These compounds are prepared by initially reacting epoxide with a phenol or naphthol and subsequently oxalkylating. The reaction products are used as dispersants for the preparation of aqueous pigment dispersions.

Abstract: Process for the dyeing of textile material of polyacrylonitrile which contains sulfonic acid groups, which comprises using as carriers compounds of the general formula R1 ¦R4 R2 - Ar - SO2 - N ANGLE ¦R5 R3 in which R1, R2 and R3 each represent a hydrogen, chlorine or bromine atom, an alkyl or alkoxy group of 1 to 4 carbon atoms or a nitro group, Ar represents a benzene or naphthalene ring, R4 represents a hydroxy-alkyl group of 1 to 4 carbon atoms, and R5 represents a hydrogen atom, an alkyl or hydroxy-alkyl group of 1 to 4 carbon atoms, a cyanoethyl group, an alkenyl group of 2 to 4 carbon atoms, a benzyl or cyclohexyl group. By using these compounds as carriers deep shades with an excellent levelness can be obtained and due to their high boiling point the danger of forming so-called carrier-spots on the goods is diminished.
