Abstract: A pressure-sensitive adhesive composition and a pressure-sensitive adhesive sheet have excellent weather resistance and contain a silicone polymer having excellent curability as a main agent.A pressure-sensitive adhesive composition includes an addition reaction type silicone polymer as a component (A); an ultraviolet absorber as a component (B); and a platinum group metal catalyst as a component (C). The ultraviolet absorber as the component (B) includes a benzophenone-based ultraviolet absorber and its amount is set to a value within the range of 1 part to 4 parts by weight relative to 100 parts by weight of the addition reaction type silicone polymer as the component (A). The amount of the platinum group metal catalyst as the component (C) is set to a value within the range of 0.001 parts to 0.05 parts by weight relative to 100 parts by weight of the addition reaction type silicone polymer as the component (A).

Abstract: An electrically peelable pressure sensitive adhesive composition consists of an emulsion type acrylic pressure sensitive adhesive (A) comprising an acrylic polymer (A1) obtained by emulsion polymerization in the presence of a surfactant using a monomer mixture comprising an alkyl(meth)acrylate, and a (poly)alkylene polyol (B) having a number average molecular weight of 2000 or less, wherein a content of the component (B) based on 100 parts by mass of active ingredient of the component (A) is 3.5 parts by mass or more. In the electrically peelable pressure sensitive adhesive composition, the adhesiveness before voltage application is high, but the adhesiveness can decrease effectively by voltage application for a short time.
