摘要 |
<p>In various aspects, the present invention provides optical bodies configured and arranged to reflect at least a portion of light over at least one wavelength region, the bodies comprising a plurality of first optical layers (12) comprising a polyester having terephthalate comonomer units and ethylene glycol comonomer units and a plurality of second optical layers (14) disposed in a repeating sequence with the plurality of first optical layers. The first optical layers also comprise a polymor having a glass transition temperature of at least 130 DEG C. <??>In other aspects, the invention provides optical bodies comprising a plurality of first optical layers, each first optical layer being oriented; and a plurality of second optical layers disposed in a repeating sequence with the plurality of first optical layers, each second optical layer comprising a blend of polymethylmethacrylate and polyvinylidene fluoride. <??>Methods of making the above-described optical bodies, and articles employing such optical bodies are also provided. <IMAGE></p> |
