摘要： A process for reduction clearing dyed or printed polyester textiles, which comprises adding, to an acidic dyeing liquor or a wash bath, an aftertreatment composition comprising as components a) at least one compound of the formula (I) Am[(CR1R2)mSO2M]p,q (I) where A is NR33−q or OR42−p; p,q means q when A is NR33−q, and p when A is OR42−p; R1, R2, R4 are each hydrogen or C1-C6-alkyl; R3 represents identical or different radicals selected from the group consisting of hydrogen, C1-C20-alkyl, C3-C8-cycloalkyl opt. substituted by from one to three C1-C4-alkyl radicals; M is the equivalent of an ammonium, alkali metal or a kaline earth metal ion; m is 0 or 1; p is 1 or 2; and q is 1, 2 or 3, subject to the provisos that at least one of R1, R2, R4 is C1-C6-alkyl when A is OR42−p and that, if m is 0: the compound of formula (I) is S2O4M2, and the compound of the formula (I) is used together with sufficient acid acceptor to raise the pH of the dyeing liquor or of the wash bath by from 1 to 3 units, b) optionally at least one compound of the formula (II) A[CR1R2)SO3M]p,q (II) where A, R1, R2, R3, R4, M, p,q p and q are each as defined for the formula (I), although the specific choice of these variables does not have to be the same for the compounds of the formulae (I) and (II) c) and optionally further additives.

摘要： Concentrated leuco indigo solutions useful for dyeing cellulosic textile material consist essentially of from 25 to 55% by weight of leuco indigo in the form of the leuco indigo salt, an amount which is essentially stoichiometrically sufficient to convert the leuco indigo into the neutral leuco indigo salt of a mixture of at least two alkali metal hydroxides wherein none of the alkali metal hydroxides accounts for more than 70 mol %, and water.
摘要翻译：用于染色纤维素纺织材料的浓缩的无色靛蓝溶液基本上由25至55重量％的无色靛蓝盐形式的无色靛蓝组成，其量基本上在化学计量上足以将无色靛蓝转化为中性无色靛蓝盐的至少两种碱金属氢氧化物的混合物，其中碱金属氢氧化物中的任何一种都不超过70mol％，和水。
