Description
По вление черных и белых точек на про вленных светочувствительных сло х чаще всего св зано с попаданием мельчайших частиц метаь лов (CuFe) в эмульсионный слой или на нодлолску.The appearance of black and white dots on the developed photosensitive layers is most often associated with the ingress of the smallest particles of metals (CuFe) into the emulsion layer or into Nodalol.
Предлагаемый способ полива фотографических светочувствительных галоидосеребр ных .слоев устран ет указанный недостаток тем, что в эмульсию перед поливом ввод т этилендиаминтетрауксусную кислоту или ее соли с щелочными металлами.The proposed method of irrigating photographic photosensitive halide-silver layers eliminates this disadvantage in that ethylenediaminetetraacetic acid or its salts with alkali metals are introduced into the emulsion prior to irrigation.
Пример. Эмульсию «Рентген-Х-1 со всеми необходимыми добавками , обычно вводимыми при поливе, расплавл ют и на две равные части. Перва часть остаетс как контрольна , а во вторую добавл ют 20%-вый раствор двунатриевой соли этилендиамннтетрауксусной кислоты в количестве 10 мл на 1 кг эмульсии. Оба образца эмульсии затем поливают в лабораторной поливной машине на основу, на которую предварительно нанос т мелкие опилки железа. После сущки изготовленные образцы пленки про вл ют в про вителе «Рентген в течение 8 минут, а затем фиксируют, промывают « сушат.Example. The X-1 X-1 emulsion with all the necessary additives, usually introduced during irrigation, is melted into two equal parts. The first part remains as a control, and in the second part, a 20% solution of ethylenediaminetetraacetic acid disodium salt is added in an amount of 10 ml per 1 kg of the emulsion. Both samples of the emulsion are then watered in a laboratory irrigation machine on a substrate on which small sawdust of iron is pre-applied. After this, the prepared film samples are developed in the X-ray developer for 8 minutes, and then fixed, washed and dried.
На фиг. 1 представлено по вление «точек, вызываемое частицами железа в контрольном опыте; на фиг. 2 показана пленка, в которой устранено по вление «точек посредством введени двунатриевой соли этилендиаминтетрауксусной кислоты.FIG. 1 shows the appearance of "points caused by iron particles in the control experiment; in fig. Figure 2 shows a film in which the appearance of "points" is eliminated by the introduction of ethylenediaminetetraacetic acid disodium salt.
