Abstract
Process for forming yellow dye images in silver halide photographic material using 2-equivalent .alpha.-pivaloyl acetanilide couplers having at the 5-position a ballasting sulfonyl amido group.
Claims13
A process for forming yellow dye images comprising developing an imagewise exposed light-sensitive silver halide photographic material with a developer containing an aromatic primary amine type developing agent in the presence of a yellow coupler represented by the following general formula (I):
- ##STR15## wherein R.sup.1 represents a hydrogen atom or an alkyl group, aryl group or heterocyclic group, which may individually have a substituent, X represents an alkylene, arylene, aralkylene or divalent organic group represented by the following general formula (II) -A-V-B- which may individually have a substituent, Y represent an alkyl group;
- aryl group or heterocyclic residue, which may individually have a substituent, Z represents a non-metal atomic group necessary for forming in cooperation with --CO--N--CO-- a 5- or 6-membered ring,
- wherein A and B individually represent an alkylene, a arylene or aralkylene group, which may individually have a substituent, and V represents a divalent linking group.
A photographic material having a light sensitive silver halide emulsion layer coated on a support wherein the material contains a yellow coupler represented by the following general formula (I):
- ##STR17## wherein R.sup.1 represents a hydrogen atom or an alkyl group, aryl group or heterocyclic group, which may individually have a substituent, X represents an alkylene, arylene, aralkylene or divalent organic group represented by the following general formula (II), -A-V-B- which may individually have a substituent, Y represent an alkyl group, aryl group or heterocyclic residue, which may individually have a substituent, Z represents a non-metal atomic group necessary for forming in cooperation with --CO--N--CO-- a 5- or 6-membered ring,
- wherein A and B individually represent an alkylene, arylene or aralkylene group, which may individually have a substituent, and V represents a divalent linking group.
