PURPOSE:To enable a color image durable for long period storage to be obtained by incorporating a specified cyan dye forming coupler. CONSTITUTION:A silver halide photographic sensitive material contains at least one of cyan dye forming couplers represented by the formula in which R1, R3 are each independently an optionally substd. aliphatic, aryl, or heterocyclic group; R2 is an optionally substd. aliphatic or alkoxy group; Z is H or a group releasable by coupling; m, n are each 0 or 1, and when m and n are both 0, and both of R2 and R3 are each nonsubstd. alkyl, the total C number of them is >=3, or R1 is an optionally substd. aryl or heterocyclic group, and R2, R3 may be each a nonmetallic atomic group combining with each other and forming a 5--7-membered ring. |
