Abstract:
The invention discloses a security element having a coating layer which appears transparent at certain angles of view, giving visual access to underlying information, whilst staying opaque at other angles of view. Documents of value, right, identity, security labels or branded goods comprising said security element, as well as a method for producing said security element, are also disclosed. Using appropriate substrate surfaces, optically variable and otherwise angle-dependent visual effects can be realized.
