| abstract |
The present invention particularly relates to a substrate having a surface with a hydrophilic coating comprising a crosslinked copolymer of components A and B and optional components C and D, wherein component A comprises at least one alkene and / Wherein component B comprises at least one hydrophilic polymer having at least two alkenyl groups and / or alkyne groups, and component C, if present, comprises one or more C 2 -C 16 hydrophilic monomers, (S), each having at least one alkenyl group or alkynyl group, wherein component D, if present, is selected from the group consisting of one species having two or more functional groups independently selected from thiol groups, alkenyl groups and alkyl groups, (S), wherein the cross-linked copolymer comprises a functional group of component D (if present) comprising an alkene and / or alkyne group of components A, B and C Wherein the hydrophilic coating optionally comprises a component E comprising at least one beneficial agent, wherein component E comprises at least one of components A, B, C (if present) and D (if present) Wherein the hydrophilic coating is not covalently bonded to the surface of the substrate. |
