Patent ID: 8906491

Claim:
A multi-layer body comprising: a replication layer having a first surface defined by a plurality of microscopic pattern regions and a background region surrounding or delimiting completely each of the pattern regions, wherein the pattern regions are arranged in a one-dimensional or two-dimensional grid having a grid width (D) in the range of between 5 μm and 300 μm, and the pattern regions are respectively arranged separated from each other at a spacing (B) by the background region, the ratio of the width (D) to the spacing (B) being in the range of between 5 and 200, and wherein each of the plurality of microscopic pattern regions are formed by a diffractive first relief surface structure shaped in the first surface of the replication layer; and a first metallic layer uniformly disposed on each diffractive first relief structure to form fully metallized microscopic pattern regions, wherein the metallic layer is not applied in the background region to form a fully demetallized background region, wherein the fully metallized microscopic pattern regions form island-shaped pattern regions, which together with the background region, appear as a homogenous metallic surface to the naked eye.
