Abstract

The piece shows its identity with visible light. Especially Safety parts For valuable documents such as bank cards, credit cards, passes or checks, anything else that needs to be kept secure. Containing A carrier with a visible reflective surface and a thin layer of metal coating onto the carrier's visible surface. And which has a surface that appears It is a shiny metal in which viewing angles have been developed in such a way that Thing with that piece It is more effectively prevented from counterfeiting than possible optical display parts. Has been designed so that the visible surface of the carrier has two carrier regions with a level of reflection Differential light at the corresponding sub-regions or the many sub-regions of each carrier region, both of them are coated with metal, and at the reflections of the metal coating in the direction of view outside the range of the angle Looking Is lower than the reflection of the carrier area with a high level of reflection. Or clearly equivalent and is significantly higher than the carrier region reflection with low or equivalent reflection levels. And has a higher value than the Reflection of the carrier region with a low reflection level Or equivalent Clearly
