Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A development method for an image-wise exposed light-sensitive silver halide photographic material which comprises developing, by a developing agent, the photographic material in the presence of a compound represented by the following formulas: ##STR36## wherein R 1 and R 1 ' are individually hydrogen, halogen, hydroxyl, or a substituted or unsubstituted alkyl, aralkyl, alkenyl, amino, aryl or acryl group; R 2 and R 2 ' are individually hydrogen, hydroxyl, or a substituted or unsubstituted alkyl, aralkyl, alkenyl, aryl, hydrazino, heterocyclic, alkylthio or aralkylthio group; R 3 , R 3 ', R 4 , R 4 ', R 5 , R 5 ', R 6 and R 6 ' are individually hydrogen, alkyl, aryl or a heterocyclic group; and A is a divalent atomic group said compound being present in the material or in a developer bath of the developer composition.
Claim 2
Dependent Claim
