Grating image with Wölbeffekt

The invention relates to a grid image (20) for displaying an appearing with a shimmering three-dimensional Wolbeffekt motif (14) having a peripheral contour (30), the grid image (20) comprises a diffractive grating structure (22) having a plurality of straight and / or curved grating lines (28) and generates the subject under illumination for a viewer (14) with the three-dimensional Wolbeffekt shimmering. According to the invention it is provided that the diffractive grating structure (22) into a plurality of partial elements (24) is divided, each with continuous grid lines (28) are filled and from each other by less than 100 microns long and transverse to the grating lines (28) extending separating regions (26) are separated, and that the continuous grating lines (28) are arranged in the partial elements with stepwise varying intervals and with irregularly interspersed grid line defect (32).
