ABSTRACT:
A new process for maintaining the properties of the developer in the preparation of colored images by development of exposed silver halide-containing material at an alkaline pH in a developer bath containing p-phenylenediamine derivative and at least 40 mol-% of the silver halide consisting of silver chloride and replenishing the color developer in the bath in such a limited quantity that no overflow occurs but it is sufficient to make up for the loss of bath constituents.
This process preserves the sensitive results from development during use of the developer bath.
