摘要： PURPOSE:To enable rapid processing and to obtain a dye image having a sufficiently small min. density by specifying the total silver quantity of the silver halide to be incorporated into blue-, green- and red-sensitive silver halide emulsion layers and the pH of a processing soln. having a bleaching power. CONSTITUTION:The silver halide particles of >=90mol.% silver chloride content and a magenta coupler having and the pH of the processing soln. having the bleaching power is specified to 4.5-6.5.
