ABSTRACT:
A replenishing solution unit for color-developing a color photographic light-sensitive material is disclosed. The replenishing solution unit comprises at least (1) a replenishing solution containing a color developing agent and a sulfinic acid or a salt thereof and the pH of said replenishing solution is 2 to 6 and (2) a replenishing solution containing a replenishing solution component other than the color developing agent. The replenishing solution unit enables the preparation of a concentrated developing solution and has excellent storage stability over a long period of time without the decrease of photographic sensitivity and the increase of D.sub.min. A method for processing a color photographic light-sensitive material with the above replenishing solution unit is also disclosed.
