Formation of color photographic image with azo dye containing alkoxy or thioalkoxy metal chelating group

摘要

A method for the formation of a color photographic image comprising exposure and development of a photographic element, said photographic element comprising at least one silver halide emulsion layer, a compound capable of releasing a diffusible azo dye compound during development, and at least one mordant layer arranged on a support. The color image formation is effected by the reaction of multivalent metallic ions with an azo dye compound having the formula: <IMAGE> (I) wherein G1 is an alkoxy or a thioalkoxy metallic chelating group; G2 is a metallic chelating group in which an oxygen atom is involved in the chelate formation; and Z1 and Z2 each is a group of atoms necessary to form an aromatic carbocyclic ring or a heterocyclic ring. The azo dye compound and the metallic ions form a metal complex by coordination of the azo group and the G1 and G2 groups of the azo dye compound with the multivalent metallic ions.
