摘要： A process for the production of a photographic image which comprises(a) imagewise exposing a photographic assembly which comprises at least during a silver halide developing step, in order optionally a supercoat layer, at least one silver halide emulsion layer, a layer containing a layer substantive hydroxypyridone azamethine compound of the general formula ##STR1## wherein R.sub.1 is hydrogen or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl, amino or heterocyclic radical, Y represents hydrogen or hydroxy, --CN, --COOR.sup.1, --CONR.sup.1 R.sup.2 or --COR.sup.1 or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical and Z is hydrogen or is --CN, --COOR.sup.3, --CONR.sup.3 R.sup.4, --SO.sub.3 H, --SO.sub.3.sup.- or --COR.sup.3, where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each independently represent hydrogen or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, and E represents the atoms necessary to complete an optionally substituted heterocyclic or aromatic ring, and a support, there being optionally one or more interlayers between each of said components,(b) treating the exposed photographic assembly with an aqueous alkaline processing bath, containing a silver halide developer and(c) in the non-latent image areas, allowing the silver halide developer to diffuse in a counter-imagewise manner from the silver halide emulsion layer(s) to the layer containing the compound of formula (1) and there to bleach the compound to form a photographic dye image.The developers used in this process exhibit an increased stability against oxidizing agents.
