Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
149 words
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 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.
Claim 2
Dependent Claim
