Abstract

PURPOSE:To use a specific compond 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[R1 is alkyl, aryl, heterocyclic group; R2 is alkyl, alkoxy, amino, acylamino, anilino, ureido; A is substituted alkyl (substituents are nitrile, carboxyl, aldehyde, thiocarbonyl, silyl, nitro); n is 1-5 integers], 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.
