摘要： A security element is provided for a security booklet comprising a plurality of pages including a first outermost page having an inner surface facing the remainder of the plurality of pages and an opposing outer surface, and a second outermost page having an inner surface facing the remainder of the plurality of pages and an opposing outer surface. The security element comprises at least one line of stitching joining the plurality of pages to one another. The stitching is formed of at least a first thread and a second thread, the first thread being disposed on the outer surface of the first outermost page, and the second thread being disposed on the outer surface of the second outermost page. The first and second threads are interlocked with one another at each of a series of spaced apertures through the plurality of pages provided along the line of stitching, and at one or more selected aperture(s), the interlock is configured such that a loop of the second thread extends to the outer surface of the first outermost page. The first thread has an optical characteristic different from that of the second thread, such that the or each loop of the second thread at the selected aperture(s) is optically distinguishable from the first thread.
