Cyan image forming method and silver halide color photographic material containing cyan coupler. |
摘要 |
<p>A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer containing at least one lH-pyrrolo[2,l-c][l,2,4]triazole cyan coupler represented by the following general formula (I) or (II): <CHEM> wherein R1, R2 and R3 each represents a hydrogen atom or a substituent, provided that at least one of R1 and R2 is an electron withdrawing group which has a Hammett's substituent constant sigma p value of 0.15 or more; R1 and R2 may be bonded to form a ring; and X represents a hydrogen atom or a substituent capable of being released upon coupling with an oxidation product of an aromatic primary amine color developing agent; said coupler may form a bis-compound or or a polymer at R1, R2, R3 or X; and a cyan image forming method comprising imagewise exposing a silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer and subjecting the exposed photographic material to color development with an aromatic primary amine color dveloping agent at the presence of the above-described lH-pyrrolo[2,l-c][l,2,4]triazole cyan coupler. <IMAGE></p> |
