П р и м ё f)P.,01 мол этил-пара-толуол сульфоната-2-метил-5бета-нафтилтйазола , иодэтилата 2-метилмеркапто-бензтиазола и триэтиламина нагревалось до кипени с 7 мл абсолютного спирта в течение 20 мин. Выпавший при этом густой массой желтый кристаллический осадок промывалс спиртом и эфиром и нерекристаллизовывалс из спирта. Выход красител составил 43% от теоретического. Температура плавлени - 287° (с разложением). Найденное содержание иода 23,73% и формула C26H23N2S2J, соответствуют структурной формуле красител :3-этил-5(бета-нафтил)-тиазол-2 (З-этнлбензтиазол-2)-метилцианинподид . Максимум поглош,ени этого красител - прп длине волны 445 ммк.P. f. And m. F) P., 01 mol of ethyl p-toluene sulfonate-2-methyl-5beta-naphthylthiazole, 2-methylmercapto-benzthiazole iodoxylate and triethylamine were heated to a boil with 7 ml of absolute alcohol for 20 minutes. A thick mass of the yellow crystalline precipitate formed was washed with alcohol and ether and non-recrystallized from alcohol. The output of the dye was 43% of theoretical. Melting point - 287 ° (with decomposition). The iodine content found is 23.73% and the formula C26H23N2S2J corresponds to the structural formula of the dye: 3-ethyl-5 (beta-naphthyl) -thiazol-2 (3-ethnylbenzthiazol-2) -methylcyanine podid. The maximum is cool, this dye is a wavelength of 445 MMK.
Пример 2. В хлоросеребр ную эмульсию с естественной чувствительностьЕО So,2-0,01 (по ГОСТ 2817-50) введен метанольный раствор красител ;3-этил-5-пара-феноксифепилтиазол-2; З-этилбензтиазол-2 монометинцианин иоднда из расчета 4 10 мол на 1 кг эмульсии. При этом чувствительность эмульсии подн лась до So,2-0,1. При увеличении дозы сенсибилизатора до 8 и 12 мол чувствительность эмульсии подн лась соответственно до So,2-0,14 и 0,18. При этой чувствительности зона сенсибилизации простиралась до 520 ммк при максимуме 480 ммк.Example 2. A methanolic solution of the dye; 3-ethyl-5-para-phenoxy-epilithiazol-2; was introduced into the chloro-silver emulsion with natural sensitivity ЕО So, 2-0.01 (GOST 2817-50); Z-ethylbenzthiazol-2 monomethine cyanine iodnda at the rate of 4 10 mol per 1 kg of the emulsion. At the same time, the sensitivity of the emulsion rose to So, 2-0.1. With an increase in the dose of the sensitizer to 8 and 12 mol, the sensitivity of the emulsion rose to So, 2-0.14 and 0.18, respectively. With this sensitivity, the sensitization zone stretched to 520 hM at a maximum of 480 hM.
Предмет изобретени Subject invention
Способ сенсибилизации фотографических хлоросеребр ных эмульсий с помош;ью монометинцианиновых красителей, отл и ч а ю ш, и и с тем, что в качестве сенсибилизаторов примен ют монометинтиазолотиацианины , за мещенные в п том положении тиазольного кольца арильными заместител ми, обш,ей формулыThe method of sensitization of photographic chlorine-silver emulsions with the help of monomethine cyanine dyes, and with the fact that monomentine thiazole thiocyanines substituted in the fifth position of the thiazole ring with aryl substituents, general formula, are used as sensitizers.
