Abstract
A method for forming a cyan dye image by developing an exposed silver halide photographic material with a developer containing a color developing agent in the presence of a cyan coupler, wherein the coupler is a 2,5-diacylaminophenol in which each acylamino group has a substituent containing an oxycarbonyl, sulfonyloxy, oxysulfonyl, arylsulfonamide or arylsulfamoyl group or other organic group containing a sulfone group.
Claims17
A method for forming a cyan dye image by developing an exposed silver halide photographic material with a developer containing a color developing agent in the presence of a cyan coupler, wherein the cyan coupler is a 2,5-di-acylaminophenol in which each of acylamino group has a substituent containing an oxycarbonyl, sulfonyloxy, oxysulfonyl, arylsulfonamide or arylsulfamoyl group or other organic group containing a sulfone group.
A photographic material having a silver halide emulsion layer coated on a support which layer comprising a cyan coupler of a 2,5-diacylaminophenol in which each of acylamino group has a substituent containing an oxycarbonyl, sulfonyloxy, oxysulfonyl, arylsulfonamide or arylsulfamoyl group or other organic group containing a sulfone group.
