ABSTRACT:
A process of obtaining highly stable color masking dyes comprises use of an element which has a support having thereon at least one silver halide emulsion layer having associated therewith an essentially colorless, immobile, ligand-releasing compound of the structure LIG-X. In this structure, X is a group which, as a function of silver halide development, is cleaved from LIG, and LIG is a ligand capable of complexing with metal ions while joined to X to form a color masking dye. A color masking dye is formed by developing the imagewise exposed areas of the described element with a developing agent to cleave LIG from X and washing substantially all of the cleaved LIG moieties in those areas out of the element, and treating the element with metal ions to form a masking dye complex with LIG-X in unexposed areas.
