ABSTRACT:
A color diffusion transfer photographic element comprising a support having provided thereon a layer containing a dye-providing material associated with a light-sensitive silver halide emulsion, wherein said dye-providing material is a metal chelate compound represented by the following general formula (I) or (II): ##STR1## wherein M.sup.I represents a monovalent, divalent, or trivalent cation; X represents a monovalent, divalent, or trivalent anion; Z and Z.sup.2 each represents an aromatic carbon ring nucleus or heterocyclic ring nucleus having 5 to 7 carbon atoms; G represents a chelating group; Z.sup.1 represents an aromatic carbon ring nucleus or heterocyclic nucleus composed of 5 to 7 atoms; said nucleus having (a) a nitrogen atom, or (b) a carbon atom bonded to a chelating group at the position adjacent to the position bonded to the azo group; Z.sup.3 represents an electron attractive group; Z.sup.4 represents an alkyl group, an aryl group, or a substituted amino group; L represents a ligand including a dye ligand; M.sup.II represents a metal ion weakly coordinated to the dye ligand moiety as compared with the metal ion contained in the image-receiving layer; and p, r and n each is an integer of 0 to 5 and q is 1, 2 or 3 and take a combination that the charges of the total chelate dyes become zero, wherein the chelate compound further contains (1) a carrier component losing the diffusible property or (2) a ballasted carrier capable of releasing a diffusible dye when the silver halide emulsion is developed under an alkaline condition.
