The dyeing or printing of fibrous materials is improved by using a compound of the formula R1-CHX-(CH2-CH2-O)n-R2 in which R1 is alkyl of four to 20 carbon atoms, X is chlorine or bromine, n is a number of three to about 200 and R2 is an aliphatic hydrocarbon radical of up to 20 carbon atoms, alkylphenyl with up to 12 carbon atoms in the alkyl moiety, phenyl, naphthyl, benzyl, the acyl residue of a fatty acid of up to 18 carbon atoms, benzoyl or the group of the formula R1-CHXCH2-CH2, as dispersing, levelling or after treating agent. The improvement consists in the combination of dispersing and levelling properties. |
