PURPOSE:To enhance spectral absorption characteristics by incorporating a 5-pyrazolone magenta coupler and a specified color-nonforming phenol compound in one of the constituent layers of a photosensitive material. CONSTITUTION:At least one of the constituent layers contains at least one of the 5-porazolone magenta couplers and at least one of the color-nonforming phenol compounds represented by formula I in which each of R1 and R2 is 1-24C straight or branched chain or cyclic alkyl, optionally same or different; lis an integer of 0-4; and when l is 2, 3 or 4, each of plural R2 may be same or different and the total carbon number of R1 and (R2)l is 20-54. |
