Description
Способы получени гиперсенсибилизированных фотографических эмульсий известны, но основным недостатком их вл етс крайне плоха стабильность, характеризуема интенсивным ростом вуали. Также известен способ получени 5-метил-7-окси-1, 3, 4-триазоиндолизина.Methods for producing hypersensitized photographic emulsions are known, but their main drawback is extremely poor stability, characterized by intensive growth of the veil. A method for producing 5-methyl-7-hydroxy-1, 3, 4-triazoindolizine is also known.
Гиперсенсибилизированные фотографические эмульсии, полученные по предлагаемому способу, этих недостатков не имеют. Так при получении их примен ютс стабилизаторы, в качестве которых примен ют 5-метил-7-окси-1, 3, 4-триазоиндолизин.Hypersensitized photographic emulsions obtained by the proposed method do not have these disadvantages. Thus, in preparing them, stabilizers are used, in which 5-methyl-7-hydroxy-1, 3, 4-triazoindolizin is used.
Предлагаемый способ состоит в том, что после обычной гиперсенсибилизирующей ванны любого состава фотографические материалы обрабатываютс в ванне, содержащей от . . 1 . 10 2% водного раствора 5-метил-7-окси-1, 2, 3-триазоиндолизина. После такой обработки врем использовани фотоматериалов повышаетс до 1-2 мес цев.The proposed method consists in that after a conventional hypersensitizing bath of any composition, photographic materials are processed in a bath containing from. . one . 10 2% aqueous solution of 5-methyl-7-hydroxy-1, 2, 3-triazoindolizina. After this treatment, the use time of photographic materials rises to 1-2 months.
