Coatings are formed by applying to article a copolymer of a water soluble base polymer having graft polymerized thereto an organic moiety that includes a group that reacts with water to form a silanol group, and then curing the copolymer to form a crosslinked hydrogel coating that is absorbent, lubricious and substantially non-water soluble. Coating compositions, coated articles the subject coatings are also described.
L'invention porte sur des revêtements obtenus par application sur un article d'un copolymère fait d'un polymère de base hydrosolubles sur lequel est greffé par polymérisation-greffage un fragment organique réagissant avec l'eau pour former un groupe silanol, ledit copolymère étant ensuite durci pour donner un hydrogel absorbant, lubrifiant et sensiblement non hydrosoluble. L'invention porte également sur des compositions de revêtements, et des articles en étant revêtus.
