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 polymer composition comprisingi) a first component polymer comprising a plurality of polymerized monomer units derived from an ethylenically unsaturated monomer having pendent hydrophilic groups, and a plurality of polymerized monomer units derived from an ethylenically unsaturated monomer having pendent Michael donor groups; and

    ii) a crosslinking agent comprising at least two Michael acceptor groups, andiii) optionally a monoacryl component; and

    b) crosslinking said first component polymer and crosslinking agent, in the presence of a basic catalyst.
