Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
83 words
A method for processing an exposed color photographic material which comprises on a support (1) at least one of hydrophilic coloidal layer one of which layer containing a silver halide emulsion and a coupler, and (2) a color developing agent or a precursor thereof in the hydrophilic layer, wherein the exposed color photographic material is developed in a color developer containing a color developing agent which color developer is replenished with a replenisher containing 0 to 0.016 mol/l of a color developing agent.
Claim 2
Independent Claim
83 words
A method for processing an exposed color photographic material which comprises on a support (1) at least one of hydrophilic coloidal layer one of which layer containing a silver halide emulsion and a coupler, and (2) a color developing agent or a precursor thereof in the hydrophilic layer, wherein the exposed color photographic material is developed in a color developer containing a color developing agent which color developer is replenished with a replenisher containing 0 to 0.016 mol/l of a color developing agent.
Claim 3
Dependent Claim
37 words
A method according to claim 1 wherein the color photographic material contains a color developing agent or precursor thereof in an amount at 0.01 to 4.0 times of as much as the silver halide on molar basis.
Claim 4
Dependent Claim
32 words
A method according to claim 1 wherein the color developing agent or precursor thereof is contained in a layer located adjacent to the layer containing a silver halide emulsion and a coupler.
