Abstract: An electrically peelable pressure sensitive adhesive composition, which contains an acrylic polymer (A), a (poly)alkylene polyol (B) having a number average molecular weight of no greater than 2000, and an ammonium salt (C), has a high adhesiveness before voltage application, but the adhesiveness can decrease effectively by voltage application for a short time.

Abstract: A pressure-sensitive adhesive composition including 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).
