ABSTRACT:
A redox-amplification solution comprising hydrogen peroxide, or a substance capable of releasing hydrogen peroxide, or reducing agent, such as a color developing agent, and in combination three or more sequestering agents for complexing with a transition metal ion to inhibit catalysis of impurities emanating from a photographic film coating and enhance the stability of the solution; a method of photographic color processing including a step using the redox-amplification solution and its use therefor.
