Abstract
In embodiments, a retroreflective article with a flat surface and an infrared (IR) reflective boundary exhibits high transmittance of infrared radiation from the reflective boundary through the flat surface and exhibits low transmittance of infrared radiation from the flat surface through the reflective boundary. In embodiments, the asymmetric infrared reflective article is abbreviated as AIR(λ) article, meaning that the asymmetric transmittance is defined over a wavelength range defined as λ.
