Low replenishment color development using chloride ion-free color developer concentrate

Abstract

An aqueous, homogeneous, single-part, chloride ion-free color developing concentrate comprises a color developing agent in free base form, an antioxidant for the color developing agent, a buffering agent, and a water-miscible or water-soluble hydroxy-substituted, straight-chain organic solvent present in an a concentration such that the weight ratio of water to the organic solvent is from about 15:85 to about 50:50. Upon dilution at least four times, this composition can be used to provide a color developing composition for processing photographic color papers. The same concentrate can also be diluted to provide a replenisher for the color developing composition that is used at a replenishment rate of from about 50 to about 150 ml/m.sup.2 of processed color paper.
