    摘要: Colored cyan couplers corresponding to formula II are eminently suitable for masking the yellow secondary density of cyan dyes. The reproduction of blues and yellows is thus improved. The colored cyan couplers of formula II are preferably used together with phenolic cyan couplers bearing a phenylureido group in the 2-position and an acylamino group with a ballast group in the 5-position ##STR1## In formula II: CC represents a cyan coupler group to the coupling position of which L is attached;L is a bifunctional connecting group;Q.sup.1, Q.sup.2 represent H or photographially inert substituents;R represents a coupling component such that the compound of formula II is a yellow dye. ##STR2## in which R.sup.3 is alkyl, aryl, carboxyl, carbamoyl, acylamino, anilino;R.sup.4 is H, alkyl, aryl, a heterocyclic group;R.sup.5, R.sup.6 (same or different) represent -CO-alkyl, -CO-aryl, -CO-alkoxy, carbamoyl, -CN;represents O, S, NH;Z is the group required to complete a 5- or 6-membered carbocyclic or heterocyclic ring.

    摘要: 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.
