<p>Curable compositions essentially comprise a selected class of starting compounds and a selected class of particulate metallic oxides as electrically conductive components, the oxides being coated with a selected class of hydrolyzed silicon compounds of the formula R1_mR2_nSi(OR<3>)4-(m+n) where R<1> and R<2> each are a hydrocarbon moiety of 1 to 20 carbon atoms or an organic group containing a halogen atom or an epoxy, acrylonitrile, methacrylonitrile, mercapto or amino group, each of the hydrocarbon moiety and organic group forming a Si-C bond, R<3> is a hydrocarbon moiety of 1 to 6 carbon atoms or an oxygen-containing hydrocarbon moiety, m and n each are 0, 1 or 2, and the sum of m and n is 1 or 2. The resulting cured coating excels in transparency, abrasion resistance, adhesive strength and electrical conductivity.</p> |
