  • Patent number: 11912057
    Abstract: A security device made up of a security film (130) having (i) an array of image elements (103); (ii) an array of focusing elements (106); and (iii) at least one anti-viscid agent (115), is provided. The array of focusing elements and the array of image elements are disposed relative to each other such that a synthetic image is projected by the security film when at least a portion of the array of image elements are viewed through at least a portion of the array of focusing elements. The anti-viscid agent is coupled with the array of focusing elements.

  • Publication number: 20180093519
    Abstract: Presented herein are layered systems, security devices formed from the layered systems and methods of manufacturing those layered systems and security devices. The security devices provide several effects including, but not limited to, (1) color-shifting effects that are observable as the points of view of the observant changes and (2) customizable micro-text formed in the security device by demetallization of a metallic layer provided on or within the security device. The method of manufacturing the security devices includes manufacturing a layered system that is used to form the security devices.
