Zusammenfassung:A friction surface sheet material which may be adherently bonded to the patterned surface of a substrate which permits the visual observation of such pattern when attached. The friction surface sheet material comprises a backing layer formed of a dimensionally stable polymeric film such as polyethylene terephthalate. A first and second coating of the first and second transparent binder material adherently bond a multitude of minute transparent glass particles uniformly dispersed over the upper major surface of the backing layer, with the tops of the glass particles projecting above the binder coating to provide a friction surface, and the bottom major surface of the backing layer has thereon a layer of transparent pressure-sensitive adhesive. The glass particles may be glass spheres or fragments obtained by fracturing larger particles of glass. The transparent sheet material of the invention is particularly suited for applying to the surface of skate boards, particularly those which have ornamental surfaces which the owners desire not to obscure.
