A pressure-sensitive adhesive sheet structure having relocatable properties composed of a pressure-sensitive adhesive layer and non-adhesive solid particles; characterized in that the non-adhesive solid particles having a diameter smaller than the thickness of the adhesive layer and an average diameter of less than 10 mu are randomly but uniformly distributed over the surface of the adhesive layer, or are randomly but uniformly distributed and partially or fully embedded in the surface layer of the adhesive layer. |
