Abstract
A color developer composition that maintains developer activity in all color forming layers and increases developer capacity is disclosed. The color developer composition allows use of reduced temperature, process time, replenishment rate, or concentration of developing agent without causing color imbalance. The composition employs two or more different color developing agents in combination. Each agent in a composition is selected from the group consisting of p-amino-N-dialkylanilines and the salts thereof. The composition of the present invention may be employed in conventional color developing processes without any significant change in conventional processing procedures and steps.
