摘要： Chlorozincate salts of thiazolium azo compounds are prepared by reacting thiazolium azo compounds with an dialkylsulfate having from 1 to 4 carbon atoms in the alkyl radicals, which process comprises carrying out the reaction in an aqueous medium at a temperature of from about 10.degree. to 50.degree. C. in the presence of a zinc compound capable of binding acid, and with the use of from 1.8 to 2.5 mols of the dialkylsulfate, calculated on the starting azo dyestuff, at a pH not exceeding 8, preferably at 3-7. The prepared thiazolium azo compound is precipitated as chlorozincate salt, especially by means of an alkali metal chloride. According to this process, the chlorozincate salts are obtained in higher purity. A perceptible decomposition of the thiazolium azo compound does not occur. Chemicals, for example the alkylation agent and acid-binding agents need be used in a small quantity. In addition to this economy and to the less pollution of the waste water, the process has the advantage that it can be carried out with the use of a small reaction volume.

摘要： Improvement of a process for spin-dyeing acid-modified polymers or copolymers of acrylonitrile in which cationic quaternary dyestuffs are added to the spinning mass and spun according to the wet-spinning procedure. The improvement is characterized by using dyestuffs characterized by a migration factor M of 20 or less than 20, by a combination index K of less than 2.5 and a cation weight of more than 310. Migration factor M and combination index K are known values in the dyestuff field or can be determined. The dyestuff to be used according to the invention can belong to the most different classes of dyestuffs; they fix rapidly on the polymer, and thus they do not color, or color only to a minor extent, the coagulation, stretching and washing baths although they are soluble in water and aqueous solutions of these baths. The fibers and filaments obtained by the process of the invention have outstanding fastnesses to wet processing and, owing to the absence of dyestuff aggregates at the surface of the fiber such as occur when spin-dyeing with pigments, very good fastnesses to dry and wet rubbing. The fibers are intense, absolutely transparent and free from specks.
摘要翻译：改进将染色酸改性聚合物或丙烯腈的共聚物的方法改进，其中将阳离子季染料加入到纺丝织物中并根据湿纺丝方法纺丝。改进的特征在于使用迁移因子M为20或小于20的染料，组合指数K小于2.5，阳离子重量大于310.迁移因子M和组合指数K为染料领域或可以确定。根据本发明使用的染料可以属于最不同类型的染料; 它们快速固定在聚合物上，因此它们不会在凝固，拉伸和洗涤浴中颜色不浅或仅在较小程度上着色，尽管它们可溶于水和这些浴的水溶液。通过本发明的方法获得的纤维和细丝具有优异的湿法加工牢度，并且由于在用颜料旋转染色时在纤维表面没有染料聚集体，因此具有非常好的干湿摩擦牢度。纤维是强烈的，绝对透明的，没有斑点。

摘要： A process for the direct preparation of pure thiazolazo compounds had been found with the use of a 2-aminothiazole as diazo or azo component in a coupling process wherein the 2-aminothiazole used therein is subjected to the usual coupling reaction, if used as diazocomponent after diazotation, without intermediate isolation after its preparation in known manner. This process avoids the preparation of the 2-aminothiazoles as starting compounds in its solid form and the expensive purification of these instable compounds and yields now very pure azo products.
