Definitions
- the primary object of our invention is to provide J- an* improved light-sensitive photographic z silverhalide emulsion.
- A- more specic object is, to provide a lightsensitive photographic emulsion having a supersensitizing quality. It is known to increase the spectral sensitivity of a photographic emulsion by simultaneously using a sensitizing dyestuihwhich'.
- a still further object is to provide a photographic element comprising a support coated with l such a supersensitiaed emulsion.
- D representsnon-metallic atoms necessary to complete a heterocyclic 5- or o-membered ring
- R represents alkyl, aryl or aralkyl
- the main sensitizer and supersensitizer may simultaneously be added to the emulsion; or the coated light-sensitive emulsion already containing the main sensitizer may be bathed in a solution of the supersensitizer; or the non-sensitized emulsion layer may be bathed in a mixture of the two sensitizers. Finally, the supersensitizer may be added to the anti-stress layer or to the barite layer.
- the light-sensitive emulsion may be prepared with the help of any binder known in the photographic emulsion technique, e. g., gelatine and vinylpolymers.
- R. represents alkyl, aryl, aralkyl
- X represents a member selected from the group consisting of halogen and an acid residue
- n a positive integer
- Y represents aryl
- X represents a monovalent group selected from the group consisting of alkyl and hydrogen
- X represents an alkyl group
- D represents the nonnetallic atoms necessary-to complete a member selected from the group consisting of heterocyclic -membered and het- ⁇ erocyclic -membered rings,
- R represents alkyl, aryl, aralkyl
- X represents a member selected from the group consisting of halogen and an acid residue
- D represents the non-metallic atoms necessary to complete a member selected from the group and as a supersensitizer alphamercapto-iso valerio acid p-chloroanilide.
- D represents the non-metallic atoms necessary to 20 complete a member selected from the group 6 consisting of heterocyclic -membered and heterocyclio -rnembered rings,
- R represents alkyl, aryl, aralkyl, R and R represent alkyl
- X represents a member selected from the group consisting of halogen and an acid residue
- n represents a positive integer
