Abstract

According to the invention, a surface pattern (1) has N visually recognisable patterns consisting of diffractionally effective, microscopically fine relief structures or flat reflective surfaces, or comprising absorbent or dispersive structures. The N patterns together contain at least one common independent surface element (11). Said surface element (11) is divided into surface parts, said surface parts being arranged in a predetermined structure which is independent of the N patterns. Said arrangement of the surface parts is not visible to the naked eye. Each surface part is covered with an individual, microscopically fine diffraction structure or alternatively, a structure which has an absorbent or dispersive property or which is a flat reflective surface. The relief structures, diffraction structures and other structures are embedded in a plastic laminate (20) and the optical effect of said structures can be increased with a reflective layer (21). The surface pattern (1) is applied to a document (2) as a security element and enables said document to be recognised by machine in a reading device.
