Abstract
A valuable document with an optically variable structure that attests to the authenticity of the document is proposed, which comprises a coating in the form of a printed raster, and a three-dimensional raster formed on a transparent material and arranged relative to the coating so that the three-dimensional raster is at least partially disposed thereon, the width of the lines and the distance between the lines of the printed and the three-dimensional rasters as well as the mutual orientation of the rasters being selected so that a coloured moire pattern is visible in the event of a change in the viewing angle, wherein at least a portion of the lines of the three-dimensional raster has an asymmetric cross-section profile with an aspect ratio of not less than 1 : 1.25, forming a latent image, as a result of which, in the event of a 180 DEG change in the viewing direction without any change in the viewing angle, the latent image becomes visible against the background of a multi-coloured moire pattern owing to a change in the colour gamut of that part of the moire pattern which lies in the region of the lines with an asymmetric cross-section profile. At the same time, if the viewing angle is changed, the apparent movement of the boundaries of the coloured moire pattern results.

While observing file with an angle in the plane of the direction perpendicular to three-dimensional grating lines (9a), can see yellow, blueness, purple Moire fringe.When file tilts with respect to position (9a) (9c), Moire fringe seems to move along horizontal direction.When file Rotate 180 is spent (9b), colour gamut as Moire fringe image becomes result orange, green, purple, the hidden image forming in the region of the asymmetric lines profile of having of three-dimensional grating becomes visible, and when file tilts (9d), Moire fringe also seems along horizontal direction, to move.
Example 4(Figure 10 and Figure 11)
As shown in Figure 10 and Figure 11, value document is produced in paper substrates (16), and comprise the printing grating (19) being formed by the dull and stereotyped version printing of dichromatism---wherein, like color class for light grey---and the three-dimensional grating (17) that uses intaglio printing to apply by blind blocking, the lines of three-dimensional grating are with respect to the angles of printing grating lines rotation 17 degree.Printing grating comprise have constant equal width, by identical grey but there are the equally spaced lines that replace that two kinds of inks of different ultraviolets and infrared attribute form, and when watching with normal optical, grating is visually perceived as monochromatic areas (11a).When being exposed to the ultra-violet radiation of wave-length coverage 330nm to 370nm, ink has different glow colors, and in wave-length coverage 700nm to 1100nm, has different INFRARED ABSORPTION attributes.Under ultra-violet radiation, the first ink is sent out red fluorescence, and the second ink green-emitting fluorescence.The first ink has wide absorption spectrum in wave-length coverage 700nm to 1100nm, and the second ink selectively absorbs in scope 700nm to 860nm.
Three-dimensional grating comprises the lines that replace with same thickness, but interval between lines is the twice of the width of lines.
A part for three-dimensional grating forms (18) with the lines of 90-degree rotation, and these lines form hidden image.When watching file at any angle in normal optical, in the region with security feature (11c, 11e), observe monochromatic light grey image pixel.
While observing file with right angle under the ultraviolet light at 365nm, in the region of security feature, observe the pictorial element of jaundice coloured light.When observing file with angle (11b), in the region of security feature, observe green More alternately and be with red More and be with.When file Rotate 180 is spent (11c), as there is not the true result of Moire fringe in hiding elemental areas, can see hidden image.
When watching file with right angle in infrared viewer, observe monochromatic gray area.When observing file with an angle in infrared viewer in scope 810nm (11d), the black Moire fringe replacing is visible.When file Rotate 180 is spent (11e), owing to there is not the fact of Moire fringe in hiding element, it is visible that hidden image becomes.
When watching file with an angle in infrared viewer in scope 940nm, the black region without Moire fringe is visible.
Industrial applicibility
