Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
98 words
A method for processing of a silver halide photographic material which comprises carrying out stabilizing processing of a silver halide photographic material directly with a liquid stabilizer substantially without passing through the step of washing with water subsequent to the desilverization processing step, wherein processing is conducted while at least one of (i) contacting the liquid stabilizer with an ion-exchange resin or (ii) at least a part of the overflow liquid stabilizer after contacting the ion-exchange resin is used as the liquid stabilizer to prevent yellow stains in the photographic material immediately after processing or during storage thereafter.
