Beschreibung
Zusammenfassung:	The invention concerns a method and a device for depositing at least one thin film of a liquid agent on a wireframe element such as an optical fiber designed to form a very fine coating on said wireframe element consisting in spraying the liquid agent on the wireframe element with spraying means, the wireframe element and the spraying means being in relative movement with respect to each other. Preferably, the liquid agent used is obtained from novel acrylphosphorus or metacrylphosphorus compounds. The method is most particularly adapted for coating optical fibers and enables to substantially improve the stress corrosion factor "n" of the fibers and to maintain said factor "n" after aging.
