Zusammenfassung:	Scratch resistant and antireflective coatings for synthetic resins, said coatings having a refractive index differing from the value 1.45 by at least 0.01 unit and a thickness ranging from 1 to 40 microns and comprising (1) (a) an acrylate and/or methacrylate polymer, and/or (b) an organosilicon polymer, or (c) a melamine resin; and (2) from 0.1 to 10 weight percent of amorphous, porous silicic acid having a large pore volume from 0.1 to 5 ml/g and consisting of primary particles of an average diameter ranging from 1 to 50 microns; synthetic resin substrates having such a coating thereon; coating compositions for applying such a coating to a substrate; and methods for making such coatings.
