发明名称 SILVER HALIDE COLOR PHOTOGRAPHING SENSITIVE MATERIAL
摘要 PROBLEM TO BE SOLVED: To provide a silver halide color photographic sensitive material containing a cyan coupler capable of obtaining good hue and enhancing image quality without deteriorating the sensitivity. SOLUTION: At least one layer formed on a support contains the coupler represented by the formula, in which Za is -C(R3 )= or -N= and when Za is -N=, Zb is -C(R3 )=, and when Za is -C(R3 )=, Zb is -N=; each of R1 and R2 is an electron withdrawing group having a Hammett' substituent constantσp of 0.20-1.00; R3 is a substituent; T is a bonding group to be released from the coupler by coupling with the oxidation product of a color developing agent and subsequently to be allowed to release an Ed part; (n) is 0 or 1; Ed is a group to be allowed to perform oxidation reduction reaction with the oxidation product of the color developing agent after being released from the coupler or Tb; and G is H atom or a blocking group to be released at the time of photographic processing.
