Abstract: 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 componentsa) at least one compound of the formula (I)where A is NR 3-q or OR 2-p; p,q means q when A is NR 3-q, and p when A is OR 2-p; R , R , R are each hydrogen or C1-C6-alkyl; R 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 R , R , R is C1-C6-alkyl when A is OR 2-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)where A, R , R , R , R , 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.

Abstract: Sulfonated and oxidized indene polymers obtainable by (a) polymerization of indene or indene derivatives of the general formula I I where R1 is hydrogen, methyl or ethyl and n is 1 or 2, or of mixtures which contain the compounds I as well as other copolymerizable and/or non-polymerizable organic compounds in an amount of at least 10% by weight, (b) sulfonation of the polymer with a sulfonating agent at from 40 to 130.degree.C, and (c) non-chain-degrading oxidation of the polymer at from 80 to 180.degree.C. These indene polymers are suitable for use as dispersants for example in dye and pigment preparations.
