1. A process for making a substrate bearing a coating of a crosslinked polymer composition on at least one surface thereof, comprising the steps of:

  • (a) coating onto said substrate a crosslinkable oligomer composition comprising;

    (1) a first component oligomer comprising a plurality of polymerized monomer units having pendent, free-radically polymerizable functional groups, and a plurality of polymerized monomer units having pendent, hydrophilic poly(alkylene oxide) groups; and

    (2) a second component oligomer comprising a plurality of polymerized monomer units having pendent, photoinitiator groups; and

    (b) photochemically crosslinking said first component oligomer and second component oligomer, in the presence of a photoinitiator, by forming covalent bonds between said pendent, free-radically polymerizable functional groups of said first component oligomer said second component oligomer.
