ABSTRACT:
A method for processing a silver halide color photosensitive material is disclosed.
The process step comprises developing a color photographic light-sensitive material composed of a support having thereon at least one light-sensitive silver halide emulsion layer containing a silver halide containing at least 80 mol % silver chloride; at least one emulsion layer thereof containing a dispersion of a mixture of (i) at least one oil-soluble non-diffusible cyan coupler capable of forming a substantially non-diffusible cyan dye by coupling with the oxidized form of a developing agent, and (ii) a water-insoluble polymer;
in a color developer solution comprising a primary amine color developing agent, and having a chloride ion concentration of from 3.5.times.10.sup.-2 to 1.5.times.10.sup.-1 mol/l, and a bromide ion concentration of from 3.0.times.10.sup.-5 to 1.0.times.10.sup.-3 mol/l.
When used in rapid processing methods, the method according to the invention prevents pressure-sensitization fogging, and provides high maximum density and low minimum density images.
