发明名称 OPTICALLY VARIABLE SURFACE PATTERN
摘要 The invention relates to an optically variable surface pattern which is divided into at least three sub-areas (8-11) having respectively several pixel sections (4-7). A first and a second sub-area reproduce two different perspectives of a first pattern when pivoting about a first axis and dependent on the viewing angle, and a third sub-area reproduces another perspective of the first pattern or another perspective of a second pattern when pivoting about a second axis which is not parallel to the first axis, whereby the first and second sub-areas reproduce the two different perspectives such that a three-dimensional image impression is produced for the observer.
