Use of oxyalkylated novolaks as preparation agents for disperse dyestuffs and preparations made with said agents |
摘要 |
Watersoluble oxalkylated novolaks of the formula <IMAGE> (I) wherein R1 is alkyl of 1 to 18 carbon atoms, R2 is hydrogen or R1, 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.
