摘要： The invention relates to aqueous dyestuff formulations which contain at least one telomer of the formula I ##STR1## or a salt thereof, in addition to at least one anionic dispersant and optionally further ingredients. In formula I the symbols have the following meanings: X is hydrogen or ##STR2## Y is hydrogen, --SO.sub.4 H or ##STR3## each of R.sub.1 and R.sub.2 independently of the other is hydrogen, C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by a carboxyl group or is carboxyl; and the sum of n+m is an integer from 2 to 350. These compositions have good storage stability and redispersibility and are particularly suitable for use in the continuous dyeing process.

摘要： The invention relates to a process for the preparation of storage stable compositions of sparingly soluble or water-insoluble colorants, which process comprises mixing an aqueous suspension of at least one sparingly soluble or water-insoluble colorant with at least one surface-active substance, subjecting the mixture to ultrafiltration through an asymmetrical membrane which contains ionic groups and has a pore diameter of 1 to 500 .ANG. and a cut-off level in the molecular weight range from 300 to 500, subsequently subjecting the resultant concentrate to wet grinding and, if desired, drying, in particular spray drying the dispersion so obtained. The colorant compositions are particularly suitable for preparing padding liquors, dyebaths and printing pastes for coloring and printing textile materials, especially those made from cellulose and synthetic polyester.
摘要翻译：本发明涉及一种制备易溶或水不溶性着色剂储存稳定组合物的方法，该方法包括将至少一种微溶或不溶于水的着色剂的水性悬浮液与至少一种表面活性物质混合，该混合物通过包含离子基团并且具有1至500个ANGSTROM的孔径和在300至500的分子量范围内的截止水平的不对称膜超滤，随后将所得浓缩物湿法研磨，并且如果需要，干燥，特别是喷雾干燥如此获得的分散体。着色剂组合物特别适用于制备用于着色和印刷纺织材料的填充液，染浴和印刷浆料，特别是由纤维素和合成聚酯制成的那些。

摘要： Disclosed is a solid preparation containing at least one anionic dye or optical brightener, at least one anionic compound having hydrotropic activity, and/or at least one anion-active solubilising agent as well as optionally further additives, such as and preferably a anti-dust agent, whereby this preparation has a very good solubility especially in cold water compared with that of equally strong dyes diluted with customary fillers and can be used for producing aqueous dye preparations useful for dyeing and printing materials dyeable with anionic dyes or optical brighteners.
