发明名称 A laminar compound for transferring optically variable single elements to objects to be protected
摘要 The layer (6) possessing the diffraction structures has the shape of the outline of the element being transferred (2) and rests on the substrate (3) only in parts. The reflecting layer is positioned solely near the diffraction structures and in the form of a metal layer (5) in which are cavities in the form of signs or patterns. The join between layers, between the substrate and the layer possessing the diffraction structures, has a wax-like dividing layer. The layer possessing the diffraction structures is a reaction coating layer of a thermoplastic layer. <IMAGE>
