Abstract
Diffuse-reflection surfaces which have a matte appearance and which have self-cleaning properties and preferably have antimicrobial properties, are prepared by coating a substrate with a random distribution of the particles to at least one surface of a substrate, thereby providing a surface comprising elevations with a height of from 20 nm to 100 .mu.m and with a separation of less than 100 .mu.m between the elevations. Such diffuse-reflection surfaces can be used as protective covers or as protective layers, in particular for providing non-angle-dependent viewing. The diffuse reflection surfaces of the present invention have self-cleaning properties and are resistant to colonization by microorganisms.
