PURPOSE:To improve processing stability by incorporating a phenolic cyan coupler having an ureide group in the 2nd position into at least one layer of silver halide emulsion layers and incorporating the compd. expressed by the specific compsn. formula, etc., into the silver halide emulsion layer contg. said cyan coupler. CONSTITUTION:The silver halide photographic sensitive material having the silver halide emulsion layers on a base contains the phenolic cyan coupler having the ureide group in the 2nd position in at least one layer of the silver halide emulsion layers thereof. The compd. expressed by the formula I or the salt thereof is incorporated into the silver halide emulsion layer contg. said cyan coupler. In the formula, Y denotes an oxygen atom or sulfur atom; X denotes -NHCO(CH2)2COOH or -OC2H5 or -S(CH2)m-Z-OH (Z is CH2 or CO); (a), (b), (g) respectively denote 0 or 1 integer. (c) Denotes 0-3 integer; (d), (e) respective ly denote 0-2 integer; (f) denotes 2-6 integer; (m) denotes 1-6 integer and has >=3 sulfur atoms in the molecule. The example, of the formula I is shown by the formulas II, III. |
