Abstract
In various embodiments, the present disclosure provides for reflective materials, articles and methods incorporating a mesh arrangement of multiple, discrete retroreflective canted cube corner reflectors each having generally flat incident surfaces and high transparency, with a geometry and a refractive index ratio sufficiently high enough to produce a high degree of total internal reflection (TIR) that results in anisotropic retroreflectivity.
