<p>The reflector film comprises a layer of transparent plastic material, embossed on two sides, in which a first embossed side exhibits a distribution of spherical first micro-convexities (3) and a second embossed side, destined to be in view and exhibits a distribution of spherical second micro-convexities (4) having a smaller degree of curvature than the first micro-convexities (3). A coat (5) of reflecting material covers the first embossed side. Each micro-convexity (4) on the second embossed side corresponds and is coaxial to a micro-convexity (3) on the first embossed side. The film is highly reflective.</p> |
