Abstract (en)

[origin: EP3015278A1] The invention relates to the field of counterfeit protection of products made on a paper carrier or on a polymer carrier, and is intended for visual verification of the authenticity of protected printed products. A product, for instance, a valuable document, comprises a carrier and a multilayer security element containing a latent image. The security element is indiscernible when the document is viewed at the right angle to the surface thereof, but becomes visible when the angle of viewing changes. The latent image is comprised of two identical graphical elements of different color, which are formed by means of mutual offset of portions of a three-dimensional raster and of a raster of a multicolor cover by a distance multiple of half the period of the raster, and which are positioned in a single plane relative to each other. The elements are disposed at a distance which allows for viewing a stereoscopic image thereof by using anaglyph glasses and/or color filters. The technical result is an increased level of protection of a valuable document.
