| abstract |
The invention relates to surfactants of the general formula A - [(XO) n -YZ] m in which A represents a residue of an unmodified or modified natural resin or its esterification product with a polyhydric alcohol, X is 1,2-ethylene or propylene, Y is defined as X or is -CH₂CHOHCH₂-, Z is OH or (Ia) (-NH-Q) a -NR- (Q-NH-) b H (Ia) in the RH or C₁-C₂₄-alkyl or (-CH₂CH₂O) p -H, where p is 1-100, or (-Q-NH) c -H, Q C₁-C₂₄-alkylene, which can be interrupted by oxygen atoms, a 0-5 and c 0-5 mean where at least one Z is different from OH, n for 0 to 150 and m represents 1 to 5.n n n The compounds are obtained by oxalkylating resins or their esterification products with polyhydric alcohols and, after conversion of hydroxyl groups into suitable leaving groups, with amines of the formula Z-H. The products are particularly suitable as coupling aids, dispersants and preparation agents for colorants. |
