| 摘要 |
<p>The present invention relates to an optically variable surface pattern having a substrate that comprises a first and a second surface region, the two surface regions being developed in such a way that the first surface region presents, in a first solid angle range (α1) a bulged-appearing first view, and the second surface region presents, in a second solid angle range (α2) that is different from the first solid angle range (α1), a bulged-appearing second view.</p> |
