    • Novel compounds are disclosed which have the formula
      wherein A is a phenyl moiety or a naphthyl moiety; B is a 4'-oxo-1'-phenyl moiety or a 4'-oxo-1'-naphthyl moiety and X is a non-nucleophilic group that cannot add to the central carbon atom but in alkaline solution undergoesan irreversible cleavage reaction with base to provide a nucleophilic moiety that adds to the central carbon atom to form a ring-closed compound which is colourless. The compounds may be included in photographic products comprising a support, at least one photosensitive silver halide emulsion layer and a layer containing the coloured compound and during development of such products with an aqueous alkaline processing composition the group X cleaves to form a ring closed colourless compound.
