Abstract
The present invention relates to an optical component having a crosslinked anti-fog coating obtainable by covalent attachment of a silane derivative of the formula (2) to the surface of the optical component and crosslinking of adjacent molecules:RXSiB  (2)whereinm=1 to 3, n=1 or 2 and o=0 or 1, with the proviso that m+n+o=4;the radical X is selected from halogen or C-alkoxy, andfor m=2 or 3 the individual radicals X may be identical or different,the radical R is C-alkyl,the radical B has the structure -B1-B2, in which -B2 is a terminal hydrophilic group which is crosslinked to at least one hydrophilic group of an adjacent molecule of the anti-fog coat, and -B1- represents either a spacer group, which joins the hydrophilic group B2 to the Si atom, or a covalent bond,where the terminal hydrophilic group -B2 is poly(meth)acrylate, and for n=2 the individual radicals B may be identical or different.
