FIELD: optical devices, baffle coating, possibility to produce clothes with baffling features, and advertising boards. SUBSTANCE: light reflecting material consists of sequence of layers, which include white diffuse reflection layer, optical transparent intermediate layer, layer of small-size lenses providing raster, and protection layer. Reflecting layer is located in focal plane of raster. Optical height of protection layer is less than optical height of raster. EFFECT: possibility to copy spectral properties and structural characteristics of light dispersed from substrate surface in wide three-dimensional angle. 1 dwg
