Abstract (en)
[origin: WO2013091819A1] The invention relates to an optically variable surface pattern comprising a substrate which has a surface region (13) having a plurality of reflective pixels (14) arranged in rows and columns and aligned in such a way that when a viewer tilts the surface pattern (10) about a first axis, at least three bright-dark pattern representations are discernible in various positions, resulting in a pattern movement that comprises a movement along a first direction which forms an angle of less than or equal to 30° with the first axis, and/or a pattern rotation, wherein at least one of the rows and/or at least one of the columns contains pixels which produce the bright areas of at least two of the pattern representations.
