Abstract
Abstract A method of stabilizing a light-sensitive silver halide coior photographic material is disclosed in which the developed silver halide color photographic material is treated with a dye stabilizing solution comprising a soluble iron sait at a concentration of at least 1 x 10 -4 mol/l, said solution having a pH from 3.0 to 9.0, following the last stage in the color processing of said photographic material.
