FIELD: printing.SUBSTANCE: invention relates to a security document with at least partially integrated protective element, and this security document consists of a paper with protection against forgery with two or more layers of the same or various materials. The protective element is made in the form of a transfer element and is applied on the surface of one of the paper layers with protection against forgery, located inside, and this protective element is at least partially coated with at least one more layer of the multilayer paper with protection against forgery, and at least one of the paper layers with protection against forgery has at least one recess through which the protective element is observable.EFFECT: increased protection.29 cl, 5 dwg
FIELD: printing.SUBSTANCE: invention relates to a security element for counterfeit-proof paper, valuable document or the like, a valuable document with such security element and also a method of manufacturing such a security element. The security element comprises a carrier with a surface portion divided into a plurality of pixels, each of which comprises at least one facet generating the optical effect. And most of the pixels have several facets generating the optical effect, having the same orientation on the pixel, and the facets are oriented so that the said surface portion is perceived by the observer as a surface which protrudes forward and/or retreats backwards relative to the actual spatial shape of the surface portion.EFFECT: increase in protection.21 cl, 35 dwg
FIELD: printing trade.SUBSTANCE: invention relates to printing and concerns the fraud-proof paper for manufacture of important documents. The paper contains a base with protective element with optically variable properties distinguished when viewing the base from at least its first side and the layer, susceptible to printing paint, which is located on at least first side of the base and which on its first section outside of the section of location of the protective element with optically variable properties, has the first thickness, and on the second section of the base on which the protective element with optically variable properties is located, has the thickness, smaller in comparison with the first thickness. 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
