The thickness of the layer, susceptible to paint, within the second section of the base in stepped or stepless manner is decreased starting from the first thickness of the layer, susceptible to paint, which it has on the first section of the base, down to the minimum value.EFFECT: invention provides creation of the fraud-proof paper on which it is possible to apply the printing image with simultaneous providing the recognisability of optically variable effect created by the protective element located in paper which has optically variable properties.16 cl, 4 dwg
FIELD: process engineering.SUBSTANCE: invention relates to the element intended for fabrication of file or info panel. This element represents an incomplete article, initially flat and composed of the substrate of one or more flat sheets and coating secured there over or around. Note here that hot adhesive ply is applied on one side of said substrate to extend to spacing (D) from the substrate edges for finish coating or poster or the like element to be secured at said side. Said element made, the substrate is composed of the completely flat continuous sheet with coating. Note here that hot adhesive ply is applied on one side of said substrate to extend to spacing (D) from the substrate edges for finish coating or poster or the like element to be secured at said substrate side smaller than the substrate periphery.EFFECT: perfected design.20 cl, 10 dwg
FIELD: physics.SUBSTANCE: protective element comprises a transparent base layer and a partially reflecting layer on the base layer. The element also comprises a transparent filling layer on the reflecting layer. The reflecting layer in the subject region is structured to form multiple partially transparent micromirrors which, owing to directed reflection of incident light when viewing the subject region from above, demonstrate a distinguishable subject. The refraction indices of the base and filling layers in the visible spectrum differ by not more than 0.2, so that the subject which is distinguishable when viewed from above cannot be recognised when the subject region is viewed through.EFFECT: obtaining an optically variable protective element with high counterfeit protection with high recognisability and improved verification.19 cl, 15 dwg
FIELD: physics.SUBSTANCE: claimed component visible at reflection comprises prominent structure. The latter is made on the substrate with refractive index n0. It comprises also the thin ply of dielectric material some 50-150 nm in depth with refractive index n1 other than n0 applied on prominent structure, and the ply of material with refractive index n2 approximating to n0, and encapsulating structure coated with thin ply. Said structure comprises the first and second patterns, the latter simulating the former that make the low relief including the set of facets, their shape simulating the low relief of prominent object. The second pattern makes the periodic grating simulating the first patter so that after application of thin ply and structure encapsulation the first colour can be produced at the angle of observation and second colour at the second angle of observation by azimuthal turn of the component.EFFECT: better identification and memorization owing to colour variation subject to direction of observation and visual effect of 3D relief.15 cl, 16 dwg
FIELD: printing.SUBSTANCE: invention relates to polymeric multilayer products, in particular to polymeric protective elements used for visual authenticity control of security printing products, such as securities, banknotes, passports and ID documents. The element for authenticity control of security printing products is applied to the substrate and has modified paint areas resulting from exposure to laser radiation on the paint layer to form the image detectable by visual control. The paint layer comprises microparticles ranging in size from 1 micron to 100 microns, coated by thin-film transparent, half-transparent or interference paint layers or microvoids containing pigments or dyes in them. The said microparticles or microvoids are arranged regularly and oriented. The images formed by modified paint areas are made by the laser radiation incident on the paint layer at different angles.EFFECT: enhanced counterfeit protection of valuable documents.6 cl, 1 dwg
FIELD: physics.SUBSTANCE: fibrous material is composed of the mix of separate polymer 0.1-10 mcm diameter fibres containing luminophor and arbitrarily interwoven micro fibres as separate fibrous particles of linear sizes of up to 200 mcm. Preferably, this material contains organic and/or inorganic UV- or IR-luminophor that acquires the luminescence colour under UV radiation at temperature variation. Fluorescent semiconductor nanoparticles can be used as said luminophor. Claimed material is produced by electrostatic moulding from fibre-forming polymer solution in organic solvent containing luminophor. Then, fibres are minced in water to dispersion of micro fibres. Invention discloses also the claimed paper protected against counterfeit comprises abode described fibrous material and the article thereof.EFFECT: better protection, higher strength and wear resistance.13 cl, 2 dwg, 4 ex
