Abstract
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.

A pressure-sensitive adhesive sheet structure having relocatable properties comprising a pressure-sensitive adhesive layer and a layer of non-adhesive solid particles;
- said solid particles having a diameter smaller than the thickness of the adhesive layer and an average diameter of less than 10.mu. and said solid particles in said layer being randomly but uniformly distributed over the surface of the adhesive layer, wherein the ratio of the thickness in .mu. of the adhesive layer to the average diameter in .mu. of the solid particles is at least 2.
