Abstract
A multilayer polymer film has an optical stack including a plurality of alternating polymer layers with skin layers having mechanical, optical, or chemical properties differing from those of the layers in the optical stack, wherein the refractive indices in the in-plane direction nx and ny, and the refractive index in the thickness direction nz for each layer are all selected to obtain optical effects such as reflection, transmission, and/or polarization.
