摘要： PURPOSE:To improve the whiteness of non-image area and the sharpness of an image by interposing a mordanting layer of a polymer contg. monomeric units each having a protonic ammonium group and further contg. monomeric units each having an acidic group convertible into an anionic group in an aq. alkali soln. of a specified pH or above between a support and a silver halide emulsion layer. CONSTITUTION:When a photosensitive silver halide emulsion layer is formed on a reflective support, at least one mordanting layer of a polymer contg. monomeric units each having a protonic ammonium group and further contg. monomeric units each having an acidic group convertible into an anionic group by proton dissociation in an aq. alkali soln. of pH >=9.0 is interposed between the support and the photosensitive layer. Superior whiteness is obtd. and the sharpness of an image and the tone reproducibility of the detail of the highlight can be improved.

摘要： PURPOSE:To enable rapid processing of color development and to obtain a high picture image density by processing a silver halide color photosensitive material with a developing soln. having ca.8-13 pH and contg. an aromatic primary amine type color developing agent and N,N-dihydroxylamine as antioxidant under a specified condition. CONSTITUTION:A silver halide color photosensitive material is processed with a developing soln. having ca.8-13 pH and contg. an aromatic primary amine type color developing agent and N,N-di[(un)substituted lower alkyl] hydroxylamine as antioxidant under a condition that no 1-aryl-3-pyrazolidone deriv. having two substituents in a 4-position is present. Preferred example for the aromatic primary amine type color developing agent is p-phenylene diamine deriv. Thus, color photographs having always high picture image density are obtd. because there is no change in the photographic characteristic against lapse of time and the developing agent has high preservability. Moreover, precipitates are not generated in the color developing soln. and an suspended matters are generated therein.
