Abstract: An optical coating structure applied to the surface of an object having scattering structures introduced to the basal, upper or middle layers of a multilayer reflector to cause a particular (calculated) degree of scattering, or to the surface of a black/colour pigmented object. The scattering structures are mainly sub-micron in size, and arranged in a pseudo-random or non-periodic manner. Consequently they serve only to broaden the angular range of the light reflected at the surface normal from a multilayer reflector, or to provide (actual and/or perceived) reduced reflectivity of a surface by deflecting incident light through the surface rather than away from it or by scattering otherwise beam-like (narrow-angle) reflections from a surface into a broad-angle reflection. The scattering structures can include profile elements, which are in the form of elongate bars having convexly curved sides or hemispherical rods, that are introduced to a basal layer of a multilayer reflector.
