发明名称 Silver halide color photographic material
摘要 A silver halide color photographic material comprising at least one layer provided on a support, said layer containing a coupler represented by the following formula (1): <IMAGE> (1) wherein Za represents -C(R3)= or -N=; Zb represents -C(R3)= when Za is -N= or Zb represents -N= when Za is -C(R3)=; R1 and R2 each represents an electron attractive group having a Hammett substituent constant sigma p of 0.2 to 1.0; R3 represents a substituent; T represents a linking group which can be released from the coupler by coupling thereof with an oxidized color developing agent and can subsequently release an ED moiety; n represents 0 or 1; the ED moiety represents a group which can be released from the coupler or T to undergo a redox reaction with the oxidized color developing agent; and G represents a hydrogen atom or a blocking group which can be eliminated from the coupler on photographic processing, whereby good hues and high image quality can be attained without any sensitivity decrease.
