A security device includes an arrangement of image icon focusing elements, wherein each image icon focusing element of the arrangement of image icon focusing elements is associated with a focal path. The device further includes an image icon layer with one or more image icons associated with a first characteristic color and one or more image icons associated with a second characteristic color and one or more regions between the image icons comprising a volume of substantially colorless material. At a first viewing angle, a color is visible through each image icon focusing element, and the color visible through each image icon focusing element at the first viewing angle is based on one or more of the first characteristic color, the second characteristic color, or the substantially colorless material.

Use of nanoparticles to tune index of refraction of layers of a polymeric matrix to optimize microoptic (MO) focus

A security device made up of a security film () having (i) an array of image elements (); (ii) an array of focusing elements (); and (iii) at least one anti-viscid agent (), 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.
