A layered structure comprising in sequence a substrate, a scratch-resistant layer and a covering layer is disclosed. The scratch-resistant layer contains an at least partially cured polycondensate of a first reaction mixture that contains at least one silane, and the covering layer contains a cured polycondensate of a second reaction mixture that contains a silane compound having at least one non-hydrolyzable substituent that carries an epoxy group. The invention finds applicability for the uniform coating of three-dimensional substrates, especially motor vehicle windows.
