Description

Современные фотоматериалы требуют точиого Ш толщине нанесени эмульсиоиного сло , что оеобенно важно при по иве цветных пленок во избежание нарушени цветового баланса. Однако возможны случаи увеличени или уменьшени в зкости эмульсий (пониженна темнерат1,ра ;полива, повышенна температура студенени ), что приводит к неравномерности наносимого при ноливе светочувствительного сдо .Modern photographic materials require a precise thickness of the emulsion layer, which is especially important when applying color films in order to avoid disturbing the color balance. However, there are cases of increasing or decreasing the viscosity of the emulsions (low temper1, pa; watering, elevated temperature of frost), which leads to unevenness of the photosensitive material applied to the filament.

С целью регулировани в зкости эмульсий -в них согласно предлагаемому способу ввод т некоторые орга-нические 1В€ш;ества , в зыва1опоге активные трдапы же атины . При этом в случа х, когда требуетс понизить в зкость эмульсии, например , лри НИЗКИХ температурах полива , ввод т однюфувкпиональные вещества , например, мочевипу или а-петамид, а в -случае иеобходимостп повышени в зкости , наприме:р, при повышенных температурах полива, - бифункпиональНн;ве1Ц н гва . например, тликоколл.In order to regulate the viscosity of the emulsions - in them, according to the proposed method, some organic 1B € are introduced; in particular, active trinades of the same type are requested. In this case, in cases when it is necessary to lower the viscosity of the emulsion, for example, at low watering temperatures, one should be injected into the urine or a-petamide, and in the case of the necessary increase in viscosity, for example, at elevated watering temperatures , - bifunctional; for example, tlikokoll.

Добавки ввод т в фотографически 9му,иьсии перед поливом в колипр,«1тве 3%. .Additives are introduced in photographic 9th, before irrigation in the colipra, “Only 3%. .

Claims

1. A method of preparing photographic products for irrigation, of which it is necessary so that, in order to regulate the emulsion, used at low irrigation temperatures and elevated temperatures of the students, the emulsion is added to the emulsion. Rga and the substance that binds the active groups of gelatins.

2. A method according to claim 1, characterized in that, in order to fit the viscosity :-) a mixture, the ratio of the binder (the main binding substances, 1% hydrogen, acetamide or urea) is added to the latter.

3. Method p. 1, Distinguishing i; By the fact that, in order to increase the viscosity of the emulsion, bifush rational substances, for example, glimt ll, are added to it.
