Multilayer optical bodies
First Claim
1. An article, comprising:
- a mirror comprising a plurality of first optical layers, each first optical layer being oriented and comprising a polyester having terephthalate comonomer units and ethylene glycol comonomer units, 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 polymeric material selected from a polyolefin copolymer and an acid-modified polyolefin, the mirror being configured and arranged to reflect at least a portion of light over at least one wavelength region.

Abstract
Optical bodies, comprising: a plurality of first optical layers comprising a first polymer composition that comprises (i) a polyester portion having terephthalate comonomer units and ethylene glycol comonomer units, and (ii) a second portion corresponding to a polymer having a glass transition temperature of at least about 130° C.; and a plurality of second optical layers disposed in a repeating sequence with the plurality of first optical layers. Also disclosed are optical bodies comprising: (a) a plurality of first optical layers, each first optical layer being oriented; and (b) a plurality of second optical layers, disposed in a repeating sequence with the plurality of first optical layers, 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.
