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: An electrically peelable pressure sensitive adhesive sheet has a pressure sensitive adhesive layer formed of an electrically peelable pressure sensitive adhesive composition comprising an acrylic copolymer (A) comprising 1 to 99 mass % of a constituent unit (a1) derived from a compound represented by the following general formula (a1), and a surfactant (B). The electrically peelable pressure sensitive adhesive sheet has high adhesion before voltage application, but the adhesion can be effectively decreased by voltage application for a short time. wherein R1 represents a hydrogen atom or a methyl group, R2 represents an alkylene group having 1 to 5 carbon atoms that is unsubstituted or has a substituent, and R3 represents an alkyl group having 1 to 8 carbon atoms that is unsubstituted or has a substituent; and a value of n is an integer of 1 or more.

Abstract: Provided is a pressure sensitive adhesive sheet containing a resin layer on a substrate or a release material, 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, when a smooth surface of a light transmissive adherend having a smooth surface is attached to the surface (α), one or more concave portion (G) not kept in contact with the smooth surface exist on the surface (α), and the shapes of the one or more concave portions (G) have irregular shapes. The pressure sensitive adhesive sheet has excellent air escape property capable of readily removing air accumulation that may be formed on attaching to an adherend, and has good pressure sensitive adhesion characteristics.
