Abstract
A photographic processing solution for processing a silver halide color photographic light-sensitive material and a processing method using the same is disclosed. The photographic processing solution comprises formaldehyde and an amine compound having at least one --NH-- group in the --NH-- equivalent amount per liter of the photographic processing solution being greater than the molar concentration of formaldehyde in the photographic processing solution. The photographic processing solution is stable and has a reduced formaldehyde vapor pressure. The processing method provides excellent image stability.
