1. Method for controlling the UV absorption properties of metal oxide-containing UV filter layers, whereA) a layer comprising an organometallic compound is applied to a substrate and converted into a layer comprising a metal oxide or a metal mixed oxide at a temperature in the range from >

  • 230°

    C. to 500°

    C., and/orB) an organometallic compound is applied to a substrate and converted into a metal oxide or metal mixed oxide and where the application and conversion takes place a number of times successively with formation of multilayered systems comprising metal oxides and/or metal mixed oxides and the organometallic compound for an individual layer is applied in a solution or dispersion comprising same in a concentration which reduces with increasing total number of layers in the multilayered systems, where the concentration in each of the individual layers is the same within a single multilayered system.
