The process of forming a dye image by developing an image-exposed silver halide photographic emulsion layer by an aromatic primary amine color developing agent in the presence of the yellow dye forming coupler shown by the general formula ##STR1## wherein R.sup.1 represents an aromatic group, R.sup.2 represents an aromatic group or a heterocyclic group, and Z represents the non-metallic atom or atoms necessary for forming a 4-membered ring, a 5-membered ring or a 6-membered ring together with ##STR2## in the above formula. A photographic element containing such a yellow-forming coupler.

Process of forming yellow photographic images

A method of forming color photographic images which comprises developing image-exposed photographic silver halide emulsion layer with a primary aromatic amino color developing agent in the presence of a yellow color forming coupler represented by the following general formula (I) ##STR1## wherein X.sub.1 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group or an acyl group; X.sub.2 represents a hydrogen atom, an alkyl group or an aryl group; X.sub.3 represents a hydrogen atom, an alkyl group, an aryl group or an acyl group; Y represents an oxygen atom or a sulfur atom; and Q represents a residue of a yellow color forming coupler, e.g., a yellow coupler in which one hydrogen atom attached to the active methylene group of the coupler is eliminated. These yellow color forming couplers provide yellow color images having superior properties.
