Abstract: Disclosed are an optical anti-counterfeiting element and an optical anti-counterfeiting product utilizing the same, the optical anti-counterfeiting element comprising: a substrate (12) including a first surface and a second surface opposite to each other; micro-sampling tools (11) on the first surface; and one or more micro graphic and text units formed on the second surface, wherein the micro graphic and text unit includes micro graphic and text strokes, the micro graphic and text strokes are arranged in a non-periodic and non-fixed-geometry manner, and when the second surface is observed through the micro-sampling tools, a stereoscopic animated anti-counterfeiting feature can be seen.

Abstract: The invention relates to the field of optical anti-counterfeiting, and discloses an optical anti-counterfeiting element and an optical anti-counterfeiting product. The optical anti-counterfeiting element comprises: a substrate which is at least partially pervious to light, comprising a first surface and a second surface opposite each other; an anti-counterfeiting image formed on the first surface of the substrate, wherein the anti-counterfeiting image comprises a plurality of imaging pixel groups, and the imaging pixel groups are arranged aperiodically and/or without an axis of symmetry; and a sampling-synthesis layer with optical characteristics formed on the second surface of the substrate, wherein target visual images corresponding to the imaging pixel groups can be presented through a light-pervious part of the substrate and the sampling-synthesis layer.

Abstract: Disclosed are an optical anti-counterfeiting element and an optical anti-counterfeiting product utilizing the same, the optical anti-counterfeiting element comprising: a substrate (2) having a first surface (31) and a second surface (32) that are opposed to each other, a sampling and synthesizing layer (21) on a first surface (31) of the substrate (2); and a micro-image layer (22) on a second surface (32) of the substrate (2), the micro-image layer (22) including a first region at least partially covered with a coating (221) and a second region comprising at least two sub-regions each at least partially covered with a color function layer (222, 223), the color function layers (222, 223) in respective sub-regions and the coating (221) in the first region have different color characteristics, respectively, and the micro-image layer (22) can be sampled and synthesized by the sampling and synthesizing layer (21) to form an image.

Abstract: An optical anti-counterfeiting element comprises a base material (11). The base material (11) has a first surface and a second surface which are opposite to each other. The first surface is covered thereon with a micro-sampling tool (12); one part of the second surface is a micro image-text formed by a micro relief structure (13), and the other part thereof is a flat structure which does not form a micro image-text and/or a micro relief structure (14) which is different from the micro relief structure forming the micro image-text. The flat structure which does not form the micro image-text and the micro relief structure (14) different from the micro relief structure forming the micro image-text are homomorphically covered thereon with a first plating (15), the micro relief structure (13) forming the micro image-text is homomorphically covered thereon with a second plating (16), and the micro image-text is sampled by the micro sampling tool (12).
