Beschreibung
Zusammenfassung:	The present invention relates to a composition for coating a support comprising: -an aqueous solvent; -a polycarboxylic acid; -a catalyst for the formation of an anhydrous acid intermediate starting from polycarboxylic acid; -a sol-gel precursor, all the groups of which are hydrolysable, with functional particles and/or a sol-gel precursor comprising at least one non-hydrolysable functional group; or a sol-gel precursor comprising at least one non-hydrolysable functional group, and optionally functional particles, the use thereof for coating a support and the coating thus obtained. La présente invention concerne une composition pour le revêtement d'un support comprenant : -un solvant aqueux; -un acide polycarboxylique; -un catalyseur de la formation d'un intermédiaire anhydre d'acide à partir de l'acide polycarboxylique; -un précurseur sol-gel,dont tous les groupements sont hydrolysables,avec des particules fonctionnelles et/ou un précurseur sol-gel comprenant au moins un groupement fonctionnel non hydrolysable; ouun précurseur sol-gel comprenant au moins un groupement fonctionnel non hydrolysable,et éventuellement des particules fonctionnelles, son utilisation pour revêtir un support et le revêtement ainsi obtenu.
