摘要： A security device includes a substrate and a photoluminescent image on or in the substrate. The image includes at least two different visible light emitting photoluminescent quantum dot compositions, each arranged according to different respective photoluminescent sub-images. The at least two different visible light emitting photoluminescent quantum dot compositions have different emission spectra from one another, and the same or different excitation spectra. The at least two different visible light emitting photoluminescent quantum dot compositions emit different respective visible colours from one another when excited. The respective photoluminescent sub-images are configured such that the photoluminescent image formed by the combination of the respective photoluminescent sub-images is multi-coloured, emitting different visible colours in different laterally offset parts thereof upon excitation of the at least two different visible light emitting photoluminescent quantum dot compositions. At least a portion of the photoluminescent image overlaps an at least semi-transparent region of the substrate.

摘要： A method of manufacturing a security device is provided. The method comprises providing a substrate, the substrate having opposing first and second surfaces and a relief structure formed in the first surface of the substrate. A reflection enhancing layer is applied over the first surface of the substrate such that the reflection enhancing layer at least partially overlaps the relief structure and such that a first region of the first surface of the substrate does not have the reflection enhancing layer. An absorber layer is applied over the reflection enhancing layer such that the absorber layer at least partially overlaps the reflection enhancing layer and the relief structure where the reflection enhancing layer and the relief structure overlap each other, and such that the absorber layer at least partially overlaps the first region of the first surface of the substrate. An optical spacer layer is applied over the absorber layer such that the optical spacer layer at least partially overlaps the absorber layer, reflection enhancing layer and the relief structure where the absorber layer, reflection enhancing layer and the relief structure overlap each other, and such that the optical spacer layer at least partially overlaps the absorber layer and the first region where the absorber layer and the first region overlap each other. A reflector layer, formed of an at least partially reflective material, is applied over the optical spacer layer such that the reflector layer at least partially overlaps the optical spacer layer, the absorber layer, the reflection enhancing layer and the relief structure where the optical spacer layer, the absorber layer, the reflection enhancing layer and the relief structure overlap each other, and such that the reflector layer at least partially overlaps the optical spacer layer, the absorber layer and the first region where the optical spacer layer, the absorber layer and the first region overlap each other. The reflection enhancing layer and the absorber layer are formed of the same material. The absorber layer, the optical spacer layer and the reflector layer, together, form a colour-shifting structure. The reflection enhancing layer and the absorber layer, together, are substantially opaque or transmit less than 40% of incident light, preferably less than 20% of incident light.

摘要： A method of manufacturing a pattern on a substrate web includes providing a production tool having a surface relief structure of elevations and depressions. The elevations correspond to a desired pattern. A curable material is applied to the elevations. The material is brought into contact with a substrate web at a first location. The substrate web and surface relief structure are transported together in contact from the first location to a second location spaced from one another along the transport direction of the substrate web. The substrate web is separated from the surface relief structure at the second location whereupon the material forming the pattern is affixed to and carried by the substrate web. The material is cured by exposure to a curing energy source, either between the first and second locations and/or after the substrate web has been separated from the surface relief structure at the second location.

摘要： A method of producing a security device comprises providing a substrate having a relief structure in/on its surface, the structure provided in a first region of the substrate. The structure in the first region a first recess or a plurality of first recesses in/on the surface of the substrate, the first recess or recesses being recessed with respect to one or more corresponding first land areas of the first region in/on the surface of the substrate. Further comprises applying a colour-shifting coating structure to the relief structure that the colour-shifting coating structure received in the first recess or recesses of the first region and on one or more first land areas. The colour-shifting coating structure applied wherein a thickness of the colour-shifting coating structure in the first recess or recesses is greater than or less than a thickness of the colour-shifting coating structure on one or more first land areas.
