PURPOSE:To improve the sharpness of the title material, and to obtain a cyan pigment picture having high optical density even at the time of processing the photosensitive material with a fatigued bleaching solution by incorporating at least one kind of coupler in which the max. absorption wavelength of the released pigment, etc., shifts to a short wavelength side before being released the pigment, and a specified coupler in the photosensitive material, respectively. CONSTITUTION:At least one kind of the coupler in which the max. absorption wavelength of the released pigment or the pigment formed from the precursor of said pigment shifts to the short wavelength side before being released the pigment, and at least one kind of the coupler shown by formula I are incorporated in the photosensitive material. In formula I, R<1> is -CONR<4>R<5> or -NHOR<4>, etc., R<2> and R<3> are each hydrogen atom or a substituting group, X is hydrogen atom or a group capable of being released by allowing it to react with the oxidant of an aromatic primary amine developing agent, (l) is 0 or 1, (m) is 0-3, R<4> and R<5> are each hydrogen atom or an aliphatic group. Thus, the sharpness of the photosensitive material at a high and a low frequency sides is improved, and the stable optical density of the cyan pigment picture is obtd., even at the time of processing the photosensitive material with the exhaused bleaching solution. |
