Claim:
1. An anisotropic magnetic flake, for forming a reflective coating, comprising a two-dimensional layered structure having a thickness in a range of 50 nm to 10 microns and a longest planar dimension in a range of 1 micron to 500 microns, the two-dimensional layered structure comprising: a continuous magnetic layer, absent of a grating, for aligning the anisotropic magnetic flake substantially parallel to a surface of the reflective coating when the anisotropic magnetic flake is disposed in a liquid carrier and under influence of an external magnetic field, a first reflector layer disposed on the first surface and a second reflector layer disposed on the second surface, such that the continuous magnetic layer is contained therebetween,
