Claim:
1. A method of preparing a ligand functional substrate comprising the steps of: a) providing a substrate, b) free-radically grafting the substrate in the presence of a Type II photoinitiator of the general formula: in which Ar is a substituted or unsubstituted aryl group having 6 to 12 carbon atoms optionally substituted with a C 1 to C 12 alkyl group, a C 1 to C 12 alkoxy group, or a phenyl group; and R 13 is a C 1 to C 6 alkyl group, a cycloalkyl group having 3 to 14 carbon atoms, or Ar; with a guanidinyl-functional (meth)acryloyl monomer of the formula: wherein R R each R R R X o is 0 or 1, and n is 1 or 2; and wherein the substrate is provided with a primer layer disposed on the substrate comprising the reaction product of: 1) a polyamine polymer; and 2) a polyfunctional crosslinking agent for the polyamine polymer.
