PURPOSE:To improve the decoloring property of the subject material due to processing, and the aging stability, the color reproducibility and the sharpness of the photosensitive material by incorporating a specified dyes and a specified coupler in the photosensitive material. CONSTITUTION:At least one kind of the dye shown by formula I and at least one kind of the coupler shown by formulas II and III are incorporated in the photosensitive material. In the formula, X and X' are each hydrogen atom or hydroxyl group, etc., Y and Y' are each hydrogen atom or alkyl group, etc., Z and Z' are each hydrogen atom or cyano group, etc., L1-L5 are each methine group, (l) and (m) are each 0-1, (n) is 1-3, M<n+> is (n) valent cation, R<31> is alkyl group, etc., R<32> is acylamino group, etc., R<33> is hydrogen atom, etc., Z<31> is a group capable of being released by allowing it to react with hydrogen atom, etc., R<34> is alkyl group, etc., R<35> is acyl group, etc., R<36> is hydrogen atom, etc., (p) is 0-1, Z<31> is a group capable of being released by allowing it to react with hydrogen atom, etc. Thus, the photosensitive material which has a low fog and the excellent sharpness and color reproducibility is obtd. |
