摘要:
A capsule placed on a beverage bottle. The capsule includes a capsule material layer and at least two layers of security ink on the capsule material layer. Each of the at least two layers has a different chemical composition. At least one layer of the at least two layers includes a first composition having flakes exhibiting full reflection of light received at a predetermined wavelength.
摘要:
A display (10) according to the present invention comprises a first optical effect layer (12) including a first interface part (IF1), the first interface part being provided with recesses or protrusions arranged two-dimensionally at the minimum center-to-center distance in a range of 200 nm to 500 nm, each of the recesses or protrusions having a forward-tapered shape, a reflective material layer (13) covering at least a part of the first interface part (IF1), and a second optical effect layer (17) including, at a position of a first portion of the first interface part (IF1) that is covered with the reflective material layer (13), a portion that faces the reflective material layer (13) with the first optical effect layer (12) interposed therebetween or faces the first optical effect layer (12) with the reflective material layer (13) interposed therebetween, the second optical effect layer containing at least one of a cholesteric liquid crystal, a pearl pigment and a multilayer interference film. The display (10) achieves a higher forgery prevention effect.
摘要:
Die Erfindung betrifft ein Durchsichtssicherheitselement (12) für Sicherheitspapiere, Wertdokumente und dergleichen mit zumindest einer Mikrostruktur mit einem in Durchsicht betrachtungswinkelabhängigen visuellen Erscheinungsbild (26, 28). Erfindungsgemäß ist die zumindest eine Mikrostruktur aus einer Anordnung einer Vielzahl von Strukturelementen (24) mit einem charakteristischen Strukturabstand von 1 µm oder mehr gebildet und das Durchsichtssicherheitselement (12) weist eine Gesamtdicke von 50 µm oder weniger auf.
