Abstract

Process for the preparation of a material for color photography, with at least one layer sensitive to light, characterized in that in its embodiment it comprises dissolving a yellow copulator of the general formula ** (see formula) ** In which G means a yellow copulant radical linked by the active methylenic group to heterocycle i, X means a nitrogen atom or an atom (linked to a hydrogen atom or a substituent) of carbon and means a hydrogen atom or a substituent, In an organic solvent or mixture of solvents, then form an emulsion with said solution and an aqueous solution of gelatin, possibly adjusting the ph of the emulsion to the usual values in the photographic technique, and combining said emulsion with the halide of silver also usual in this technique, finally extend the resulting emulsion on a support and dry to erase the hardening of the sensitive layer formed on said support.
