摘要： The present invention relates to the field of methods for producing eye-catching overt security features exhibiting one or more indicia as anti-counterfeit means on security documents or security articles as well as decorative purposes. In particular, the present invention provides methods for producing security features that can be easily, directly and unambiguously authenticated by the human without any external device or tool, wherein said security features comprised a cured UV-Vis radiation cationically or hybrid curable coating composition and cured one or more indicia, said composition comprising an ink vehicle and pigments comprising a flake-shaped non-metallic or metallic substrate comprising one or more at least partial coating layers, an at least partial surface treatment layer made of one or more surface modifiers based on perfluoropolyethers.

摘要： A security element for documents of value or the like, has a substrate which has been coated with a heat-sealing adhesive that is non-tacky at room temperature and suitable for applying the security element to a substrate of a document of value. The heat-sealing adhesive contains a radiation-crosslinkable component and a reactive diluent.

摘要： There is described a multilayer optical thin film structure comprising multiple optically absorbing layers and multiple optically non-absorbing layers. The optically absorbing layers and the optically non-absorbing layers are configured such that light incident on the structure is reflected with a red colour at a first angle, and light incident on the structure is reflected with a yellow colour at a second angle. There is also described an item having applied thereto such a multilayer structure.

摘要： Methods and systems for a financial card with dynamic viewing angles are disclosed. A first portion of indicia and a second portion of indicia can be disposed on a first surface and/or a second surface of a financial card. The first portion of the indicia can be viewable only from at least a first viewing angle. The second portion of the indicia can be viewable only from at least a second viewing angle, the second viewing angle being different from the first viewing angle.

摘要： The present invention particularly relates to a method for physical vacuum deposition of a coating (R) comprising at least one material (M) on at least a portion of a front face (10) of a support (1), said at least one material (M) originating from an evaporation source or an atomisation source (2), wherein: —use is made of a support (1), at least a portion of the front face (10) of which is smooth, that is to say, does not have any roughness and/or reliefs and/or recesses; —said vacuum deposition is carried out while varying the thickness distribution of the material (M) on said front face (10), that is, while progressively varying the thickness deposited, from a central region (11) in the direction of at least one lateral region (12) contiguous to the central region (11), without modifying the position of the evaporation source or atomisation source (2) of the material particles (M).

摘要： An encoding element and an anti-counterfeiting product. The encoding element includes a printing stock, wherein the printing stock has an encoding area thereon; the encoding area is provided with at least one group of markers, and at least one of the attributes of markers in the same group is the same; and the markers are randomly distributed, such that encoding information of the encoding element is random. By means of the disclosure, an encoding system of “one object, one code” is realized, and the uniqueness of encoding is realized by means of random encoding information, which cannot be preset.

摘要： A substrate is printed with front side and back side markings in a first color ink. The front side when viewed with reflected light includes a first marking printed in a first saturation and a first symbol printed in the first saturation. The back side when viewed with reflected light includes: a second marking printed in a second saturation; a second symbol printed in the second saturation; a third marking printed in the first saturation; and a third symbol printed in the first saturation. The first marking, the second marking, and the third marking are printed to provide an interlocking pattern of low saturation color and high saturation color when viewed with transmitted light. The second symbol is visible, and the first symbol and the third symbol are visible and indistinguishable, when viewed with transmitted light.

摘要： An optical security element made of a refractive transparent or partially transparent optical material and comprising an optical assembly of a caustic layer having a light-redirecting surface with a relief pattern of given depth and a focal length fC and an adjacent lens element of focal length fL configured to redirect incident light received from a point-like light source through it and to form a projected image containing a caustic pattern directly on a retina of an observer. A marked object, as well as a method of visually authenticating an object, and use of optical security elements for authenticating or securing against counterfeiting are also disclosed.

摘要： Provided are: a light diffraction layer laminated sheet which enables easy production of a card that has a light analysis structure; and a card. A light diffraction layer laminated sheet material which forms a part of a laminated structure of a card by being laminated on top of a card base material. This light diffraction layer laminated sheet material is provided with: a transparent sheet layer; a hologram layer that has a contour smaller than the contour of the transparent sheet layer and is laminated on one surface, which is the upper surface, of the transparent sheet layer; and an HS layer that bonds the transparent sheet layer and the hologram layer with each other.
