PURPOSE:To decrease the fluctuation in photographic characteristics at the time of continuous processing by specifying the amt. to be replenished of the color developing soln. contg. a specific compd. to 20-120ml per 1m<2> photographic sensitive material. CONSTITUTION:The compd. expressed by the formula I is incorporated into the color developing soln. and the amt. of the color developing soln. to be replenished is specified to 20-120ml per 1m<2> photographic sensitive material. The compd. expressed by the formula I is used by being incorporated preferably at 0.5-10g in 1l color developing soln. in this case. In the formula, R<1>-R<3> denote a hydrogen atom., alkyl group, aryl group or heterocyclic group; R<4> denotes a hydrogen atom., hydroxy group, hydrazino group, alkyl group, aryl group, heterocyclic group, alkoxy group, aryloxy group, carbamoyl group or amino group; X<1> denotes a bivalent group; n denotes 0 or 1. The change of the photographic characteristics at the time of the continuous processing is thereby decreased. |
