| titleOfInvention | METHOD FOR PRODUCING HALOGEN-SILVER PHOTOGRAPHIC EMULSION |
| abstract | 1. A method of manufacturing a silver halide photographic emulsion by the method of controlled two-jet crystallization by introducing a solution of silver nitric acid and a solution of potassium bromide into the emulsion and adding iridium ions in the crystallization process, characterized in that the two-stream injection of solutions is interrupted for the period of introduction of iridium ions. ! 2. The method according to claim 1, characterized in that the two-stream injection of solutions is interrupted for a period of 30-120 s before injection and exposure 30-120 s after the introduction of iridium ions. ! 3. The method according to claim 1 or 2, characterized in that the complex compounds of the group are used as iridium ions: K2 [IrBr6] (potassium hexabromoiryridate), K2 [IrCr6] (potassium hexachloroiridate), K2 [IrBr5Cl] (potassium chloropentabromoiridate) K2 [IrCr5Br] (potassium bromopentachloroiridate). ! 4. The method according to claim 1 or 2, characterized in that the iridium ions are introduced in an amount of from 10-7 to 10-9 mol / mol of silver. |
