Abstract

The present invention is drawn to an aqueous polyurethane dispersion comprising: —anionic polyurethane particles comprising both free pending carboxylate groups of formula —COOMwhere Mis a cation resulting from neutralization of carboxylic acid groups with a base, and pending carboxylate ester groups resulting from esterification of free carboxylic acid groups with an epoxysilane, —crosslinking particles made of water-insoluble transition metal compounds. It is also drawn to a method of coating a substrate comprising applying such an aqueous polyurethane dispersion onto a substrate and letting it dry, preferably without applying any heat or radiation.
