Abstract

PURPOSE:To use a specific compound as a photographic magenta coupler which is superior in coloring speed and max. coloring density, does not produce photographic fogs and yellow stains and has stable coloring property with time. CONSTITUTION:The compound expressed by the formulaI(X, Y are oxygen, sulfur; Z is an atom group necessary for forming 5-7-membered rings; R1 is alkyl, aryl, heterocyclic ring; R2 is alkyl, alkylamino, cycloamino, heterocyclic amino, acylamino, anilino, ureido), for example, the formula II. The above- mentioned compound is used by adding the same as a coupler for forming magenta dye images in the constituting layer (more preferably green sensitive emulsion layer) of a photosensitive material at about 0.01-3mol ratios per mole of silver halide contained in its emulsion layer.
