Abstract

1488080 Photographic development inhibitor releasing pyrazolone couplers FUJI PHOTO FILM CO Ltd 23 July 1975 [23 July 1974] 30874/75 Heading G2C [Also in Division C2] A silver halide emulsion, which may be supported together with other photographic layers, or a photographic colour developer alkaline solution, comprises a development-inhibitor releasing magentaforming coupler of the formula: wherein each of R1 and R2 independently represents an optionally substituted alkyl group, R3represents hydrogen or an optionally substituted alkyl, aryl or heterocyclic group, and R4 represents an optionally substituted alkyl, aryl or heterocyclic group. When employed in silver halide emulsions, the compounds advantageously contain a ballast group, i.e. a group containing a hydrophobic residue having 8-32 carbon atoms, and the emulsions may be spectrally sensitized. Further couplers may be added to the photographic compositions, as well as other conventional additives.
