Abstract

A reflective material (1) comprises a carrier sheet (2) with a finely embossed surface, a thin reflective layer (3) deposited on the surface and of a thickness such that the exposed surface of the film follows the contours of the embossing, and transparent microparticles (4) received within the recesses of the reflective film and bonded thereto. <IMAGE>
