Method of forming a photographic dye image

A method of forming a photographic azo or azomethine dye image in an exposed photographic silver halide element, the method comprising the steps of

• (a) developing the imagewise exposed material to form an imagewise pattern of oxidized color developing agent,
• (b) reacting the oxidized color developing agent with a color coupler to produce an image dye,
• wherein both the color developing agent and the color coupler possess at least one metal chelating site such that the image dye is capable of forming a tri- or higher-dentate metallized dye, and
• wherein the color developing agent is hydrazide of the formula:
• ##STR143## wherein R.sup.5 is substituted or unsubstituted alkyl, aryl or heterocyclyl,
• X.sup.2 is --N.dbd. or ##STR144## X.sup.3 is --CO-- or --SO.sup.2 --, Z.sup.3 represents the atoms necessary to complete an aromatic carbocyclic or heterocyclic nucleus, and
• G is a metal chelating group, a salt thereof, or a hydrolyzable precursor thereof, and,
• (c) contacting the image dye with polyvalent metal ions to form a metallized dye image.

• R.sup.1 is alkyl of 1 to 4 carbon atoms,
• R.sup.2 is an unsubstituted or substituted or substituted alkyl or aryl,
• R.sup.3 is hydrogen or R.sup.2, and
• Z.sup.1 represents the atoms necessary to complete a diffusible or non-diffusible coupler capable of forming a non-diffusible azo or azomethine dye on coupling with oxidized color developing agent;
• and,
• (c) contacting the image dye with polyvalent metal ions to form a metallized dye image.

A method of forming a photographic azo dye image in an exposed photographic silver halide element, the method comprising the steps of

• (a) developing the imagewise exposed material to form an imagewise pattern of oxidized color developing agent, then
• (b) reacting the oxidized color developing agent with a color coupler to produce an azo image dye,
• wherein at least the color developing agent possesses at least one metal chelating site such that the azo image dye is capable of forming a bi-, tri- or higher-dentate metallized dye, and
• wherein the color developing agent is a hydrazide of the formula:
• ##STR149## wherein R.sup.5 is substituted or unsubstituted alkyl, aryl or heterocyclyl,
• X.sup.2 is --N.dbd. or ##STR150## X.sup.3 is --CO-- or --SO.sup.2 --, Z.sup.3 represents the atoms necessary to complete an aromatic carbocyclic or hereocyclic neculeus, and
• G is a metal chelating group, a salt thereof, or a hydrolyzable precursor thereof, and,
• (c) contacting the azo image dye with polyvalent metal ions to form a metallized dye image.
