Abstract:
1. A polymer comprising at least one residue of a molecule comprising a molecular structure depicted by Formula I: wherein A is an optionally substituted aryl radical and Z is the residue of a moiety selected from 2-pyrazolin-5-ones, dimedone (5,5-dimethyl-1,3-cyclohexanedione), acetoacetamides, malonamides, barbituric acid and 1,3-propanediones; with the provision that when Z is 2-pyrazolin-5-one, A is selected from wherein B is selected from —CON(R L is selected from C L m is selected from 0, 1 and 2; n is 1, 2, or 3; R is hydrogen or one to three groups selected from C R R R R R R Q is an ethylenically-unsaturated polymerizable group selected from; wherein: R R R R R wherein the molecule comprises at least one ethylenically-unsaturated polymerizable group (Q), wherein when Z does not comprise at least one Q group, then m is 1 or 2.
