hydrophilic monomers each bearing one or more alkene and/or alkyne groups;
component B comprises one or more hydrophilic polymers each bearing two or more alkene and/or alkyne groups;
component C, if present, comprises one or more beneficial agents each bearing one or more alkene or alkyne groups; and
component D, if present, comprises one or more low molecular weight cross-linking agents each bearing two or more functional groups independently selected from thiol, alkene and alkyne groups;
wherein the cross-linked copolymer is formed by radical polymerisation involving the alkene and/or alkyne groups of components A, B and C (if present) and involving the functional groups of component D (if present);
wherein the hydrophilic coating optionally comprises component E which comprises one or more beneficial agents, wherein component E does not form a copolymer with components A, B, C (if present) and D (if present);
and wherein the hydrophilic coating is covalently attached to the surface of the substrate.
