Beschreibung
Zusammenfassung:	A composition [composition (C)] which comprises: - at least one (per)fluoropolyether phosphate polymer [PFPE-phosphate (P1)]; - at least one polysaccharide [polymer (P2)]; and - at least one hydroxy-carboxylic acid comprising at least one carboxylic acid group and at least one hydroxyl group [hydroxy-carboxylic acid (A)] is herein disclosed. Disclosed is also a method for imparting grease and oil repellence to a substrate which comprises applying the composition (C) to said substrate and a substrate (S) treated with composition (C). La présente invention concerne une composition [composition (C)] comprenant : - au moins un polymère de phosphate de (per)fluoropolyéther [PFPE-phosphate (P1)] ; - au moins un polysaccharide [polymère (P2)] ; et - au moins un acide hydroxy-carboxylique comprenant au moins un groupe acide carboxylique et au moins un groupe hydroxyle [acide hydroxy-carboxylique (A)]. L'invention concerne également un procédé permettant de conférer un caractère répulsif envers les graisses et les huiles à un substrat, qui consiste à appliquer la composition (C) audit substrat et un substrat (S) traité avec la composition (C).
