Description

physical and mechanical indicators of photos are given. Example 9. The photo layer is developed and fi fixed as in Example 5 and treated in an oak solution of composition, g: sodium hydroxide-ethyethyladeatomatoaluminate 75; sodium pyrosulfite 10; water up to 1000 ml for 5 min at 20 ° C and the physicomechanical parameters of photollo are determined. Example 10. The photo layer is developed and fixed analogously to example 5 and treated in an oak solution of the composition: mucochloric acid 10 g, water up to 1000 ml for 5 minutes at 20 ° C and the physicomechanical indicators of photos are determined. Example 11. The photo layer is developed and fixed analogously to example 5 and treated in oak with a solution of the following composition: glutaric dialdehyde bisulfite derivative of 10 g, water up to 1000 ml, for 5 minutes at 20 ° C and the physicomechanical indicators of photollo are determined. The test results for examples 3-11 are given in table. 1 The physicomechanical parameters are determined as follows. Melting point A processed sample of a photographic material with a pencil of 5x5 mm in size applied to its emulsion layer is placed in a glass with an alkaline sulfite solution (caustic soda — 1.1 g, anhydrous sodium sulfite 50 g, water up to 1000 ml) at 20 C. Then the solution with the sample is heated at a rate of 1 ° C / min. The temperature of the solution, at which the deformation of the mesh occurs on the surface of the emulsion layer, is considered the temperature of the deformation, and the temperature at which flows of the molten emulsion appear on the surface of the emulsion layer, is considered the melting point of the EMULSION layer. The strength of the swollen photo. The processed sample of the photographic material is poured with distilled water at a temperature of 20 ° C, and a figured rod is lowered onto its surface, at the lower end of which there is a freely rotating metal sheet. An increasing load is applied to the rotating rod until it starts to push the emulsion layer of the photographic material. The load at which the layer is being forced is considered the strength of the swelling photo. Moisture content A sample of photo material of 5x10 cm in size is preliminarily kept in a desiccator for a day at a relative humidity of 60%, weighed with an accuracy of 0.0001 g. Then the sample is processed in photographic solutions, after which droplet moisture is removed from its surface and the sample is repacked. The water capacity (g / m) is determined by the formula: W (a -,, where a is the weight of the swelled sample; b is the weight of the dry sample. From the data in Table 1, it can be seen that the photo layer of amnammonium ethylene diamine tetraacetate ammonium metallate is most effectively structured. All tested tannins have virtually no effect on photographic characteristics of photographic materials when they are applied at the stages of chemical-photographic processing after development.The concentration of hydrogen films has a significant effect on the efficiency of tanning photographic materials. ion (pH) in a tanning solution. Table 2 presents data on the effect of the pH value of tanning solutions on the physicomechanical characteristics of black-and-white negative photographic material.From the data given in Table 2, it follows that at pH of tanning solutions in at an interval of 5.07, 0 that is optimal for the processing steps following the development, the most effective are ammonium ethylenediamine ammonium ammonium tetraacetatemetallate.
