Description
Изображени на пр мокопирующих сло х, полученных путем импрегнировани бромосеребр ной или хлоросеребр ной (не содержащей растворимых солей серебра) эмульсий водно-спиртовыми растворами солей фенилгидразина и метола могут быть вирированы и фиксированы многими из примен емых в практике виражей и вираж-фиксажей. Наиболее пригодными вл ютс золотые виражи. Обычно примен емые вираж-фиксажи без золота (свинцовые) дают некрасивые тона и довольно значительное ослабление изображени . Однако красивые коричневые, с фиолетовым оттенком, тона можно получить и без применени золотых виражей.Images on the strapping layers obtained by impregnating bromide-silver or chloro-silver (not containing soluble silver salts) emulsions with water-alcohol solutions of phenylhydrazine and metol salts can be violated and fixed by many of the turns and twists-fixes used in the practice. The most suitable are the golden turns. The commonly used bend-fixes without gold (lead) give ugly tones and a rather significant weakening of the image. However, beautiful brown, with a violet tinge, tones can be obtained without the use of golden bends.
Предлагаемый способ состоит в том, что откопированный и промытый позитив погружают в слабый вод ной раствор йодистого кали . При обработке белые места копий принимают красивую кремовую окраску от образующегос йодистого серебра. Эту окраску можно несколько ослабить погрузив копию, после вирировани в слабомThe proposed method consists in that the copied and washed positive is immersed in a weak aqueous solution of potassium iodide. When processed, the white spots of the copies take on a beautiful cream color from the silver iodide that forms. This color can be somewhat weakened by immersing a copy, after virivating in a weak
растворе йодистого кали , на несколько секунд в крепкий раствор той же соли (20-40%-и). Концентраци йодистого кали в вираж-фиксажной ванне при первой обработке может колебатьс от 1 до lOVo. Перевод неразложившегос на свету бромистого серебра в йодистое фиксирует копию и делает ее неизмен ющейс на свету.potassium iodide solution for a few seconds in a strong solution of the same salt (20-40%). The concentration of potassium iodide in the turn-fixing bath during the first treatment can vary from 1 to lOVo. The conversion of undecomposed silver to silver in iodide fixes the copy and makes it unchanged from light.
