Abstract: The aromatic formaldehyde condensation products, which are substantially colorless and water-soluble and contain sulphonate and/or carboxylate groups, are obtainable by adding agents which have a reducing action during and/or after the condensation reaction, and are suitable for the treatment of textiles and leather.

Abstract: Sulphosuccinamide acids and their salts corresponding to the following general formula ##STR1## wherein X denotes the residue of a hydrophobic, optionally branched vinyloligomer having an average molecular weight M.sub.n of from 200-5,000, preferably from 300-3,000,of the groups denoted byR.sup.1 R.sup.2, one is hydrogen and the other is --SO.sub.3 M, andn represents a number with a value of from 1.4-3.0, preferably form 1.6-2.3. andM denotes hydrogen, an alkali metal, or an ammonium, C.sub.1 -C.sub.4 -alkyl-ammonium or C.sub.2 -C.sub.3 -hydroxy alkyl-ammonium group.

Abstract: The invention relates to 2-phosphonobutane-1,2,4-tricarboxylic acid derivatives, which can be obtained by reaction of the tricarboxylic acid with C.sub.6-20 -alcohols and which are suitable as auxiliaries (emulsifiers) for emulsion polymerization.

Abstract: Condensation products of alkylenediamines of the formulaH.sub.2 N--C.sub.n H.sub.2n --NH.sub.2 I,in whichn represents 4-10,and an epihalogenohydrin or 1,3-dihalogeno-2-hydroxypropane are used for the after-treatment of natural and synthentic fibre materials which are dyed with anionic dyestuffs and contain polyamide groups.

Abstract: The treatment of cellulosic fibre materials before or after dyeing or printing with direct or reactive dyestuffs is carried out with aqueous liquors which contain quaternized polyethers which are obtained by condensation of N-2-hydroxyalkylamines of the formula ##STR1## in which R.sub.1 and R.sub.2, independently of each other, denote hydrogen or a C.sub.1 -C.sub.4 -alkyl radical andR denotes a C.sub.1 -C.sub.18 -alkyl, cycloalkyl, aralkyl or aryl radical or one of the hydroxyalkyl groups ##STR2## with the proviso that the amount of N-2-hydroxyalkylamines in which R stands for a hydroxyalkyl group accounts for no more than 20 percent by weight of the hydroxyalkylamines used,if desired by co-condensation with polyols of the formulaA(OH).sub.n IIin whichA denotes a 2-, 3- or 4-valent aliphatic, cycloaliphatic, araliphatic or aromatic radical andn is a number from 2 to 4,and subsequent quaternization.
