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.
