The present disclosure is directed towards a security sheet () for displaying personal data () comprising a plastic substrate () comprising first and second outer surfaces (). A first opaque region () extends partially across the plastic substrate () between the first and second outer surfaces (). A first window () is at least partially surrounded by the first opaque region (). A security device () comprises a transparent first device region () and a second device region () formed from a second device insert (). The first and second device regions () have different optical detection characteristics. The security device () is arranged in the plastic substrate () such that, when viewed in reflected light incident upon the first outer surface (), at least part of the first device region () is visible at least partially around the second device region () in the first window ().

Security sheet

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

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

Security sheets comprising security elements

A security device comprises two or more regions (). Each region () 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.

Security device and its production method

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.
