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.
