ABSTRACT:
An abrasion resistant coating for a substrate, particularly a transparent polymeric substrate or a metallic substrate, includes a cured inorganic/organic hybrid network material formed by a sol-gel co-condensation of at least one metal alkoxide and a silane-functionalized organic compound, wherein the silane-functionalized organic compound is a di- or triamine (such as, for example, diethylene triamine and 3,3'-iminobispropylamine), an aliphatic diol (such as, for example, ethylene glycol, 1,3-propanediol, 1,4-butanediol and 1,5-pentanediol), an aromatic diol (such as, for example, hydroquinone) or a triol (such as, for example, glycerol), functionalized by a silane-functional compound.
