A topcoat layer that has a defined surface structure on an outer surface thereof once the topcoat layer is laminated to a substrate. The surface structure of the topcoat layer provides a matte surface finish to the underlying substrate. Any attempt to alter the substrate or the topcoat layer will result in disruption or destruction of the surface structure of the topcoat layer making such tampering evident. Replication of the surface structure of the topcoat layer by a counterfeiter is also difficult without the appropriate equipment.

The invention relates to composite articles and laminated polymeric materials, for example, paper and plastic-based materials for tokens, and can be used in the manufacture of security articles. An article comprises a disc insert of laminated plastic and an outer metal. The insert includes stacked paper sheets impregnated with a polymer binder. Surface of each sheet is covered with a polymer layer and comprises visual and/or hidden security features. The ring and the disc insert are permanently joined together. At least one of the article components has an embossing. Dimensions of the article are in conformity with the relations: 0.8≤δ2/δ1<1; D1−D2≥8; 0.3≤S1/S2<0.9; D2>16 mm; Δ≤1, where D1 is outer diameter of the metal ring, excluding edge surface, mm; D2—diameter of the disc insert, mm; S1—area of the metal ring, excluding edge surface, mm.sup.2, S2—area of the disc insert, mm.sup.2; δ1—maximum thickness of the metal ring, mm; δ2—maximum thickness of the disc insert, mm; Δ—difference between maximum and minimum protruding elements of the metal component of the article, mm. The article has an enhanced level of security and is simple both in the manufacture and in its authentication.

A security inlay having optically recognizable characters for an identity document comprises a first transparent layer and a second transparent layer. A color coating is situated on the first transparent layer. Furthermore, a first UV color coating, which reflects at least UV light at least in a first wavelength range, is situated on the first layer and/or on the color coating. The first and second transparent layers are connected to one another. A first portion of the optically recognizable characters is formed by blackened sections in at least one of the layers. A second portion of the optically recognizable characters is formed by the color coating. A third portion of the optically recognizable characters is formed by the UV color coating. The first and the second portions of the optically recognizable characters reflect visible light. The third portion of the optically recognizable characters reflects UV light.

A laminate includes a recording layer, a translucent front covering layer and a security foil laminated between the recording layer and the front covering layer and sealed in the laminate. The security foil has a thickness that is ⅕ or less the thickness of the recording layer to prevent or reduce falsification reusing the security foil. The security foil includes a relief layer having a relief surface and a protective layer covering the relief surface. In the thickness direction of the laminate, the protective layer adheres to the recording layer and the relief layer adheres to the front covering layer. The adhesion strength between the security foil and the recording layer is higher than the adhesion strength between the security foil and the front covering layer.
