Description
Недостатком современных инфрахроматических материалов вл егс сравнительно невысока исходна светочувствительность и плоха сохран емость фотосвойств, т. е. быстрое снижение светочувствительности и рост вуали при продолжительном хранении.The disadvantage of modern infrachromatic materials is the relatively low initial sensitivity and poor preservation of photo properties, i.e., a rapid decrease in sensitivity and growth of the veil during prolonged storage.
До насто щего времени не были известны вещества, введение которых в эмульсию позволило бы предотвратить исходную светочувствительность от падени или замедлить это падение.Until now, no substances were known which, if introduced into the emulsion, would prevent the initial photosensitivity from falling or slow down this decrease.
Способ согласно изобретению дает возмо - ность устранить указанный недостаток путем введени стабилизатора в эмульсию, сенсибилизированную трикарбоцианиновыми красител ми.The method according to the invention makes it possible to eliminate this drawback by introducing a stabilizer into an emulsion sensitized with tricarbocyanine dyes.
Отличительна особенность предлагаемого способа состоит в том, что в эмульсию перед поливом ввод т, кроме обычных добавок, трифенилфосфин в количестве 0,5 ,5 10 гм на литр эмульсии.A distinctive feature of the proposed method is that, in addition to the usual additives, triphenylphosphine in the amount of 0.5, 5 10 gm per liter of emulsion is introduced into the emulsion before the irrigation.
Пример 1. В высокочувствительную аммиачную эмульсию с 3%-ным молекул рным Agj, значение рВг которой с помощью промывки водой доведено до 3,8, ввод т следующие добавки (на 1 Example 1. The following additives were added to a highly sensitive ammonia emulsion with 3% molecular Agj, the pBr value of which was raised to 3.8 with water washing.
трифенилфосфин 0,66 10 гм/ке, раствор в ацетоне - 20 мл; стабилизатор 5-метил-7-окси-1,3,4-триазоиндолицин 2 гм/л, раствор - 30 мл; сенсибилизатор 2,2-диэтилтиотрикарбоцианиниодвд 4- 10 ем/л, спиртовой раствор - 16 мл.Triphenylphosphine 0.66 10 gm / ke, solution in acetone - 20 ml; stabilizer 5-methyl-7-hydroxy-1,3,4-triazoindolitsin 2 gm / l, solution - 30 ml; a 2,2-diethylthiotricarbocyanine iodine sensitizer with 4-10 cm / l, an alcohol solution - 16 ml.
Эмульси после введени всех добавок выдерживаетс необходимое врем , наноситс на подложку на поливной машине и сущитс . Готова пленка подвергаетс сенситометрическому испытанию.After the introduction of all the additives, the emulsion is kept for the necessary time, applied to the substrate on an irrigation machine and dried. The finished film is subjected to a sensitometric test.
Пример 2. Эмульси та же, то и в примере 1, но примен етс сенсибилизатор 3- (|3-оксиэтил) -3-метилтиотназолинатрикарбоцианиниодид (35 мл концентрации I:15000).Example 2. The emulsion is the same as in Example 1, but a 3- (| 3-hydroxyethyl) -3-methylthiothynazolinate tricarbocyanine iodide sensitizer is used (35 ml concentration I: 15000).
