} major faces, (3) containing greater than 50 mole percent bromide, based on silver, and (4) accounting for greater than 50 percent total grain projected area, (b) the sensitizer includes a fragmentable electron donating sensitizer, (c) the peptizer is a water dispersible cationic starch, and (d) the light scattering particles have aspect ratios of less than 1.5 and can be dissolved for removal from the emulsion layer. The photographic elements exhibit enhanced imaging speed and can be employed for color or black-and-white photographic imaging.

    摘要： A silver halide photographic light-sensitive material is disclosed. The material comprises a light-sensitive silver halide emulsion layer and containing both of a latex stabilized by gelatin and a redox compound from which a development inhibitor is released when the redox is oxidized in the emulsion layer or other non-light-sensitive hydrophilic colloidal layer. The silver halide photographic light-sensitive material is suitable for graphic arts plate-making use and is excellent in Ming-Gothic type reproduction, screen-image enlarging and screen-image reduction aptitudes, white-on-color letter quality, paste-up trace prevention, easy handling and stability.
