<P>PROBLEM TO BE SOLVED: To provide a multilayer light-reflecting optical body, particularly, a multilayer optical body that reflects light over a given range of wavelengths (for example, a mirror, a color mirrored film, an IR reflective film and a UV reflective film). <P>SOLUTION: The optical body comprises: a plurality of first optical layers, with each optical layer being oriented and comprising a polyester having a terephthalate comonomer unit and an ethylene glycol comonomer unit; and a plurality of second optical layers disposed in a repeating sequence with the plurality of first optical layers, with each optical layer comprising a copolymer of polymethyl methacrylate, the copolymer containing a comonomer unit that decreases a glass transition temperature of the copolymer below a glass transition temperature of the polyester of the first optical layers. The optical body is configured and arranged to reflect at least a part of light over at least one wavelength region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
