An element comprises a support, preferably a continuous polymeric film, and fibrous material, preferably a spun glass fiber web, which is secured to the support and protrudes therefrom, the protruding fibrous material being part of a layer comprising randomly distributed fibers having solid material, especially particulate material, adhered thereto. The element can be prepared from a composition containing solid material dissolved or dispersed in a liquid medium by applying said composition to fibrous material which is partially embedded in one surface of a support and then drying to evaporate the liquid medium.
