  • Topside optical adhesive for micro-optical film embedded into paper during the papermaking process
    Publication number: 20110130508
    Abstract: An adhesive, micro-contact-lens system [300][400] applied to the topside of microlens arrays [10], which enables films of lens arrays to be embedded into paper during the papermaking process. The optics of the lens array is at least not degraded by the presence of the topside adhesive in areas where the microlens array is selectively exposed at the paper surface. The microlens array is intimately bonded with paper fibers in areas where the topside of the lens array is covered by paper fibers [500], thereby preventing the paper fibers from detaching, rising up or detracting from the otherwise spectacular visual effects enabled by synthetic images displayed by micro-optical films embedded into paper.
