The present disclosure is directed towards a security sheet (11) for displaying data (16). The security sheet (11) comprises a data sheet (15) for displaying data (16) and an attachment layer (17). The attachment layer (17) comprises a plurality of tabs (25) extending from an attachment portion (26) for attaching the data sheet (15) into a security document (10). The plurality of tabs (25) are attached to the data sheet (15) such that the attachment layer (17) is attached to and extends from the data sheet (15). The attachment layer (17) can comprise a textile.

A security element including: a first layer having a first surface; an array of image regions across the first surface arranged along at least a second direction, each region including at least a first image sub-region having an average inclination defining an angle, relative to a plane of the security element, about an image region axis extending along a first direction; a diffractive optically variable effect generating structure provided in or on the first surface across the first image sub-regions, the structure including diffractive elements that extend along a direction within 45° of the first direction, wherein the structure is provided across the first image sub-regions and spatially arranged and/or modulated across the first image sub-regions in accordance with a first image so the first image is displayed by the first image sub-regions in combination at least at a first viewing angle. Also, a method of manufacturing the security element.

An optical display body (1) is provided with: a stripe mask (10) that includes a transmission part (T) and a reflection part (R) that is wider than the transmission part, a transmission part and a reflection part which are alternately arranged so as to form a stripe pattern; and a printed body (20) that includes a flattened design (21A) which is a visible image (21B) flattened in a Y direction and which is printed two or more times repeatedly in an X direction. The stripe mask, upon being superimposed on the printed body such that a stripe direction of the stripe mask will be coincident with the X direction of the printed body, allows a visible image to be displayed through the stripe mask.

An inlay sheet for a book-like identification document. The inlet sheet may include a first hinge layer comprising polycarbonate and a second hinge layer comprising a flexible material different to polycarbonate, e.g. PET, polyurethane, fabric, mesh. The second hinge layer is attached to the first hinge layer. A first datapage layer and a second datapage layer are attached to the first hinge layer and the second hinge layer, respectively, such that the first and second hinge layers are positioned between the first and second datapage layers for forming a datapage section haying a datapage thickness. The first and second datapage layers form a common datapage inner front edge and the first and second hinge layers extend beyond the common datapage inner front edge such that a hinge section is formed having a hinge thickness smaller than the datapage thickness.

A security device includes a diffractive structure, including grating elements and having a first area, the grating elements within a region have a constant pitch or spacing; the first area regions pitches or spacings increase from one region to the next between a first region having a grating element pitch or spacing of less than or equal to 0.6 microns and an end region having a grating element pitch or spacing of greater than or equal to 5 microns; upon illumination and viewing along a first viewing direction substantially orthogonal to the first axis, the device exhibits a first optical effect in that at least one region exhibits a diffractive colour; each region has at least first and second sub-regions having different grating element orientations within the plane of the device such that the first optical effect is exhibited at more than one angle of tilt about the second axis.

The invention relates to an improved method for the partial coloring, in particular for the color laser engraving, of plastic parts, in particular thermoplastic plastic parts, more particularly thermoplastic plastic parts that have a multi-layered structure, to the resulting partially colored, preferably color laser engraved, plastic parts, in particular thermoplastic plastic parts, and to a device for the partial coloring of plastic parts.

A method for producing a laminated body and a laminating inlay, as well as a laminated body, a laminating inlay and a security document, in particular in the form of a bank card, identity card or credit card, with such a laminated body.
