| titleOfInvention | Photographic phenolic couplers with amido coupling-off groups |
| abstract | A photographic coupler represented by the following formula (I) [A] - NHCOR (I) wherein A represents a cyan color forming coupler residue having a naphthol nucleus or a phenol nucleus; the RCONH-group is a substituted in the coupling position of [A], and R represents (1) an aliphatic hydrocarbon or alicyclic hydrocarbon group which has at least one electron attractive substituent in the alpha -position to the carbonyl group in the RCONH- group, or (2) an aryl group, a heterocyclic group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an acyl group or an amino group which may be substituted with one or more electron attractive substituents, and R as defined by (1) or (2) above is a residue of a carboxylic acid of the formula RCOOH having a pKa of about 1.3 or less; a photographic light-sensitive silver halide emulsion containing the photographic coupler; and a method of forming images comprising developing an exposed photographic light-sensitive silver halide emulsion in the presence of the photographic couplers. |
