ABSTRACT:
A color development process for processing an imagewise exposed silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer comprising a color coupler and a silver iodobromide emulsion containing silver iodide in an amount of from 2 to 20 mol %, comprising the step of processing the color photographic material in a color developing solution containing a color developing agent and bromide ion for 40 seconds to 90 seconds, wherein the color developing agent is represented by formula (D'): ##STR1## wherein R.sub.1d, and R.sub.2d, each represents an alkyl group having 1 to 4 carbon atoms; and L.sub.1 represents a straight-chain or branched alkylene group having 3 or 4 carbon atoms, the concentration {Br.sup.- } of bromide ion in the color developing solution is from 30 to 60 mmol/l, the relationship between the concentration {R} of the color developing agent in the color developing solution and the concentration {Br.sup.- } of bromide ion in the color developing solution and the relationship between the development processing temperature Tem and the concentration {Br.sup.- } of bromide ion are maintained to satisfy a Rule defined by the following equations: {R}=((0.63.times.{Br.sup.- })+(14)).+-.16 (mmol/l); Tem=((0.19.times.{Br.sup.- })+(39)).+-.5 (.degree.C.), where {R} is the concentration of color developing agent in units of mmol/l; {Br.sup.- } is the concentration of bromide ion in units of mmol/l; and Tem is the development processing temperature in .degree.C.
