    摘要： Stable, concentrated, liquid preparations of 1: 2 metal complex azo or azomethine dyes are obtained by metallizing the metal-free azo or azomethine intermediates containing at most one sulfonic acid group in form of their moist, almost salt-free washed, filter cakes with aqueous slurries of complex forming, preferably cobalt or chromium salts. Without isolation of the thus obtained metal complex dyes the dye slurries are then in situ converted into the stable, concentrated dye preparations by adjusting them to a final dye concentration.
    The dye preparations are produced in a very economic manner by avoiding any isolation of the metal complex dyes after the metallization step and by considerably reducing the amounts of effluents.
    The dye preparations obtained are suitable for the preparation of dye-baths or printing pastes which may be used in particular for dyeing and printing textile materials made of natural or synthetic polyamide fibres, and further of leather and paper.

    摘要翻译： 通过将含有至多一个磺酸基的无金属偶氮或偶氮甲碱中间体以其潮湿，几乎无盐的洗涤的滤饼的形式进行金属化，得到1：2金属络合物偶氮或偶氮甲碱染料的稳定的浓缩液体制剂， 复合成型水性浆料，优选钴或铬盐。 如果不分离由此得到的金属络合物染料，则将染料浆料调整至最终的染料浓度，然后将染料浆料原位转化为稳定的浓缩染料制剂。 通过避免在金属化步骤之后金属络合物染料的任何分离和显着降低流出物的量，以非常经济的方式制备染料制剂。 所得染料制剂适用于制备染浴或印花浆料，特别适用于染色和印花由天然或合成聚酰胺纤维制成的纺织材料，还有皮革和纸张。
