Articles such as catheters or balloons that have an ester-linked poly(ester- block-amide) substrate have a lubricious hydrogel coating which suppresses particle development under accelerated aging conditions. A polymerizable coating composition is applied to the substrate without application of an intervening primer layer and cured. The coating composition comprises an uncrosslinked polyvinylpyrrolidone polymer that is free of attached photoinitiator groups and at least one polyfunctional ethylenically unsaturated monomer.
L'invention concerne des objets tels que des cathéters ou des ballonnets qui possèdent un substrat de poly (ester-bloc-amide) à liaison ester. Ces objets portent un revêtement de type hydrogel à caractère lubrifiant, qui réduit le développement de particule dans des conditions de vieillissement accéléré. Une composition de revêtement polymérisable est appliquée sur le substrat, sans application d'une couche de primaire intercalaire, et durcie. La composition de revêtement comporte un polymère polyvinylpyrrolidone non réticulé qui est exempt de groupes photo-initiateurs attachés, et au moins un monomère polyfonctionnel insaturé éthylénique.
