Abstract

Watersoluble oxalkylated novolaks of the formula ##STR1## wherein R.sup.1 is alkyl of 1 to 18 carbon atoms, R.sup.2 is hydrogen or R.sup.1, X is ethylene or propylene, m is 6 to 100 and n is 1 to 12, are preparation agents for disperse dyestuffs. Disperse dystuff preparations containing these compounds have a stable and uniform distribution of the dyestuff particles, even with high dyestuff concentrations, and show good dyeing properties, low or no foam in dyebaths and useful viscosities in printing pastes.
