When the laminate is contacted with radiation having p-polarized radiation at an angle of 60° relative to normal of the laminate, the laminate exhibits a LTA of at least 70% and a reflectivity of the p-polarized radiation of at least 10%. A display system and method of projecting an image in a heads-up display is also disclosed.
