1. An article comprising:
- a substrate;
a graphical component comprising a first ink and forming a background and an image discernible from the background, supported by the substrate; and
, an optical component comprising a second ink, different from the first ink and comprising a plurality of pigment flakes, supported by the substrate;
wherein the pigment flakes each include a magnetic or magnetizable material and are aligned so as to form a frame pattern such that the frame pattern surrounds the image;
wherein, within the frame pattern, along a plurality of radial directions originating at the image, angles which the pigment flakes form with the substrate decrease until a portion of the pigment flakes are parallel to the substrate and then the angles increase so that, when light is incident upon the pigment flakes from a light source, light reflected from the frame pattern forms a dynamic frame which surrounds the image and appears to move as the substrate is tilted with respect to the light source;
wherein the image appears to be stationary when the dynamic frame appears to move; and
,wherein a size and a concentration of the pigment flakes in the second ink are such that a portion of the background adjacent to the dynamic frame is at least partially visible through the optical component.

Abstract
An article includes a substrate and a graphical component forming an image and an optical component which includes magnetic pigment flakes aligned so as to form a frame pattern which surrounds the image. When light is incident upon the pigment flakes from a light source, light reflected from the frame pattern forms a dynamic frame which surrounds the image and appears to move as the substrate is tilted with respect to the light source. The image appears to be stationary when the dynamic frame appears to move.

16. An article comprising:
- a substrate and a multilayered image supported by the substrate,
wherein the multilayered image comprises an indicia, a background pattern, and a coating comprising ink comprising pigment flakes each comprising a magnetic or magnetizable material, wherein the coating is supported by a frame region of the substrate, surrounding the indicia and covering a portion of the background pattern; wherein a cross-section of the coating in the frame region has an arching pattern of pigment flakes, and the arching pattern is maintained along the frame region so that light reflected from the arching pattern forms a dynamic frame which surrounds the indicia and moves relative to the background when the substrate is tilted; and
,wherein a size and a concentration of the pigment flakes in the ink is such that a portion of the background underlying the frame region outside of the dynamic frame is at least partially visible whereby the dynamic frame delimits an indicia-containing dynamic region from the background and the dynamic region moves relative to the background when the substrate is tilted so that the dynamic frame or indicia appears floating out of the plane of the substrate.
