MULTILAYER ELEMENT COMPRISING MICROLENSES |
摘要 |
Described is a multilayer body for representing microimages provided with gray value gradations or color gradations. The multilayer body has a transparent first layer in which a plurality of microlenses are shaped, and a second layer (61) which is arranged beneath the first layer and has a plurality of microimages. The microlenses are arranged in accordance with a microlens raster. The second layer has a plurality of microimage regions (61b) arranged in accordance with a microimage region raster whose raster width is <300 μm. Within each microimage region two or more of the microimages (61ma through 61mc) arranged in a microimage raster respectively differ from each other, wherein the raster spacings of the microlens raster and the microimage raster differ from each other by less than 10%. The microimages have regions with a gray value or a color value. Also disclosed is a process for the production of the multilayer body. |
