cyanbilderzeugungsverfahren and cyankuppler containing farbphotographisches silberhalogenidmaterial

摘要

A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer containing at least one 1H-pyrrolo[1,2-b][1,2,4]triazole cyan coupler represented by the following general formula (I) or (II): CHEM wherein R1 and R2 each represents an electron withdrawing group having a Hammett's substituent constant sigma p value of 0.20 or more; R1 and R2 may be bonded to form a ring; the sum of a Hammett's substituent constant sigma p value of R1 and R2 is 0.65 or more; R3 represents a hydrogen atom or a substituent; 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 be in a form of a bis-compound or a polymer formed 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 1H-pyrrolo[1,2-b]-[1,2,4]triazole cyan coupler.
