A composition comprising:
- a first component comprising at least one vinyl phospholipid;
- a second component of formula:
- wherein R2, R3 and R4 are independently or all H or halogen;
- and
- R1 is a moiety selected from the group consisting of H, halogen, formyl, carboxyl, cyano, ester, amide, alkyl, alkoxy, oxoalkyl, alkenyl, alkynyl, aryl or arylalkyl,
- wherein at least one of R1, R2, R3 and R4 are substituted with a moiety selected from the group consisting of vinyl moieties and acrylate moieties;
- and
- a third component comprising a hydroxamate of the formula
- wherein R10 is selected from the group consisting of vinyl groups, hydroxy alkyl acrylate groups, hydroxy alkyl methacrylate groups, alkyl amines, acrylamides, methacrylamides, alkyl groups, alkoxy groups, alkenyl groups, polymers terminated with the foregoing groups, and combinations thereof, and R11 comprises hydrogen.
