| 摘要 |
The present invention provides a fluorochemical composition comprising one or more condensates of (i) a methylolated amine or an alkoxylated derivative thereof, (ii) a hydrocarbon compound selected from an alcohol, a thiol, an amide or an acid having hydrocarbon group of at least 6 carbon atoms and which hydrocarbon group is optionally substituted with up to 3 substituents and (iii) a fluorinated compound corresponding to formula (I), wherein: R f represents a fluorinated aliphatic group; X 1 represents an organic divalent linking group; Z 1 represents hydroxy, thiol, an amide group or an acid group and n is 0 or 1. The present invention further provides the use thereof to impart water and oil repellency to a substrate, in particular to textile or leather. The present invention further provides a method of treatment of the substrate with the fluorochemical composition and a treated substrate. The fluorochemical compositions of the invention are readily soluble in non-fluorinated solvents and yield good oil and water repellency in particular on leather substrates. |
