Claim Text:
1. A multi-layer optical film comprising a plurality of at least first and second polymeric optical layers having a major surface and collectively reflecting at least 50 percent of incident UV light over at least a 30 nanometer wavelength range in a wavelength range from at least 300 nanometers to 400 nanometers, and a third optical layer having first and second generally opposed first and second major surfaces and absorbing at least 50 percent of incident UV light over at least a 30 nanometer wavelength range in a wavelength range from at least 300 nanometers to 400 nanometers, wherein the major surface of the plurality of first and second polymeric optical layers is proximate to the first major surface of the third polymeric optical layer, wherein there is not another multi-layer optical film proximate the second surface of the third optical layer, and wherein at least one of the first or second polymeric optical layers comprise a UV absorber.
