Beschreibung
Zusammenfassung:	The invention relates to an article having a polyurethane surface which has been rendered hydrophilic as well as to a method of rendering a polyurethane surface hydrophylic. According to the invention there is provided an article having a poyurethane surface provided with a coating of hydrophilic polyacrilamide or polymethacrylamide (other than poly(N-(mono hydroxy)propyl methacrylamide) bonded to the polyurethane by residues of a compound having a first functional group reactive with the polyurethane and a second functional group reactive with the polyacrylamide or polymethacrylamide. Elément présentant une surface en polyuréthane qui a été rendue hydrophile et méthode consistant à rendre hydrophile ladite surface en polyuréthane. L'invention porte sur un élément présentant une surface en polyuréthane enduite d'un revêtement de polyacrylamide ou de polyméthacrylamide hydrophile (autre que que le poly(N-(mono hydroxy)propyl méthacrylamdide) lié au polyuréthane par le résidu d'un composé renfermant un premier groupe fonctionnel qui réagit avec le polyuréthane et un deuxième groupe fonctionnel qui réagit avec le polyacrylamide ou le polyméthacrylamide.
