Abstract

PURPOSE:To obtain an superior image with high sharpness free from fog and stain by adding a specified 5-pyrazolonemagenta coupler so as to maintain the color developing property of a photosensitive material even after long-term storage. CONSTITUTION:To a photographic emulsion layer is added a 2-equiv. magenta forming biscoupler represented by the formula (where R is acylamino, anilino or ureido, Ar is optionally substituted phenyl, the substituent is >=1 halogen, alkyl or alkoxy, Y is a phenylene bond, an ether bond, a sulfone bond, an ester bond, a thioether bond or a simple bonding radical, and each of X and Z is 1-30C alkylene or alkenine). The resulting photosensitive material maintains the color developing property and high stability even after long-term storage at high temp. and humidity. It has high color developing density, does not cause heat stain and fog, and shows high developing activity.
