A retro-reflective body with an optically perceptible feature includes a substrate on whose upper side a binder layer is disposed. A plurality of transparent elements is at least partially embedded into the binder layer in such a way that light can enter the transparent elements. The surface of the transparent elements is configured as a spherical segment at least in some portions and wherein the spherical segments of the transparent elements are embedded into the binder layer and are orientated towards the upper side of the substrate. The retro-reflective body has a first partial region which a first share of the transparent elements, in each case with the spherical sections, is adjacent at least in some portions to spaces -filled with an optically thinner medium or a vacuum, wherein the optically perceptible feature is formed by the first partial region.
