摘要： A method for forming photographic color images is disecond closed, in which a silver halide color photographic light-sensitive material is rapidly processed with low replenishment of processing solutions. The images improved in lowered yellow stain can be obtained. The processing comprises steps of color developing, bleaching immediately after the developing step, and treating with a bath having a fixing capability following the bleaching step. The steps of bleachin and treating with a solution having a fixing capability are carried out for a time of not more than 3 minutes 45 second at a temperature of from 20 to 45 DEG C. The light-sensitive material comprises silver halide emulsion layers each containing silver bromide and/or silver boromoiodide grains and satisfies at least one of the following requirements (1) and (2); (1) a blue light-sensitive emulsion layer included in the silver halide emulsion layers has a silver density d of not less than 4.0x 10 g/cm . (2) a green light-sensitive emulsion layer included in the silver halide emulsion layers has a silver density d of not less than 6.0x 10 g/cm . T

摘要： A photographic material comprising at least one blue sensitive silver halide emulsion layer is disclosed. The silver density of the emulsion layer is not less than 4.0x10-1 g/cm3 and the dry thickness of the layer is not more than 4.0 mu m. A core/shell type silver halide emulsion and a high-speed reaction type scavenger for the oxidation products of a developing agent are preferably used for the emulsion layer. The photographic material has a high sensitivity and provides an image having a superior sharpness and resolution.

摘要： A silver halide color photographic light-sensitive material comprises a support and at least one light-sensitive layer. This layer has a plurality of silver halide emulsion layers substantially identical in color sensitivity, but differing in speed. The light-sensitive layer is comprised substantially of monodispersed silver halide emulsions A and B, each containing silver halide particles of the core/shell-type. The silver halide particle sizes of emulsions B and A have a ratio, when multiplied by 100, of less than 70 and the silver halide particles of emulsion B have a silver iodide content in their core that is not less than 5 mole % smaller than that of the core of the silver halide particles of emulsion A.

摘要： PURPOSE:To improve surface smoothness and to improve heat resistance by incorporating at least one kind of compds. which are the coupling reaction product of a specific precursor compd. and the oxidant of a color developing agent and are substantially colorless into picture elements of at least one color. CONSTITUTION:At least one kind of the compds. which are the coupling reaction product of the specific precursor compd. expressed by formula I and the oxidant of the color developing agent and are substantially colorless are incorporated into the picture elements of at least one color. In the formula I, R0 denotes =4C alkyl group or cycloalkyl group; R2 denotes a halogen atom, cyano group, sulfamoyl group, etc.; n denotes 0 to 5 integer; plural R2 may be same or different when n is >=2. The precursor compd. expressed by the formula I is preferably incorporated into a coupler-in-developer type developing soln. or a black and white developing soln. for silver dye bleach processing. A color developing agent is incorporated therein in the case of the black and white developing soln. The surface smoothness is improved in this way and the color reproducibility is upgraded.
