PURPOSE:To improve the sensitivity of a color photosensitive material, and to increase the desilvering of the material by incorporating two kinds of specified couplers in the sensitive material. CONSTITUTION:The sensitive material comprises a compd. (FR) capable of being released a coupler or a development accelerator or its precursor (FA) by allowing it to react with the oxidant (a) of an aromatic primary amine developing agent, and a compd. (BAR) capable of releasing a bleach-accelerating agent (its precursor) by allowing it to react with the oxidant (a). And, the (FR) compd. is composed of a coupler, etc. capable of releasing the (FA) compd. or a color matter acting as the (FA) compd. And, the (BAR) compd. is composed of a coupler shown by the formula, etc. In the formula, A is a group capable of being released with the oxidant (a), T1 and T2 are each a binding group, B is a group capable of being released the binding between groups B and T2 with the oxidant (a), Z is a group having bleach-accelerating ability, (l)-(n) is each 0-1. |
