ABSTRACT:
An aqueous photographic tri-color processing monobath, which includes a color developer and a fixing agent, and which has a pH of about 10.6, is capable of color developing and fixing an exposed photographic film, without requiring any bleaching of the developed film. Moreover, apparently due to the compact morphology of the residual silver, it has been discovered that a monobath of the type disclosed is suitable for producing both an unobscured dye image and a silver plus dye sound track in a single processing step.
