摘要 Identity document and also method for producing said identity document. Such a document or bank card is provided with a hole pattern acting as a security feature, for example depicting the face of the rightful holder of that document. In order to prevent cracks or other damage at the position of the hole pattern, it is proposed that a tissue layer be placed at that point. The tissue layer consists of a tissue web made up of intersecting multifilament threads. If a staggered grid pattern of the perforation has to be obtained, the thread directions preferably extend at an angle of approximately 60 or 90°.
