Patent ID: 7282272

Claim:
A brightness enhancing film having a polymerized structure comprising the reaction product of a) at least about 15 wt-% of one or more first monomers selected from the group consisting of: i) a monomer comprising a major portion having the structure wherein R1 is independently hydrogen or methyl, R2 is independently hydrogen or bromine, Q is independently O or S, and Z is independently —C(CH 3 ) 2 —, —CH 2 —, —C(O)—, —S—, —S(O)—, or —S(O) 2 —; ii) a monomer comprising a major portion having the structure wherein R1 is independently hydrogen or methyl, R2 is independently hydrogen or bromine, Q is independently O or S, Z is independently —C(CH 3 ) 2 —, —CH 2 —, —C(O)—, —S—, —S(O)—, or S(O) 2 , and L is a linking group independently selected from linear or branched C 2 -C 12 alkyl groups wherein the carbon chain is optionally substituted with one or more oxygen groups, one or more hydroxyl groups, or a combination thereof; and mixtures of i and ii; b) at least about 10 wt-% of inorganic nanoparticles; c) optionally a crossliniking agent.
