| titleOfInvention | METHOD OF MANUFACTURING BROMI-SILVER PHOTOGRAPHIC EMULSION WITH A SIZE OF MICRO CRYSTALS 1 - 2 MKM |
| abstract | A method of making silver bromide silver photographic emulsion with a microcrystal size of 1–2 μm by fractional single-jet emulsification by introducing into solution N1 containing potassium bromide, ammonium bromide, potassium iodide, gelatin and water, aqueous solution of ammoniated silver nitrate N2, pause and conduct N3 of ammoniated silver nitrate, containing 1.8-2.0 times more silver nitrate than solution N2, and the subsequent precipitation of the solid phase, washing the precipitate, dispersing, melting Effects with gelatin and chemical ripening, characterized in that, in order to reduce the optical density of the veil and silver deposition, in solution N1, potassium and ammonium bromides are used in an amount of 0.8 - 1.0 g-mole each per 1 g-mole of nitric acid silver in N2 solution, and before introducing the N3 solution into the emulsion, a solution of potassium and ammonium bromides is additionally introduced in an amount of 0.8-1.0 g-mole each for 1 g-mol of silver nitrate in N2 solution. |
