Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ ГАЛОГЕНСЕРЕБРЯНЫХ ФОТОГРАФИЧЕСКИХ ЭМУЛЬСИЙ Пример 2. К мелкозернистой желатиновой хлорбромсеребр ной эмульсии, примен емой дл полива цветных пленок (получают из 0,455 г-моль/л бромистого аммони , 0,086 г-моль/л йодастого кали , 0,05 г-моль/л хлористого натри , 0,422 /л азотнокислого серебра и 3,5 г/л желатины) добавл ют 10%-ньш раствор осадител (из расчета 0,29 на 1 г желатины), довод трН до 3,7-4,0 уксусной кислотой, с образовавшегос осадка удал ют жидкую фазу декантацией, промывают осадок холодной водой, диспергируют в желатиновом растворе и провод т второе созревание. Пример З.К мелкозернистой позитивной эмульсии (получают из 0,326 г-моль/л бромистого кали , 0,007 г-моль/л йодистого кали , 0,286 г-моль/ азотнокислого серебра и 4,5 г желатины)(54) METHOD OF MANUFACTURING HALOGEN-SILVER PHOTOGRAPHIC EMULSIONS Example 2. To a fine-grained gelatin chlorobromide-silver emulsion used for watering color films (prepared from 0.455 g-mol / l ammonium bromide, 0.086 g-mol / iodine, iyastast, 0.086 g-mol / iodine, iyastast, 0.086 g-mol / l ammonium bromide, 0.086 g-mol / iodine, iyastast, 0.086 g-mol / l iodine, Iyastast, 0.086 g-mol / l ammonium bromide, 0.086 g-mol / l iyastropy, 10yyool, 0.086 gmol / l ammonium bromide; mol / l sodium chloride, 0.422 / l silver nitrate and 3.5 g / l gelatin) 10% precipitator solution (at the rate of 0.29 per 1 g gelatin) is added, the trN ratio is up to 3.7-4.0 acetic acid, with the precipitate formed, the liquid phase is removed by decantation, the precipitate is washed with cold water, dispersed in a gelatinous solution, and ripening is carried out second. Example Z.K fine-grained positive emulsion (prepared from 0.326 g-mol / l potassium bromide, 0.007 g-mol / l potassium iodide, 0.286 g-mol / silver nitrate and 4.5 g gelatin)
