1. A cured hardcoat composition comprising:

  • (a) a brominated polymer comprising monomeric units derived from a polymerizable composition comprising (i) an aromatic brominated (meth)acrylate compound of formula (I) wherein;

    R is hydrogen or methyl;

    R1 is a straight or branched alkyl;

    L is a straight or branched alkylene;

    x is an integer from 1 to 4; and

    m is an integer from zero to 1; and

    (b) substantially non-agglomerated, inorganic oxide particles that are less than about 50 nanometers in size, selected from the group consisting of silica, titania, alumina, zirconia, and mixtures thereof;

    wherein the cured hardcoat composition has an index of refraction of at least about 1.5, and a pencil hardness of greater than or equal to 1H.
