Abstract: A pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer, at least a surface (α) of the resin layer being opposite to the side of the substrate or being opposite to the side which the release material is provided, having pressure sensitive adhesiveness, the surface (α) having one or more concave portions, the concave portions having irregular shapes. The pressure sensitive adhesive sheet has an excellent air escape property capable of easily removing air accumulation that may be formed on attaching to an adherend, and is excellent in pressure sensitive adhesion characteristics.

Abstract: Provided is a pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer formed of a multilayer structure of three or more layers including a fine particle-containing layer that contains fine particles in an amount of 15% by mass or more, at least a surface (α) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided having pressure sensitive adhesiveness, wherein the fine particle-containing layer is formed not as the outermost layer of the resin layer, and one or more concave portions exist on the surface (α) and the shapes of the one or more concave portions have irregular shapes. When attached to an adherend, the pressure sensitive adhesive sheet can exhibit excellent air escape property of readily removing air accumulation which may be formed, good blister resistance and good pressure sensitive adhesion characteristics.

Abstract: Provided is a pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer that includes a resin part (X) containing a resin as a main component, and a particle part (Y) consisting of fine particles, at least a surface (α) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided having pressure sensitive adhesiveness, wherein plural concave portions having a maximum height difference of 0.5 μm or more exist in a predetermined region (P) on the surface (α), and 95% or more of the plural concave portions existing inside the region (P) have shapes differing from each other, and one or more such concave portions exist in a predetermined region (Q) on the surface (α). When attached to an adherend, the pressure sensitive adhesive sheet can readily remove air accumulation to be formed and therefore exhibits excellent air escape property, and has good blister resistance and pressure sensitive adhesion characteristics.
