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.

Abstract: The present invention relates to a method of manufacturing a security sheet comprising a security element (11), a core structure (10) for forming the security sheet, a stack (29) including such a core structure (10), a security sheet comprising the core structure (10) or stack (29) and a security document comprising the security sheet. At least one perforation (20) is formed through, from a first core surface (13) to a second core surface (14) of, at least one core layer (12) comprising plastic. A security element (11) is fed through the at least one perforation (20) such that the security element (11) extends through, from the first core surface (13) to the second core surface (14) of, the at least one core layer (12). At least one first region (17) of the security element (11) is located over part of the first core surface (13) and at least one second region (18) of the security element (11) is located over part of the second core surface (14).

Abstract: A security document includes a first leaf having a first polymer substrate and a first reinforcement layer attached or formed with the first leaf. An outer leaf is attached to the first leaf along a fold line and is located between the first leaf and a cover. The first reinforcement layer extends along the first leaf at least partially along the fold line and at least partially away from the fold line on both sides of the fold line. The security document also has methods of manufacturing such a security document and a plurality of such security documents.

Abstract: A security document and methods of manufacturing are provided. The security document includes a first polymer page adjacent to a second polymer page. The first polymer page has a first polymer substrate and the second polymer page has a second polymer substrate. The first polymer substrate is of a different structure and/or material than the second polymer substrate. The second polymer page is thicker than the first polymer page.

Abstract: The present invention is directed towards a method of manufacturing a security sheet (11) for displaying personal data and a security sheet (11) formed by such a method. The method comprises heating a plastic substrate (14) to an at least softened state. The method further comprises applying a resin (8) to a first and/or second outer surface (15, 16) of the plastic substrate (14) such that the resin (8) fuses with the plastic substrate (14) during the heating step to form at least one raised structure (25). The present disclosure is also directed towards a security document (10) comprising such a security sheet (11) and an apparatus (30) for manufacturing the security sheet (11).

Abstract: An aspect of the invention provides a security device including an array of printed lenses arranged on a first surface of a substrate and a microimage array underlying the array of printed lenses, whereby a synthetic image of portions of the microimages is generated by the lenses. The security device further comprises at least one tactile element arranged on the first surface of the substrate which is of greater or lesser height than the printed lenses, the at least one tactile element being registered to the array of printed lenses.

Abstract: A method of producing a document of value, the method including providing a single lamina or multi-laminate sheet carrying data relating to one or more documents of value; selecting the shape of at least part of the edge of the or each document using the data relating to the document; and operating a cutting tool to cut out the or each security document from the sheet by cutting along the edge of the or each security document such that the at least part of the edge has the selected shape.

Abstract: A process for the treatment of non-keratinaceous textiles, preferably cellulosic fibers, which comprises the step of treating the textiles with a composition which comprises: a self-crosslinking polymer and a nucleophilic species (preferably a polymer comprising at least one protected thiol group), and a textile compatible carrier. Under domestic washing conditions the polymer forms reactive thiol groups which are capable of causing covalent cross-linking with the polymer. Preferably, the thiol group is protected as an isothiouronium group.

Abstract: A security device comprises two or more regions (1, 2). Each region (1, 2) contains a material or combination of materials wherein the two or more regions exhibit substantially the same visible appearance under first viewing conditions and different visible appearances under second viewing conditions, the second viewing conditions. The second viewing conditions comprise a combination of a) visible light and b) substantially any UV wavelength.
