FIELD: printing.SUBSTANCE: invention relates to an achromatic security element for valuable documents, such as banknotes, cards, ID documents and similar documents, as well as a method for producing such security elements, valuable documents comprising said security elements. Achromatic security element comprises thermoplastic or radiation-curable polymer layer, where said layer contains embossing from diffusely reflecting non-diffraction microstructures, wherein microstructures have dimensions which are located outside wavelength range of visible light in non-diffraction mode, and provide non-periodicity of surface topography, so that incident light is diffusively reflected or scattered on statistical surface inhomogeneities.EFFECT: disclosed is a achromatic security element for valuable documents.19 cl, 4 dwg
FIELD: printing.SUBSTANCE: protective element has an upper side, on which there is a microcavity structure, having a plurality of adjacent microcavities, on which is there is a structure causing a colour effect, having a dispersion depending on angle of incidence. Microcavities are made for a given range of angles of incidence of rays on upper side of ±10° or more, in form of retroreflectors, having a first section in which are reflected rays incident on upper side at an angle within said range of angles of incidence, singly, and a second section in which are reflected rays incident on upper side at an angle within said range of angles of incidence, repeatedly, so that as a result of dependence of dispersion on angle of incidence, having a structure causing a colour effect, rays incident on first section at angle within said range of angles of incidence, and singly reflected thereby, when viewed from upper side, cause a different colour effect than rays reflected multiple times at second section.EFFECT: disclosed is a protective element for making security documents, such as banknotes, cheques or similar.14 cl, 15 dwg
FIELD: printing.SUBSTANCE: invention relates to a security element for counterfeit-proof papers, valuable documents or other data media with substrate, which on the surface section has optically variable surface pattern, which with a different direction of illumination and/or viewing creates various images. Optically variable surface pattern is formed by multiple facets, substantially operating according to laws of beam optics, where dimensions of said facets are, at least in one direction of plane of surface section, less than 30 mcm and arranged aperiodically in plane of surface section.EFFECT: disclosed is a security element for valuable documents.18 cl, 7 dwg
FIELD: information technology.SUBSTANCE: invention relates to data media type identification card based on multilayer polymer films and can be used in making documents, credit cards and identification with colour solution components thereof. Method of recording information in multilayer carrier based on metallized layers which are sensitive to laser radiation involves exposure to laser light color metallised layers based on films of metals extraction areas of different colour characteristics, identification of areas exposed to laser radiation on the data medium in accordance with the colour characteristic of the defined areas, determination of size rastering element and focusing the laser beam in accordance with the size rastering element scanning laser region exposed to laser radiation, recording information engraving metallised layer laser pulses with energy corresponding graduations colour characteristics of the selected region in information field, note here that every rastering element to the depth arrangement color-forming-coated layer by removal of metal material overlying metallized layers within rastering element laser ablation, and the area of the specified colour characteristics of the displayed through rasters turn of each raster in the plane of the corresponding metal-coated layer.EFFECT: invention provides higher information value and degree of protection of documents.8 cl, 8 dwg
